asperate. Male having a notch at the apex of the sixth ventral 

 similar to that of texanus but much less deep, rather wider than deep. 

 Length 2.8 mm. ; width 0.5 mm. Arizona CYuma), — Mr. Wickham. 



gileusis n. sp. 



4 — Occiput finely cleft at the middle of the base; anterior angles of the 



prothorax sometimes more rounded and less apical than usual; gular 



sutures narrowly separated 5 



Occiput not modified at base or, rarely, slightly and broadly impressed at 

 the middle ; gular sutures more or less widely separated 6 



5 — Body stout and parallel, very densely punctulate and dull in lustre, 



dark piceous-brown in color, the head rather darker, the legs and an- 

 tennae very pale; head large, scarcely at all longer than wide, of the 

 usual form otherwise, the eyes well developed and convex; antennae as 

 long as the head and prothorax combined; prothorax slightly longer 

 than wide, very much narrower than the head, parallel and nearly 

 straight at the sides, the anterior angles obtuse but only very slightly 

 rounded and somewhat behind apical fourth; elytra parallel, about a 

 fifth longer than wide, scarcely two-fifths wider than the prothorax 

 and one-third longer; gular sutures very approximate, the intermediate 

 surface concave anteriorly, the under surface of the head fiat, finely 

 but strongly, extremely densely punctulate. Occipital cleft very fine. 

 Male unknown. Length 2.4 mm.; width 0.5 mm. Alabama. 



crassnlns n. sp. 

 Body parallel but less stout and rather more convex, dark piceous-brown 

 in color, the head and abdomen blackish, the legs and antennae pale 

 throughout; head extremely densely punctured and dull, the pronotum 

 and elytra less densely so and feebly shining; head nearly as in the 

 preceding species, the eyes rather less developed and the antennae 

 decidedly shorter, thicker and more incrassate distally, much shorter 

 than the head and prothorax combined; prothorax narrower and more 

 elongate, nearly a third longer than wide, much narrower than the 

 head, the sides distinctly converging and feebly arcuate from the very 

 obtuse and rather broadly rounded anterior angles — situated nearly at 

 apical third — to the broadly rounded basal angles, the disk broadly 

 impressed at each side of the median line toward base; elytra evidently 

 longer than wide, about a third wider and one-fifth longer than the 

 prothorax; gular sutures slightly less approximate, the intervening 

 surface nearly flat. Occipital cleft rather coarse, deep and distinct. 

 Male unknown. Length 2.7 ram.; width 0,45 mm. North Carolina 

 (Asheville) carolinae n . sp. 



6 — Eyes but slightly convex, not distinctly prominent and unusually small. 



Body very small, slender and parallel, rather shining, the punctures 

 throughout very minute and sparse, the pronotum less shining because 

 of stronger micro-reticulation; color pale fiavo -testaceous throughout, 

 the abdomen slightly dusky excepting toward apex; head narrow, 

 unusually elongate, the sides parallel, gradually becoming arcuate 

 basally, the base narrower than the disk, the angles obtuse but only 

 slightly rounded; prothorax distinctly elongate, nearly as long as the 

 head and only slightly narrower, the sides very feebly converging from 

 the obtusely rounded anterior angles at apical fifth or sixth to the
