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 aj^pears 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 cox6e 
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.
