angle produced into two long, triangular processes, the tips of which are 
slightly curved and acute;-on the posterior margin at the base of the 
inner face of these processes is a pair of short, black, blunt projections; 
ninth sternite divided by a deep broad membranous depression on the 
lower margin of which are two small chitinous rings and from the upper 
portion of which arises the long curved, highly chitinized, beak-like 
guard; in the lateral margin of this depression just below the pleural 
suture, which is complete, is a small, short, curved claw, and a short 
yellow-haired, tumid process; the posterior angle of the pleura produced 
into a short, broad, triangular point; first pair of appendages small, 
very light brown, gently curved forward, with reddish brown hair; 
second pair broad, flat, twisted, ending in a heavy, black, triangular 
tooth; third pair broadly joined to the second, elongate, distal halt 
suddenly narrowed; wing hyaline, costal and subcostal cell yellowish; 
stigma brown; a faint whitish spot in front of the stigma; Length
