are rather closely tuberculatecl. The apex of the. elytra is 

 minutely mucronate. Tbe male has the anal segment of the 

 abdomen broadly but not deeply excavated, with a small pencil of 

 hairs on each side of the anal cavity.

This species resembles Amycterus in the excavated and some- 

 what carinated forehead and rounded apical margin of the elytra. 

 In other respects it is not unlike the last described species, but 

 differs from it in the more coarsely tuberculated thorax without 

 medial line and in the very rugose deeply punctured sculpture 

 of the elytra. It is also much less thickly clothed with scales 

 than T. catenulatus. 



39. — Talaurinus scabrosus. 



Oblongo-ellipticus niger confertim cinereo-squamosus, rostro 



valde excavate postice utrinque subfoveolato, thorace remote 



verrucoso, elytris subseriatim punctatis undique remote 



tuberculatis apice mucronatis. 



Mas : segmento anali antice leviter postice profunde excavato.

This insect is very like T. verrucosus, differing from it chiefly in 

 being more thickly clothed with scales, and in being less rugose 

 and much more thinly tuberculated on the elytra. The afliuity 

 to the genus Amycterus is very evident.
