31. Astylus curvidens, sp. n. 



Elongate, shining, clothed with long, erect, black, bristly 

 hairs intermixed with scattered adpressed cinereous pubes- 

 cence, the vestiture of the legs and under surface cinereous; 

 black, the basal joints of the antennas partly red, the elytra 

 with an oblong streak at the base, the outer margin to near 

 the tip, and two stripes on the disc (one near the suture, 

 abbreviated anteriorly, the other abbreviated behind and 

 placed a little exterior to the basal patch, with which it is 

 sometimes connected anteriorly), the sutural and marginal 

 stripes transversely coalescent just before the apex, flavous 

 or luteous ; the head and prothorax densely, finely punctate, 

 the latter with coarser punctures intermixed, the elytra 

 roughly punctured. Head small, subrostrate, the eyes large; 

 antennas short, serrate, joints 7-10 about as broad as long, 

 in <$ , transverse in ?. Prothorax narrowed anteriorly. 

 Elytra long, subparallel, costate from the humeral callus to 

 near the apex, and also with an anteriorly evanescent costa 

 on the disc ; the apices in <$ distinctly sinuate and with the 

 sutural angle sharply produced, in ? very deeply emargiuate, 

 with the sutural and outer angles each produced into a long 

 curved tooth, those at the sutural angles overlapping, the 

 outer one very strongly arcuate. 



c? . Metasternum with two compressed, conical, tuberculi- 

 form prominences in the middle behind. Ventral segment 5 

 deeply arcuato-em alginate, 6 long, subcylindrical (with the 

 dorsal portion forming a long tube, which is cleft laterally at 

 the tip), Tegmen feebly bifurcate at tip, deeply sulcate at 

 the apex above, the apical portion thickly clothed with long, 

 curled, blackish hairs. Penis-sheath sharply pointed, curved 

 upward at the tip. 



Length 7-8^, breadth 2|-3 mm. (c? ? .) 



Hah. Venezuela, Merida (Rosenberg :"(??); ? Peru 

 (ex Deyrolle : £ ) . 



Three males and four females, the Peruvian habitat re- 

 quiring confirmation. Extremely like A. vittatus, Gorh., 

 from Chiriqui, but easily separable therefrom by the sexual 

 characters : the $ with two compressed tubercles on the 

 metasternum and the terminal abdominal segment elongated 

 and subcylindrical ; the ? with a very long tooth on each 

 side of the apical emargination, the outer tooth arcuate, the 

 inner one overlapping the corresponding tooth on the opposite 

 elytron.
