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].
