punctures slightly finer at the middle. Abdomen finely, sparsely punctulate 

 toward the apex, less finely at base. Middle coxae separated by nearly half the 

 coxal width. Metasternum a little longer than the first ventral segment. Legs 

 not stout. (PI. V, fig. 48). 



Male. — Front and middle tibiae very feebly sinuate and mucronate within at 

 the apex, hind tibiae not visibly modified; fifth ventral segment a little longer 

 than the fourth, with a distinct transverse apical impression occupying two-thirds 

 the length of the segment. 



Female. — Not seen. 



Length 1.9 mm. 



Hub.— South Carolina. 



Very few specimens seen. It is probably nearest to serrata and 

 amplicollis ; from the first of these it may he distinguished by its 

 stouter form and longer tempora, and from the latter by the thorax 

 obviously widest in front of the middle and less nearly equal in 

 width to the elytra. 



C cribricollis sp. nov. — Elongate, parallel, convex, rufotestaceous; pubes- 

 cence grayish, moderate in length, recumbent. Head coarsely, closely punctate, 

 eyes prominent, tempora rather short. Antennae barely reaching the bind angles 

 of the prothorax, joints 7 and 8 subglobular, 9 and 10 distinctly transverse. Pro- 

 thorax distinctly wider than the head, but very slightly narrower than the 

 elytra at the humeri; sides evenly rounded, widest very near the middle, base 

 scarcely narrower than the apex, margin crenulato-denticulate ; surface coarsely 

 suhcribrately punctate, basal fovea feebly impressed. Elytra parallel, sides 

 feebly arcuate, apex obtusely rounded; striae scarcely impressed, punctures 

 moderately coarse toward the base; intervals more finely uniseriately punctate. 

 Sterna coarsely, rather closely punctate; first ventral sparsely but distinctly 

 punctate, following segments finely, sparsely punctulate. Middle coxae separated 

 by a trifle less than half the coxal width ; metasternum a little longer than the 

 first ventral. Legs moderate. (PI. V, fig 49). 



Male. — Front and middle tibiae feebly sinuate and mucronate within at apex; 

 fifth ventral transversely impressed at the apical margin. 



Female. — Unknown. 



Length 1.8-2 mm. 



Hub. — Texas (Beeville). Two males taken by Mr. Schwarz in 

 November. 



The coarsely, closely punctate thorax is the most obvious distin- 

 guishing characteristic of this species, but there is a still more pecu- 

 liar one which is quite likely sexual. The claws of the hind tarsi 

 are much longer than the other feet, and the inner one exceeds the 

 outer one in length and is straighter and sinuate at tip. 



C amplicollis sp. nov. -Elongate, subparallel, convex, rufotestaceous- 

 pubescence moderate, recumbent. Details of form and sculpture substantially 

 as described in Carolina, except in the following respects: in amplicollis the eves 

 are a little larger, and the tempora a trifle longer, the tenth antenna! joint is dis-
