NO. 35G9 SOLDIER FLY LARVAE — McFADDEN 27 



range as far north as Oregon and Washington on the west coast and a 

 third species, subulata, is found throughout many of the Eastern 

 States. Fourteen species have been collected from the southwest as 

 adults, but the genus Adoxomyia, which contains 11 of the 14 species, 

 is known only from 3 puparia that lack the head capsule. 



Habitat of larvae. — All specimens collected to date have been 

 taken from decaying or wounded cactus. Larvae of an unknown 

 species of Cyphomyia have been reported as occurring under the bark 

 of cedar logs in Honduras.

Genus Cyphomyia Wiedemann, 1819 



James (pers, comm.) recognizes 2 species in this genus: Cyphomyia 

 bicarinata WUliston and C. marginata Loew. Larvae have been col- 

 lected for both species, but because the specimens of C. bicarinata are 

 an early instar, pin mounted, and in poor condition, I have substituted 

 the description of a neotropical species, C. pilosissima Gerstaecker.

Description. — Puparium: length 20.1 mm; width 2.9 mm; other 

 characters as given in key to genera. 



Biology. — Larvae of this species have been collected from papaya 

 in Florida. 



Material examined. — Florida: Miami, July 11, 1917, T. E.

Figures 83-85 



Description. — Mature larva: length 21 mm; width 5 mm; dorsally 

 the anterior and posterior margins of the thoracic and of the fu'st 7 

 abdominal segments somewhat elevated with low transverse ridges oc- 

 cupying approximately the anterior and posterior foiu"th or fifth of the 

 segment; ventrally these areas are only slightly elevated.
