Mr. G. C. Cliampion on various 



31. Asti/his curvidens^ sp. n. 



Elongate, sliitiiiif;:, clothed with long, erect, black, bristly 

 hairs intermixed with scattered adpressed cinereous pul)es- 

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

 black, the basal joints of the antennse 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 ; tiie head and prothorax densely, finely punctate, 

 the latter with coarser punctures intermixed, the el} tra 

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

 antennai short^serrate, joints 7-10 about as broad as long, 

 in cJ, transverse in ?. Prothorax narrowed anteriorly. 

 Elytra long, subparallel, costate from the humeral callus to 

 near the apex, aud also with an anteriorly evanescent costa 

 on the disc ; the apices in ^ distinctly sinuate and with the 

 sutural angle sharply jnoduced, in ? very deeply emarginate, 

 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. / 



(J . Metasternum with two compressed, conical, tuberculi- 

 form prominences in the middle behind. Ventral segment 5 

 deeply arcuato-emarginate, 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.

Hah. Venezuela, Merida {Rosenberc/ : J ? ) ; ? Peru 

 [ex Deyrolle : ^J ) . 



Three males and four females, the Peruvian habitat re- 

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

 from Cliiriqui, but easily separable therefrom by the sexual 

 characters : the <J with two compressed tubercles on tiie 

 metasti-rnum and the terminal abdominal segment elongated 

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

 side of the apical emargination, the out( r tooth arcuate, the 

 inner one overlapping the corresponding tooth on the opposite 

 elytron.
