Kern County, Cal. A single specimen in May. 



It is with much pleasure that I dedicate this rare and very in- 

 teresting species in honor of our national entomologist, Dr. C. 

 V. Riley. 



The accompanying figure is from a camera-lucida sketch, drawn 

 with the assistance of Miss Grace G. Kingsley, of this city.

COLORADO CYNIPID/E.-Part IV. 



By C. P. GILLETTE, Fort Collins, Colorado. 



HOLCASPIS 

 H. Colorado n. sp. 



Gall. I have two small twigs, each containing a cluster of three galls 

 that resemble small, dark colored galls of H. rugosa Bass. The galls are 

 slightly drawn out into a blunt point; the largest measures three-eighths 

 of an inch in length by five-sixteenths of an inch in breadth. The sub- 

 stance of the galls is more dense than in rugosa or globulus, and the cen- 

 tral cell does not separate from the surrounding cellular tissue. 



Gall-fly 9- Black, shaded with rufous. Length 3.6 mm. Head dark 

 rufous, with parts bordering mouth, middle portion of face and vertex 

 black, or nearly so; antenna 13-jointed, black, third joint slightly longer 

 than the fourth. Thorax rather coarsely punctured, and from each punc- 

 ture arises a gray hair; the general color of the thorax is black, but there 

 is a tinge of rufous upon the shoulders and between the parapsidal grooves; 

 parapsidal grooves black, and rather broad at the scutellum, but extending 

 only about half way to the collar; median groove wanting, parallel lines 

 extending back from the collar distinct, lines over base of wings black, 

 smooth and shining; scutellum grooved at base, rugose, sparsely haired,, 

 and darker in color than the mesothorax; pleurae densely punctured, the 

 punctures giving rise to fine white hairs. Abdomen black polished, sec- 

 ond segment with fine pubescence on the sides near the base, second 

 segment hardly covering more than one-third of the dorsum; the abdomen 

 is truncate and compressed laterally, the greatest depth from the dorsum 

 to the venter being greater than the length. M'ings hyaline, 4.2 mm. long; 

 nervures black, but not heavy; areolet rather large. Feet blackish, tinged 

 with rufous; tibice darker than femurs. 



Described from one living female cut from the gall Oct. 31, 

 1892. The galls were taken at Manitou, Col., September 3Oth. 



BELONOCNEMA. 

 B. Colorado n. sp. 



Gall-fly 9- General color dark rufous; head entirely rufous, but rather 

 lighter in color than the other parts of the body. Head: Facial carina 

 rather prominent, labrum elevated at the free end and slightly notched.
