have arrived at the conclusion that a half-tone from a photograph 
gives the best result. The half-tones are not up to the standard of 
American work by this method and are much inferior to those made 
in Europe with similar copy. In spite of this, which may be remedied 
in the future, the work is a contribution of the greatest value to 
students and is a strong hint to others to do likewise in illustrating 
what they study. 
Vol. 1, No. 5, July roth, 1912. “Fifty New Species; Notes on the 
Genus Alpheias.” Many new species of moths, mostly from the west- 
ern and southwestern United States, are described in this paper. A 
study is made of the Pyralid genus Alphcias Ragonot. The charac- 
ters of some of the genera are given with tables for their separation, 
and some new genera and species are described. Some notes and corri- 
genda are appended. Four plates with many figures follow the text. 
Vol. 1, No. 6, “On the Generic Types of North American Diurnal 
Lepidoptera,” July 25, 1912. The authors in this paper have used the 
“first species” principle and listed the genera accordingly “to see what 
the result would be.” They give tables showing the result of the 
first species method, and alongside of each genus the result of Scud- 
der’s work by “elimination.” Inasmuch as the Committee on Nomen- 
clature of the International Zoological Congress has adopted a dif- 
ferent plan of procedure, we are still in the dark as to which genus 
to use. It looks like a case of “go as you please.” Genera are liable 
to give all but the strongest intellects brain-fever. However this 
may be, we are indebted to the authors for their views on an inter- 
esting though tiresome subject—H. S. 
THE MACROLEPIDOPTERA OF THE WortD, By Dr. ADALBERT SEITZ, PH. 
D.—This colossal work is published by Dr. Seitz with the help of an 
able corps of assistants, experts or authorities in the various branches of 
this immense subject. The study of the Macrolepidoptera has grown 
apace and for a time the illustrated works were entirely inadequate to 
cover the subject. Hundreds of new species were not figured and even 
those persons who had access to large libraries found it difficult to 
keep up-to-date. Of course, descriptions were available, but there are 
few persons that like the drudgery of relying solely on descriptions. 
When we consider the fact that this work when completed will con- 
tain 930 plates and 30,000 figures in color we can realize what an un- 
dertaking it has been and how much it will contribute to our knowl- 
edge of the butterflies and moths of the world. The illustrations as a 
whole are excellent and the explanatory text as full as it could be, and 
the work kept within reasonable bounds. Good figures are essential in 
this study, as while they do not accomplish everything, they save an 
immense amount of time and, if necessary, one can always refer to
