ESTUDlO m; LOS TRIATOMINOSEN VENEZUELA,by Pablo
Cova Garcia y Miguel A. Su~rez. Pub!. Div. Malariolo~ia, No. 11, Ministerio de Sanidad y Asistencia
Social. Caracas, Venez. 209 pp., illus.
This publication provides a useful review of the identity
and distribution of Triatominae in Venezuela. All species
of the subfamily known to occur in Venezuela are listed
and illustrated by means of photographs or drawings.
Unfortunately, most of the photographs are not well reproduced; however, together with a picture key to genera
and a di('hotomous key to species, adequate means of
recognizin~ the 12 species known to occur in Venezuela
are provided. Distribution for each species is cited by State,
District (Municipio) and town (Centros Poblados) and
relatcd to factors of altitude, temperature, and rainfall.
Uhodnius prolix us is reported to be a domestic species
prevalent throughout Venezuela. It is also the principal
vcctor of Chagas disease. Since 1952, the Division de
Malariologia has been engaged in a nationwide campaign
for control of this disease which is said to afflict a large
part of the population of Venezuela. The control program
should bcnefit materially from the information presented
here regarding the identity and distribution of the principal vectors.

This book is, in effect, a consideration of the biology
of the North American components of the monarch butterfly with special reference to migration. In it Dr. Urquhart,
who is head of the Life Sciences Division of the Royal
Ontario Museum, has brought together the results of many
years' research on the migration of the monarch. In its
later stages the study has been greatly enhanced by the
assistance of more than 300 cooperators in various areas of
the United States and Canada.
The hook will be of value to anyone intercsted in insect
migration and it is a well documented addition to the literature on this subject. It is a nicely executed volume, and the
] 2 excellent colored plates illustrate various phases of the
discussion well.

A CONTRIBUTIONTO THE HISTORY OF COMMERCIAl,PI,ST
CONTROL,by J. J. Davis, Purdue University, Published
by the Author, 84 pp., 42 Illustrations, Paper Binding,
$3.00
This paper-bound booklet has 86 pages of reduced but
legible print, and an appendix of 42 fascinating illustrations
that alone makes the publication worth having. We can
only hope that some of our other senior entomologists will
favor us with equally absorbing historical materia!.

The text is divided into two sections, I General Discussion, and II Research Data and Reference Material, both
of which cover the topics of foodplants, early stages, adult,
nomenclature,
population
fluctuations,
parasites
and
predators, mimicry, and migration. In the second section,

It is interesting to note that Dr. Urquhart believes the
theory of Batesian mimicry is untenable, although the
monarch and viceroy butterfly complex is one of the most
popularly accepted examples. He is of the opinion that the
monarch is not distasteful and that birds lIrc not significant
predators. He presents an alternate, hypothetical explanation involving a principle of protective resemblance to a
nonspecific constant in nature. That he fails to mention
and differentiate Muellerian mimicry in general statements
about protective resemblances tends to confuse the problem
somewhat.

Prof. Davis' Memories of Years Agone-Mostly
Entomological will derive both pleasure and enlightenment from his
latest work, A Contribution to the History of Commercial Pcst
Control. Thc reader will find herc a great deal of new information on the early pest control operators, a number of
whom established organizations that are now in the category of "big business". Prof. Davis also delves into the
history of PCO courses, amateur insect clubs, monuments
to insects, early insecticides, and other material of great
interest to entomologists.

pages 215 to 242 comprise
migrants than has previously been available, and many
conclusions on phases of migration, effects of climatic
conditions, overwintering, and breeding ranges are well
presented. One of the most valuable sections is a complete
report on the tagging systems utilized, including a resume
of the preliminary methods attempted and their disadvantages. Twenty separate listings in the extensive tablc
of recoveries of tagged butterflies, of flights greater than
500 miles attest to the success of the method.

1958 paper on the integumental anatomy of the adult,
published in the University of Kansas Science Bulletin.
Entomologists will find the first section of the book oversimplified, as it presents in popular style the topics men·
tioned above with a great deal of explanation. In the
second part, detailed data are presented under each of the
headings, which give a complete account of the matcrial
basis for the book. The author has, in my opinion, made
the mistake of including too many data, a large amount of
which could have been omitted or summarized without
undue sacrifice in overall value. For example, several pages
lIrc used in listing the species of milkweed by state, yet
discussion of the plant distribution patterns involved and
their significance, if any, to the distribution of the butterfly
are not given; detailed observations on variation in eggshell consumption by newly hatched larvae, on relocation
of the foodplant by larvae, et cetera, are reported without
interpretation; reports from cooperators on life history and
migrational phases are given verbatim, and many of these
do not add materially to the general conclusions. The section on migration, however, does give a more complete
picture of the habits of one of the best known insect
