of the body, the intermediate joints slightly flattened and 

 widened, third joint scarcely longer than the second; tho- 

 rax about twice as broad as long, the sides rounded and 

 narrowly margined ; surface entirely impunctate ; at each 

 side near the basal margin an obsolete oblique depression 

 is seen ; elytra very finely and closely punctured , the in- 

 terstices very finely wrinkled" near the sides , the latter also 

 accompained by a more or less distinctly impressed longi- 

 tudinal groove from the shoulder to the apex ; legs piceous 

 or black ; underside obscure fulvous or piceous. 



The species described here is closely allied to *S. hadia 

 Erichs. aud S. fiava Clark , from both of which it difi"ers 

 in its smaller size and colour of the antennae; S. nigri- 

 cornis Baly is another closely allied species in which how- 

 ever the third joint of the antennae is twice the length 

 of the second; the thorax also is much more transverse 

 and the legs are fulvous. 



Sebaethe afflnis, n. sp. 



Oblong-ovate , convex , pale fulvous or testaceous ; an- 

 tennae (the first 3 joints excepted) black; thorax scarcely 

 visibly, elytra very finely punctured. — Length 3 — S^/g lines. 



Head impunctate , transversely grooved between the eyes ; 

 frontal tubercles transverse , very flat and nearly contigu- 

 ous; carina short and thick; palpi incrassate, the terminal 

 joint acute and conical; antennae not quite extending to 

 half the length of the body, black, the first 8 joints ful- 

 vous; third joint twice as long as the second; thorax 

 transverse , more than twice as broad as long , the sides 

 rounded and narrowly margined , the anterior angles thicke- 

 ned ; surface microscopically finely punctured ; scutellum 

 broad , impunctate ; elytra slightly wider at the base than 

 the thorax , very little widened below the middle and ra- 

 ther convex , more distinctly punctured than the thorax ; 

 prosternum very distinct , shallowly longitudinally channel-
