the 4th joint, about the semiglobose shape of which I am not 

 quite satisfied, appears to be obliquely inserted in the tip of 

 the preceding. Thorax oral, of a similar shape to that of 

 the former, anterior margin slightly emarginated. Scutellum 

 obsolete. Elytra with the traces of a humeral costa, sepa- 

 rately rounded off at the apex. Legs strong, 2 posterior coxae 

 not more distant from each other than the 4 anterior ones ; 

 tibiae elongated, bent at the base and apex, at the latter place 

 slightly narrowed, subcylindric and hairy ; tarsi with joints 

 1-4 sub equal, in the first pair strongly contracted, joint 1 of 

 this pair produced in a spine on the inside.

Antennae art. 1° apice bi-acuminato, 2 et 5, 3 et 4, 7 et 8 inter se 

 subaequalibus, 6 quarto paulo minore, obovato, 7-8 subglobosis apice

 Thorax subrotundatus, basi 4-foveolatus. Elytra apice singulatini

 canalicidata, apice acuminata. 



This species stands in the middle between S. alatus and 

 pselaphoides. To the former it is allied by its general appear- 

 ance rather than by anything else, differing from it very much 

 in the structure of the antennae and the mesosternal carina. 

 To the latter on the contrary it is allied by similarity in the 

 structure of the said carina, differing, however, from it in 

 general appearance. The color is that of S. alatus, but a 

 shade or two darker, the insect being at the same time larger 

 and altogether more robust. The eyes are small. Antenna!
