short sensitive hairs, and has the first article two and a half times 

 longer than the three other articles taken together. 



The second pair of antennae extend a little beyond the thorax; the 

 last article of the peduncle is more than twice as long as the penulti- 

 mate article; the flagelluin is composed of about twenty to twenty- 

 four articles, with the exterior articles for the greater part long 

 and without apical hairs. The clypeus occupies all the area between 



the mandibular palps and 

 is produced in a long 

 tubercle. The first seg- 

 ments of the thorax are 

 ornamented in the mid- 

 dle transverse line with 

 short and deep furrows; 

 the four posterior seg- 

 ments are ornamented 

 with long transverse fur- 

 rows. 



All the epimera have 

 the posterior angle pro- 

 duced in an acute, coni- 

 cal process, those of the 

 sixth segment being the 

 longest of all, those of 

 the seventh segment be- 

 ing the shortest of all. 



The first three pairs 

 of legs are almost as 

 in E. elegantula, fur- 

 nished, however, with 

 more hairs. The last 

 three pairs of legs are 

 a very little shorter and

hairs. The seventh pair 



of legs have the third to the sixth articles furnished on the inferior 

 side toward the inner margin with many short spines, and are orna- 

 mented toward the exterior margin with many hairs; the fifth article 

 is a very little shorter than the sixth, and much longer than the fourth; 

 the fourth article is a little longer than wide. 



The last segment of the abdomen is furnished at the base with a 

 short and deep median depression and on either side with a deep and 

 rather large lateral excavation; the median depression is bicarinated 

 in the bottom; the posterior margin is a little more than a third part
