lowing joints are somewhat stout, gradually and feebly incrassate, 

 the eleventh rather small and obliquely obtuse. The eyes are 

 large, very coarsely faceted, minutely and scarcely Ansibly setose, 

 and with a small but distinct rounded emargination ; they extend 

 very nearly to the base, and the occij^ut is strongl3\ transversely 

 arched and elevated ; epistomal suture distinct ; last joint of the 

 maxillary palpi right-angled, of the labial moderately dilated, 

 concave, densely spongy and also flnely setose beneath. Pro- 

 thorax transverse, with the sides parallel. Scutellum moderate 

 in size, narrowly truncate and feebly bidentate at apex. El3'tra 

 ample. Middle coxte moderately separated, the posterior widely 

 sepai'ated b}'^ a broadly rounded abdominal projection. Legs mod- 

 erately slender, the posterior femora longer and thicker, finely 

 pubescent ; tibiae slender, without trace of terminal spurs ; tarsi 

 rather short, the basal joint much elongated. Abdomen with 

 the basal segment very large, more than equalling the entire re- 

 mainder, witli scarcel}^ a trace of the dividing suture; second 

 distinctly longer than the third ; fourth short in both sexes. 

 Yestiture of the bod}' very short, decumbent, dense, consisting of 

 very minute, and longer and sparser hairs, intermingled. 



This genus is quite distinct, and is the only one which occurs 

 in both the Atlantic and Pacific coast faunal regions. The 

 species may be known thus : — 



Smaller and narrower, more opaque, the punctuation much denser; sides of 

 the prothorax not at all prominent behind the apex...l. briimiipeniiis 



Larger and more obese, more shining, much less densely and less evenly iiunc- 

 tate, the sides of the prothorax more angulate anteriorly 2. saginatus 



The sexual characters are extremely feeble throughout.

 strongly, rather densely punctate ; eyes large and convex, sep- 

 arated by three-fourths of their own width or somewhat more,
