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 dracuncnloides, 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 cotton wood log. The flies emerged 5-21 to 6-9. A 

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

 Townsend. 



Argyra mceba oedipus Fab. Reared from nests of several 

 species of Odynems 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
