which are much less approximated at the base than those of the 

 rest of the species belonging to this group, and with regard to 

 the two posterior coxae, which, on the contrary, are more approxi- 

 mated than in any of the species just referred to. The insect is 

 of the light brown colour of the two former, but larger and more 

 depressed. The head is strikingly large and heavy, of the width 

 of the thorax; in its hind part, which is strongly transverse, 

 the oval form prevails over that of the square. Eyes small. 

 Antennae inserted under two strong protuberances rather than 

 under a ridge ; their club four-jointed, joints 3-7 forming a 

 section of a circle bent inwards; joints 8-10 strongly com- 

 pressed, obliquely truncated (subperfoliated), 11 large, conic. 

 The third joint of the maxillary palpi is of an oblongo-ovate 

 shape ; the external basal angle is prolonged into a small pe- 

 duncle inserted in the apex of the second joint ; the fourth joint, 

 about the semiglobose shape of which 1 am not quite satisfied, 

 appears to be obliquely inserted in the tip of the preceding. 

 Thorax oval, of a similar shape to that of the former ; anterior 

 margin slightly emarginated. Scutellum obsolete. Elytra with 

 the traces of a humeral costa, separately rounded-oif at the apex. 

 Legs strong; two posterior coxae not more distant from each 

 other than the four anterior ones ; tibiae elongated, bent at the 

 base and apex, at the latter place slightly narrowed, subcylindric 

 and hairy; tarsi with joints 1-4 subequal, in the first pair 

 strongly contracted, joint 1 of this pair produced in a spine on 

 the inside.

This species stands in the middle between S. alatus andpsela- 

 phoides. To the former it is allied by its general appearance 

 rather than by anything else, difi'ering 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
