truncate with mucronate tip. Stigma black, peduncle semihyaline, the 

 four abdominal segments anterior to the larval skin with three longitudinal 

 rows of spines ; those of the dorsal and lateral rows large, hyaline, curved 

 and barbellate, and rising from very prominent tubercles ; subvental row of 

 somewhat smaller spines ; the tubercles point forward while the spines 

 curve outward and backward. Duration of pupal stage : 7 to 8 days. 



The larvae of this species are gregarious in small numbers 

 beneath the bark of old dead trees in moist places, or on the
