The second thoracic segment is much the shortest, and the last is 

 not shorter than the preceding. The antennae are shorter than one- 

 fourth the length of the body. The anterior feet, as in the preceding 

 species, extend forward just beyond the line of the front, and then are 

 flexed downward, the inflexed part being the hand. The thumb has 

 a seta on the under side, as well as one on the inner, at the sum- 

 mit of a triangular prominence. The body of the hand, preceding the 

 articulation with the finger, is nearly square, a little oblong. The 

 second pair of legs is quite slender and small.
