Contarinia coloradensis Felt 



1912 Felt, E. P. N. Y. Ent. Soc. Jour., 20:240-41 



A female, provisionally referred to this genus, was reared from a 

 large budlike deformity on Pinus scopulorum collected by 

 Prof. E. Bethel, Denver, Col. It was also received from Prof. 

 C. P. Gillette, Fort Collins, Col., and was reared again in 19 13. 

 This is probably the true gall maker.
