being at the same time thinner than the adjoining apex of the tro- 

 chanter the constriction is very striking.

An anomalous species, especially with regard to the antennae 

 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 

 2 posterior coxae which on the contrary are more approximated than 

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

 brown color 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 the square. Eyes small. Antennae inserted under two strong 

 protuberances rather than under a ridge, their -club 4-jointed, 

 joints 3-7 forming an inwards bent section of a circle, joints 8-10 

 strongly compressed, obliquely truncated (subperfoliated) 1 1 large, 

 conic. The 3rd joint of the maxill. palpi is of an oblongo-ovate 

 shape, the external basal angle is prolonged into a small peduncle 

 inserted in the apex of the 2nd joint, the 4th joint about the semi- 

 globose shape of which I am not quite satisfied appears to be oblique- 

 ly 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 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 subequal, 

 in the first pair strongly contracted, joint 1 of this pair produced 

 in a spine on the inside.
