Dicrodiplosis gillettei Felt 

 191 1 Felt, E. P, Econom. Ent. Jour., 4:549 



The midge was reared September 11, igii from an apical budlike 



deformity on P i n u s s c o p u 1 o r u m collected the preceding 



July by Prof. C. P. Gillette of Fort Collins, Col. Similar galls were 



also taken by Prof. E. Bethel of Denver. This species is doubtfully 



referred to Dicrodiplosis and appears to be closely allied to D. 



rubida Felt, being most easily distinguished by the color of the 



abdomen and the short, stout apical process of the terminal antennal 



segment. 



Gall. Diameter i cm, length 1.25 cm. This is a budlike deformity 

 covered with brownish scales and, in one instance, with rudimentary 

 needles arising from the sides.

The female described below was found in the collections of the 

 United States National Museum, labeled Diplosis cocci- 

 darum, Mayaguez, Porto Rico, January 1889, August Busck. 

 It was presumably reared from a scale insect and is with little ques- 

 tion one of the species referred by Coquillett^ to Diplosis 

 coccidarum Ckll.
