BIOLOGICAL NOTES ON SOME COLORADO DIPTERA^ 



By Carl F. Baker, Fort Collins, Colo, 



The Diptera mentioned in the following notes were determined 

 either through Dr. Riley, or by Mr. C. H. T. Townsend. 



Cecidomyia siliqua Walsh. — Galls identical with those of this 

 species brought from Michigan ; are common about Fort Collins 

 on Salix amygdaloides. . 



Cecidomyia alticola Cockerell. — A gall was found at Fort Col- 

 lins on Artemisia draainailoides, which answers the description 

 of the gall of this species (see The Entomologist, 1890, p. 281). 



Subulapallipes Lw. — Large numbers of the larvae of this species 

 were obtained by Prof. Gillette, at Trinidad, under the bark of 

 a fallen cottonwood log. The flies emerged 5-21 to 6-9. A 

 description of the larva and pupa has been published by Mr. 

 Townsend. 



Argyra moeba oedipus Fab. — Reared from nests of several 

 species of Odynertis at Fort Collins. In the larval stage it is a 

 true external parasite. Flies emerged 5-3 to 6-12. 



Eristalis hirtus Lw. — Reared from maggots found in ooze
