The legs are all similar in structure. Along the inferior margin of 

 the merus, carpus, and propodus are a few hairs. 



The first two segments of the abdomen are short, followed by one 

 long rectilinear segment. The sides of the abdomen are almost parallel, 

 the posterior end being three-fourths as wide as the anterior end. The 

 posterior extremity of the terminal segment is produced in a very 

 obtuse point, which does not extend far beyond the lateral angles.
