front smoother. Thorax a little narrower than the head, one-fourth longer than 

 wide, sides nearly parallel, median smooth space well defined, on each side of 

 which the punctures are moderately fine and dense, sparser near the sides. Elytra 

 a little wider than the thorax and slightly longer, black, subopaque, apical border 

 narrowly yellow, surface densely punctured, the punctures finer than those of the 

 thorax and coarser than of the head. Abdomen sparsely punctured, the punc- 

 tures equalling those of the head. Legs yellowish testaceous. Length .28 inch ; 

 7 mm. 



Male (Complete form).— Third ventral with a moderately long setigerous plica 

 at middle, fourth with a similar plica and prolonged in a lobe at its posterior bor- 

 der very broad at base and reaching the middle of the sixth segment; last ventral 

 entire (PL ],fig. 7). 



Male [Imperfect form).— Yonrih. ventraX not lobed, but squarely truncate, the 

 third and fourth segments plicate at middle as above. (Cab. LeC.) 



Female. — Third and fourth ventral segments simple, without fovea or plica. 

 At first glance this species recalls some forms of Cafius. Among the 

 species of the present genus it can only be compared with pallipes, from 

 which it difiers in too many particulars to require special note. 



I have seen two complete males, two imperfect males and three females. 

 Occurs in Louisiana and Florida. 



5. C Itlgubre Lee. — Form slender, entirely piceous or nearly black, shining, 

 sparsely pubescent. Antenn;e shorter than the head and thorax, rufo-testaceous, 

 joints 3-6 darker, the third not longer than the second. Head oval, suddenly 

 constricted at base, hind angles rounded, sides parallel, surface coarsely and 

 sparsely punctured. Thorax very little narrower than the head, one-fourth hm- 

 ger than wide, sides nearly parallel, median smooth space well defined, on each 

 side of which the punctures are large and deep, but not numerous. Elytra 

 scarcely wider than the thorax and equal in length, with very coarse and deep 

 punctures substriately arranged. Abdomen above and beneath relatively coarsely 

 and sparsely punctured. Legs yellowish testaceous. Length .26 inch ; 6. .5 mm. 



Male [Imperfect form). — Third ventral segment bearing a transverse setigerous 

 plica at middle, fourth segment with a small fovea; seventh ventral entire (PI. 1, 

 fig. 8). 



Female. — Third ventral with a very short plica almost fovea like in form; 

 smooth ventral entire (PI. 1, fig. 9). 



The only variation observed in the nine specimens before me is that 

 some are slightly paler in color, varying, however, less than hadium. I 

 have seen but two males as above ; it may be possible that the form with 

 fourth ventral lobed does not exist. 



Occurs in Florida. Hubbard and Schwarz. 



6. C. obliqtinni Lee. — Piceous, nearly black, shining, very sparsely pubes- 

 cent. Antennse shorter than the head and thorax, yellowish testaceous, second 

 and third joints nearly equal. Head oval, sides obliquely narrowing behind the 

 eyes, hind angles scarcely evident, surface shining, very sparsely punctate. Thorax 

 a little narrower than the head, scarcely one-fourth longer than wide, disc more 

 convex than usual, median smooth space well defined, on each side of which the
