^'"- 3^«9 SOLDIER FLY LARVAE — McFADDEN 41 



Genus Nemotelus GeoiTroy, 1762 



In North America this genus contains 33 species that are divided 

 into 2 subgenera: Nemotelus (12 species) and Camptopelta (21 species). 

 I have seen puparia of 2 species of Camptopelta and larvae of a single 

 species of Nemotelus. 



Generic characters. — As given in key to genera. 



Subgenus Nemotelus Geoffroy, 1762 



The specimens representing this taxon consisted of 3 headless 

 puparia in poor condition. 



Nemotelus (Nemotelus) kansensis Adams, 1903 



Figures 120, 123 



Description.— Puparium: length 7.2 mm (less head and prothor- 

 ax) ; width 2.6 mm 



Biology.— Larvae of this species were collected from a salt spring 

 (probably from the margin) 



Material examined.— Missouri: Petersburg, June 1, 1955, P. J. 

 Spangler, 3 puparia, WSU. 



Discussion.— The pattern on the dorsum of the body segments and 

 the arrangement and placement of setae both agree very closely with 

 that of Nemotelus canadensis Loew
