 behind. Hind coxae approximate, slightly prominent, tibiae without

Washington, Mr. H. Ulke, to whom I am indebted for an excel- 

 lent series of specimens; it is found under ground, about the roots 

 of trees. 



This insect has a deceptive resemblance to Euplectus interruptus, 

 but besides the absence of eyes, it differs by the shorter and stouter 

 antennae, and the elongate well impressed dorsal stria of the elytra. 



INO Lap. 

 I. reclnsa. — Depressed, shining, testaceous, elytra slightly dusky near the 

 tip; head large, obsoletely punctulate, with a faint trace of a longitudinal im- 

 pressed line. Prothorax narrower than the head, but a little wider than long, 

 strongly narrowed from the front angles to the base, which is very narrow and 

 imperceptibly margined ; sides sinuous with a subacute tooth about the middle ; 

 surface very obsoletely punctulate. Elytra narrow at base, gradually wider 

 behind, rounded at tip, longer than head and prothorax. Abdomen with four 

 exposed segments, slightly dusky at the sides. Length 2.3 mm. 



Columbus, Texas; E. A. Schwarz; beaten from branches of trees, 

 very rare. The head is widest at the eyes, which are small and 

 rounded; the antennae are half as long as the body. This genus is 

 remarkable among Oucujidse, for having no appearance of lateral strife 

 on the prothorax.
