with black at apex and near the scutellum, each having in addi- 

 tion a large sutfnsed black cloud at the middle. Prothorax as 

 w'de as the head, densely punctate toward base. Length 2.1-2.7 

 mm.; width 0.7-0.8 mm. 



The large series before me is from Galveston, Texas, and repre- 

 sents without much doubt the true texanus of LaFerte, which was 

 unknown to LeConte. 



In the present species, which has been full3' and accurately de- 

 scribed by LaFerte, the male has the fifth ventral but slightl}'- 

 longer than the fourth, broadl}^ rounded at apex, just visibly 

 sinuato-truncate for a short distance in the middle, with the ad- 

 joining surface feebly-, transversely impressed, the genital segment 

 very feeblj- sinuate at tip, with the surface feebly and transversel}'^ 

 impressed. The male intromittent organ consists of a superior 

 corneous flattened and very shallow sheath, nearl}- one-half as 

 long as the abdomen, the short basal part of which is parallel at 

 the sides, the remainder ver\' elongate, bent downward, with the 

 sides straight and gradually convergent throughout to the apex, 

 the latter slighth' dilated in the form of a small flattened sub- 

 circular button. The intromittent duct proper is partially en- 

 closed along the under surface of the sheath ; it is membranous 

 or feebly coriaceous in structure, and fully as long as the protec- 

 tive sheath, from which it can be bent downward ; it is somewhat 

 distorted in the specimen examined but appears to be of a sub- 

 C3'lindrical form.

Moderatel}^ stout, highly polished throughout above, dark rufo- 

 testaceous, the anterior parts frequently picescent ; elytra colored 

 as in texanus. Head convex, rather longer than wide, finely, 

 sparsel}' but distinctly punctate, semi-circularly rounded behind, 

 the e^'es rather large and prominent, with extremelj" short sette 

 as usual. Prothorax scarcely as wide as the head, not longer 

 than wide, convex, acutely constricted rather behind basal third, 

 finely but strongly, sparsely punctate, the punctures closer toward 

 base. Elytra barely three-fourths longer than wide, twice as wide 

 as the prothorax, quite distinctly wider at the middle than at 

 base, the apex rather broadly rounded ; punctures coarse and 

 sparse, finer and with the surface duller toward apex. Abdomen 

 finely granulato-reticulate but somewhat shining. Legs rather 

 short and thick. Length 2.5-2.75 mm.; width 0.7-0.85 mm.
