 Pedes comjiressi ; tarsi angusti, articulis 1 — 3 parvis, imguiculari cceteris 

 conjunctis plusquam duplo longiori. Antenncs corporis dimidio paulo

 vel quarto duplo longiori, cylindrico, asperato ; 4 — 10 hrevibus sub-

The essential characters which distinguish this genus from ^go- 

 soma are the extremely short and narrow basal joints of the tarsi 

 (which, however, have the usual cushion of dense hairs on the soles), 

 the short and triangular antennal joints from the 4th to the 10th, and 

 the nearly atrophied mesosternum, which forms only a minute tri- 

 angular plate between the coxjc. The monstrous development of tlic 

 head is probably sexual. It is far more bulky than, and, exclusive of 

 the exscrted robust mandibles, twice the length of, the thorax.

A genus closely allied to uEgosoma, but differing very greatly in 

 facies ; its chief structural distinctions being the thick posterior part 

 of the head, narrow upjjcr h)be of the eyes, much less elongated third
