H. C. FALL. 65 



cornis is closer, but this has a 6-jointed funicle, the form is 

 slightly more slender, the prothorax relatively smaller, the 

 pubescence less conspicuous and the elytral striae less im- 

 pressed. 



CONOTRACHELUS Sch. 

 C. atokamis n. sp. — Form and size oi pusillus, brown or piceous, 

 densely clothed with subcontiguous oblong oval ochreous and white 

 scales and sparse short recurved bristles, which are difficult to detect 

 except in profile. The ochreous scales predominate and determine the 

 general color ; the white ones are aggregated in small spots on either 

 side of the middle and at the sides of the prothorax, at the base of the 

 third elytral interspace and at the anterior and posterior thirds of the 

 elytral disk, the latter also with scattered small blackish areas which 

 are due as much to exposure of the derm as to the color of the scales. 

 Beak rather stout, moderately curved, but slightly longer than the 

 prothorax in the c?, a little longer in the 9, sulcate and clothed with 

 filiform scales behind the insertion of the antennae, which in the d^ is 

 at the apical third, and in the 9 at about the middle ; beyond the an- 

 tennae rather coarsely punctate in the c?, smoother and more finely 

 punctate in the 9 . Prothorax wider than long, sides parallel and 

 feebly arcuate in basal half, narrowed in front with moderate apical 

 constriction ; surface neither densely nor very coarsely punctate, en- 

 tirely without sulci or costae. Elytra two and two-thirds times as long 

 and a little less than twice as wide as the prothorax, one-third longer 

 than wide, humeri nearly rectangular, narrowly rounded, sides straight 

 and parallel for about half their length, then gradually narrowed and 

 parabolically rounded at apex ; strial punctures rather fine, the inter- 

 vals wider than the striae, feebly convex, the alternate ones not appre- 

 ciably more prominent except on the declivity. Beneath sparsely 

 clothed with squamiform hairs or narrow scales, punctuation not very 

 coarse, that of the ventral segments uniform and rather close. Meso- 

 sternum not protuberant ; thighs feebly annulated and armed with a 

 small tooth; claws with an acute basal tooth. Length, 2.8 mm. ; 

 width, 1.5 mm. 



Type. — c?" ; from Atoka, Indian Territory. Three examples 

 collected by Prof. Wickham. 



One of our smallest species, resembling in a general way 

 pusillus, but differing by the completely non-costate elytral 

 intervals, non-protuberant mesosternum and generally finer 

 punctuation. Pusilhis seems to be very rare in collections. 

 Two specimens, agreeing in all essentials with the type, were 

 taken by the writer many years ago near Providence, Rhode 

 Island. It was described from Florida.
