Odontomyia (Odontomyia) occidentalis James, 1936 



Figures 135, 136, 138 



Description. — Puparium: length 20 mm; width 3.5 mm; other 

 characters as given in key to species. 



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

 springs. 



Material examined. — Sleeping Child Hot Springs, reared June 

 28, 1930, 2 puparia, WSU. 



Discussion. — The mensural data given above were taken directly 

 from the puparia. These specimens had the apical segments turned 

 up in the typical manner making accurate measurements an 

 impossibility.

 mm; width 3.5-3.9 mm, mean 3.7 mm; other characters as given 

 in key to species. 



Biology. — Larvae of this species have been collected from a peat 

 bog and from a pool of unidentified type.

 width 2.9-3.6 mm, mean 3.25 mm; other characters as given in key 

 to species.

 percent saline water in Death Valley.

 May 1, 1958, D. P. Furman, 2 larvae, WSU. 



Subfamily Nemoteliiiae 



James (pers. comm.) placed the genus Nemotelus in the Stratio- 

 myinae solely on the basis of adult characters; however, when both 

 adult and larval characters are taken together and compared with 

 similar characters of other members of that subfamily, the differences 

 observed are great enough to warrant separation. For this reason 

 I have erected the new subfamily Nemotelinae. 



SuBFAMiLiAL CHARACTERS. — As givcii in key to subfamilies.
