of dorsum transverse or very feebly obtuse-angulate produced, 

 and the tegmina which, though reduced, are normally in large 

 part apparent, readily distinguish this interesting species from 

 A^. proavus Rehn and Hebard. 



The previously unknown male of this species is a smaller 

 replica, in all ambisexual features, of the female sex.

With the exception of one female, the series is uniform fuscous black 

 in general coloration. The velvety black humeral triangles are weakly 

 indicated in the males, slightly more conspicuous in the females. One 

 fem.ale is of the bicolored type which is also found in proavus; in this 

 example, the portions cephalad of the posthumeral triangles are black- 

 ish brown, those caudad of that point distinctly paler, saccardos umber 

 shading to sepia toward the medio-longitudinal carina on the pronotum. 



Specimens Examined : 6; 4 males and 2 females.

An Entomologist's Handbook. 



An entomologist's handbook or compendium is very much needed, 

 especially by economic entomologists. It is planned to compile such a 

 handbook, which will include principles and methods of studying the 

 life histories of insects, of conducting held experiments and demonstra- 

 tions, handy tables for field workers, et cetera. It is desired to have 

 references, or better, to have separates of all published notes dealing 

 directly or indirectly with the subject and to have details, and if pos- 

 sible, drawings or photographs as well, of cages, apparatus, metjiods, 

 etc., as yet unpublished. The handbook will be a compilation and full 

 credit given to all contributions. 



The co-operation of entomologists is solicited. — John J. Davis, Box

^ Long continued search in this area, with a view to securing fur- 

 ther specimens of this insect, proved fruitless.
