212 ENTOMOLOGICAL NEWS [xx XI, "20 
ing. Through the kindness of Prof. J. G. Sanders and Mr. 
A. B. Champlain of the Bureau of Plant Industry, Harris- 
burg, Pennsylvania, I am enabled to examine their collection 
in this genus, consisting of two males and one female from 
Pennsylvania and Virginia, and two males from Colorado. 
Of the above material from the Bureau of Plant Industry, 
Mr. Champlain writes: ‘I wish to call your attention to the 
fact that all were collected from Pine. Knull took the Vir- 
ginia specimens from pine; I got the Colorado specimen fly- 
ing around cut and infested pine logs, and Sanders collected 
the Pennsylvania specimens flying around cut white pine, 
the latter being attacked by Monohammus, Ips, and other 
pine insects. It is probably a predator on pine insects in 
both adults and larval stages.”’ 
Critical examination of the above material, supported my 
earlier supposition that there were two distinct species repre- 
sented respectively by the eastern and western specimens. 
They are all typically Pogosomae and possess the following 
characters in common which may be considered of generic 
or subgeneric importance: 
Shining, sparingly pilose species. | Head twice as broad as 
high, deeply excavated between the eyes above; ocelli on a 
prominent, conical tubercle; antennae inserted near ocellar 
tubercle, far above center line of eyes. Facial profile pro- 
duced in form of an obtuse cone to opposite the end of first 
antennal joint, but leaving a space below antennae straight 
and nearly vertical. First antennal joint twice as long as 
second; third as long as first and second together. Proboscis 
straight, conical, pilose at apex above. Scutellum without 
true macrochaetae. Abdomen elongate; segments somewhat 
constricted at incisures. Femora thickened beyond middle; 
fore tibiae without spur. First submarginal cell divided by 
a cross vein from anterior branch of third vein; first posterior 
cell narrowed or closed at margin; posterior cross vein and 
apical cross vein of fourth posterior cell parallel but not con- 
tinuous. 
Genotype.—Asilus maroccana Fabricius, 1794, [Original 
designation].
