North American Species of TrogopJilceus. 359 



narrower than the apex; the latter truncate; apical angles slightly ob- 

 tuse, very narrowly rounded; basal broadly rounded; disk very broadly 

 and extremely feebly bi-impressed, extremely minutely and densely 

 punctate, the punctures throughout the head and pronotum in mutual 

 contact. Elytra very slightly wider than long, distinctly wider and 

 one-half longer than the prothorax, very feebly impressed near the 

 suture, rather finely and densely punctate, the punctures more than 

 twice as wide as those of the pronotum, and separated by scarcely their 

 own diameters. Abdomen very slightly narrower than the elytra; 

 sides parallel and nearly straight; border moderate; surface minutely, 

 feebly reticulate, and minutely and rather densely punctate. Length 

 1.5 mm. 



Texas (Galveston 5); New Jersey (Cape May 3). 



A small species, with very fine, rather dense punctuation and 

 decidedly alutaceous lustre. It is sometimes partially cas- 

 taneous, with paler legs, probably from immaturity. 



On the occiput, in a transverse line midway between the 

 posterior extremity of the eyes and the base of the head, there are 

 two feeble tubercles, mutually slightly more distant than either 

 from the lateral margin; they are excessively minute and only 

 observable under oblique illumination. 



The significance of these two minute tubercles is not easy to 

 divine. I have not noticed them elsewhere in the Oxytelini_, 

 and they are not evident in some specimens of the present 

 species, which may possibly be females. Perhaps they may con- 

 stitute a rudimentary beginning or a degradation of the ocelli, 

 which constitute so marked a feature of the great and hetero- 

 geneous tribe Omalini. 



36 T. modestusn. sp. — Rather robust, dark castaneous; abdomen 

 piceous- black; legs and antennae throughout pale flavate; pubescence 

 very short, moderately dense; integuments rather shining. Head large, 

 very slightly narrower than the prothorax, rather strongly convex, 

 finely, densely punctate; punctures less dense in the middle; promi- 

 nences large, rather strong; eyes moderate and finely faceted, mode- 

 rately convex and slightly prominent; tempera about two-thirds as 

 long, broadly rounded and nearly as prominent; antennae short, mode- 

 rately robust, slightly shorter than the head and prothorax; club strong; 

 second joint nearly as long as the next two combined, fourth scarcely 

 as long as wide, outer joints transverse. Prothorax widest slightly 

 before the middle; sides broadly, nearly evenly arcuate from apex to 

 base, slightly straighter and more convergent near the latter, which
