and in the second basal and anal cells; third vein and anterior branch

they cross each other; lateral angles furnished with a broad, irregular- 
shaped chitinized appendage, the upper inner angle of which is drawn 
out into a rather long, flattened, slightly curved claw; the inner (anter-

ninth tergite small, posterior margin with two-small crescent-shaped 
incisions between which is a sharp, triangular, furrowed tooth; ninth 
sternite with a very deep U-shaped incision which is filled with a pair 
of appendages the posterior faces of which are chitinized and each 
terminating in a pair of backward-projecting claws, the lower ones long 
and curved, the upper ones short, less strongly chitinized, inconspicu- 
ous; pleural suture complete; upper pair of appendages reddish brown, 
broadly spatulate, furnished with long, brownish/and yellowish hairs;
