The Montery Pine Resin Midge Cecidomyia 



resinicoloides n. sp. 

 By FRANCIS X. WILLIAMS. 



(Plate I) 



This paper was written in the Entomological laboratory of 

 Stanford University, and represents the biological* results 

 of nearly a year's study of a new species of Cecidomyia, whose 

 larva inhabits the resinous exudations of the Monterey pine 

 (P. radiata) growing about the University. f 



As little study has been made of pitch-inhabiting midges, 

 living as they do under such peculiar conditions, the writer 

 has endeavored to clear up as far as possible some of those 

 points in the life-history of this insect, which in other species 

 were doubtful or not fully brought out. 



Our only described species of Cecidomyia comparable to the 

 Monterey pine resin midge in general habits is C. (Diplosis) 

 rcsinicola O. S. (9). Brief notes are given on the habits of 

 the same. Comstock in his report for 1879 (2) gives a some- 



* The anatomy which has been worked out by me is reserved for 

 another paper. 



t Later (June, 1908) I observed this insect in small numbers in the 

 Monterey pine forests at Carmel, Monterey Co., Cal.
