Discussion. — The examination of a great number of specimens 

 of this common species gave a rather comprehensive picture of the 

 range — North America from Maine and Ontario west to Oregon and 

 south to Virginia, Louisiana, and Mexico. An interesting point that 

 results is that pusillus is not a member of the West Indian fauna as 

 reported by several earl}^ workers and refuted by later authors, includ- 

 ing Barber (1939). 



Uhler's (1894, p. 227) habit note that "This small insect lurks 

 beneath rubbish in sandy places, where it matches the color of the 

 ground and is thus easily overlooked," summarizes all of the available 

 ecological information on this form except the frequency and abun- 

 dance with which it comes to light.

Diagnosis. — The four marginal pegs on the jugum, the small size 

 (1.2-2.1) and the presence of coarse punctures on the disc of the calli 

 will separate this species and hasidentatus from all others in the genus. 

 The females of these two forms are as yet not separable with certainty, 

 but the males of pusio lack spines or angulation on the ventral margin
