ment, the third joint broadly rounded within. Prothorax a little wider than 

 long, widest and rather broadly rounded at the sides ; apex three-fourths as 

 wide as the base, lateral subbasal fovese large. Elytra not as long as wide, 

 one-half longer than the prothorax and nearly twice as wide ; sides broadly 

 arcuate behind, oblique ; humeri scarcely at all exposed at base ; humeral 

 width barely more than two-thirds of the subapical ; discal stria extending 

 rather behind the middle. Abdomen a little shorter than tlie elytra and nearly 

 as wide, the first dorsal slightly longer than the second. Leys moderate. 

 Length 1.2 mm. ; width 0.45 mm. 



Pennsylvania. 



The single type appears to be a female and is about equal in 

 length to tenellus but broader. Another female from Illinois is a 

 little larger, with slightly longer elytra, but I cannot perceive that 

 it is specifically distinct. 



T. Terticalis n. sp. — Minute, piceous-black and polished throughout, 

 the legs and antennse pale, subimpunctate except the elytra which are sparsely 

 puuctulate ; pubescence long, coarse and sparse. Head across the eyes fully 

 as wide as long, narrower than the prothorax ; eyes at about one-half their 

 length from the base, large, prominent ; antennal tubercles large, convex, 

 vertexal fovese large, visible from above, the spicules large and very near the 

 fovese, distant from the tubercles ; antennae rather stout, one-half as long as 

 the body, the club not quite as long as the funicle, first three joints decreasing, 

 third rather longer than wide, four to eight slightly transverse, the fifth but 

 little wider than long, ninth to eleventh abruptly wider, increasing in width ; 

 third palpal joint broad, triangular. Prothorax distinctly wider than long, 

 •widest and rounded at the middle, the apex three-fourths as wide as the base ; 

 lateral subbasal fovese deep. Elytra not quite as long as wide, two-thirds 

 longer than the prothorax and distinctly less than twice as wide ; sides oblique, 

 rounded behind ; humeri but slightly exposed at base, the humeral width 

 three-fourths of the subapical ; discal stria extending rather behind the 

 middle. Abdomen a little narrower and much shorter than the elytra, the 

 first dorsal much longer than the second. Length 1.2 mm. ; width 0.45 mni. 



District of Columbia. 



The type is a female and resembles spicwhyer; it may be readily 

 distinguished however by the position of the subfrontal spicules, 

 which are very near the fovete, also by the larger and more basal 

 eyes, more transverse prothorax and some other characters. Both 

 of these species differ from minor in their much smaller size, 

 blacker coloration, much larger vertexal fovese, and larger sub- 

 frontal spicules.
