shorter, the legs and antennae very long and slender, and the 

 club of the latter as long as the footstalk. The pygidium is 

 inclined inwards and the abdomen greatly contracted and 

 completely covered by the elytra. In addition, the elytra of 

 three females collected by M. Vitalis are of a deep red 

 colour, whilst those of the males are black.

This little insect, of which I know the male only, is remark- 

 able for the extreme abbreviation of its hind-body, the elytra, 

 which cover the much-contracted abdomen, being conjointly 

 as broad as they are long. The pronotum, on the other hand, 

 is narrow and attenuated in front, and the clypeus is longer 

 than in the other known species. Instead of being rounded 

 in front this is truncate, and the labrum is extruded and 

 placed almost in the same plane. The maxillae are furnished 

 with long and prominent tufts of hair. 



The peculiarity of the mouth-structure renders it probable 

 that a new genus may ultimately have to be made for this 

 species, but it is desirable to await the discovery of the 

 female in view of the great disparity between the sexes of 

 these insects.
