A TRYPETID BRED FROM GALLS ON BIGELOVIA. 



BY C. H. TYLER TOWNSEND, LAS CRUCES, NEW MEXICO. 



A round, white, woolly gall was found on stems of Bigelovia (sp. 

 probably graveolens) in several localities in western New Mexico the past 

 summer, from June 19 to 22. Those found June 19 were old galls, and 

 were met with near Luera Spring, in Socorro county. On June 21 the 

 fresh galls were found in numbers near Gallo Spring. Sometimes two or 

 three were found near each other on the same stem or twig of the plant, 

 and in one case three galls were found joined together, forming a triple 

 gall. On June 22 they were found extremely common west of Apache 

 Spring, thus seeming to increase in number in a westerly direction, as did 

 also the patches of Bigelovia, every plant of which was full of them. The 

 last two localities are on the Pacific slope of the Continental Divide, the 

 first locality (Luera Spr.) being to the east of the divide about 40 miles. 



Many of the galls found June 22 were opened at the time and dis- 

 closed several hymenopterous pupse which were at first taken for the gall- 

 maker. Some also contained a small white larva, probably belonging to 

 the hymenopteron. Most of the galls, however, contained puparia which 

 were taken for those of a tachinid, but which were in reality the puparia 

 of a trypetid and the original gall-maker. None of the puparia were 

 noticed to contain the fly, and numerous galls that were picked and kept 

 in pill boxes for several months developed no trypetids. It was later 

 found, however, that two of the puparia extracted from the galls at this 

 date and placed in alcohol contained the pupa within. The credit for the 

 breeding of the fly is due to Professor C P. Gillette, who sent me sped-
