edge of the medians being a little before the centre of the 
laterals, nearly evenly spaced and very slightly unequal in 
size, the medians separated from each other by a space which 
exceeds their diameter and by about a diameter from the 
laterals. Posterior medians about as large as the anterior 
medians and nearly at the same distance from them and from 
the posterior laterals, which are about as large as the anterior 
laterals and separated from them scarcely 3 diameter. 
Stridulating organ consisting of a large cluster of fine close- 
set bristles clothing the distal third of the posterior surface

close-set bristles at the distal end of the anterior surface of 
coxa 1.—one just above, and the other, of slender and more 
abundant bristles, just below the suture.
