emargination present; cerci subtrigonal in section at the base, forked 

 at about two-thirds the length, the dorsal arm directed some- 

 what dorsad and shorter than the other branch which is produced 

 horizontally, the whole cercus having a strong mesad curve and 

 in the type specimen the right one is smaller than the left, the forks 

 being more rudimentary than in the left, which is, apparently, normal ;* 

 subgenital opercule short, not reaching the caudal margin of the 

 eighth abdominal segment, moderately inflated, from the ventro-caudal 

 portion of the opercule is developed a finger-like process as long 

 as the ninth dorsal abdominal segment, the apex slightly broader 

 than the shaft, slightly curved dorsad and broadly sulcate on the 

 same face. Cephalic femora very slightly longer than the pronotum 

 and mesonotum together, proximal flexure distinct; cephalic tibiae ex- 

 ceeding the femora by about the length of the pronotum. Median 

 femora equal to the mesonotum in length ; median tibiae considerably 

 longer than the femora; median metatarsi about as long as the 

 remaining tarsal joints. Caudal femora equal to the five proximal 

 abdominal segments in length; caudal tibiae slightly longer than the 

 six proximal abdominal segments ; metatarsi about as long as the 

 remaining tarsal joints. 



General color russet, the thorax lined laterad with French green; 

 head with two longitudinal bars on each side, one caudad of the eye, 

 dorsum of the head suffused with olive-green, antennae greenish, eyes 

 vandyke brown ; apex of the abdomen suffused dorsad with bluish 

 black; limbs faintly and irregularly annulate with raw umber and 

 cinnamon.

The type is the only specimen of this interesting species seen 

 by the author. 



♦Whether this condition of the right cercus is normal for the species 

 or not the author cannot say. It may be that the left is normally 

 larger than the right or the alternative is that the right one in the 

 ■type specimen is stunted. The left cercus is so well proportioned that 

 the possibility of its being an excessive development can hardly be 

 entertained.
