Described from twenty-five flies, all females, reared from galls 

 taken at Manitou, Col., Sept. 30, 1892. Flies began emerging 

 from the galls November loth. 



H. brevipennata n. sp. 



Galls globular, from i 1.5 centimeters in diameter, attached 

 singly to the underside and always near the margin of the leaves 

 of Quercus undulata. The central cell is held in place by a rather 

 abundant growth of frail radiating fibres, more or less branched 

 towards their outer ends. The outer shell is very thin, and is of 

 a straw color more or less stained with rusty-brown. The species 

 seems to be badly parasitized, as twenty galls taken at Manitou, 

 Col., September 3Oth, gave but two of the gall-flies, and these I 

 cut from their cells. 



Gall-flies. Rufous, 3.5 mm. in length, wings not quite attaining the tip 

 of the abdomen. The only black parts are the eyes, ocelli, two or three 

 joints at the tip of the antenna and the almost black color of the terminal 

 segments of the abdomen. In one specimen the head is quite dark, in- 

 dicating that in some specimens it might be almost black. Head rugose, 

 sparsely set with gray pubescence; antennae i3-jointed, third joint slightly 

 longer than the fourth, and fully as long as the four terminal ones together. 

 Thora.i' rugose-punctate, not very densely haired, parapsides very dis- 

 tinct and extending the whole length of the mesothorax, middle groove 

 absent; scutellum rather coarsely rugose and with two shallow foveae at 

 base. Abdomen globular, second segment covering fully two-thirds of 

 the dorsum and sparsely pubescent at the sides, the hairs arising from 

 small punctures, ovipositor sheaths very short. Feet uniformly rufous 

 and quite hairy. M'ings not quite reaching the tip of the abdomen, ner- 

 vures black, the transverse and radial ones being specially heavy and 

 smoky along their margin. In the apical cell are two dusky patches, one 

 near the tip and one under the radial nerve near the base, areolet wanting. 



Described from two females, both alive and active; cut from 

 the galls October 3ist.

A NEW ICHNEUMONID. 



G. C. DAVIS, Agricultural College, Michigan. 



While out collecting one day last Summer I happened to spy 

 a very odd looking parasite crawling over the leaves of a low 

 bush in the oak woods near the college. It looked odd because 

 it had only small stubs instead of Well developed wings. At the 

 first glance the wings appeared to have been injured, or perhaps
