REPORT OF THE CONSULTING ENTOMOLOGIST, 
November 5, 1890. 
During the past season a few kinds of crop infestations have been 
reported which have been little observed before, but which are suf- 
ficiently hurtful to make it desirable to notice them. 
One of these is the American clover-seed midge, Cecidomyia 
leguminicola, Lintner, of which I have now had the maggots feeding 
in the seed-heads in summer, hibernating at the roots in winter, 
and have myself reared the gnat midge from larva; sent me. 
This midge is a little brownish, two-winged, gnat-like fly, only 
about the eighth of an inch in length.

1, Clover-seed midge; 2, maggot; S, portion of female antenna, with minnte hairs figured on 
lowest joint; 4, portion of male antenna, after Professor Riley ; 5, anchor process, after Dr. 
Lintner, all magnified ; 6, anchor process, figured from English specimens, also magnified, by 
Reporter. Nat. length given in descriptions. 
The following is the description of the clover- seed midge given 
by Professor Saunders : — 
The perfect insect is a minute two-winged fly, about the size and general 
appearance of the common wheat midge. The head is black ; the antenna? 
long, yellowish red, with sixteen or seventeen joints in the female, and fifteen 
in the male. Wings nearly transparent, clothed with many short, curved 
blackish hairs, which give them a blackish appearance ; each wing has three 
longitudinal veins, the third either forming a fork, or else becoming more or 
less obsolete towards the tip. flairy fringe of wings paler and composed of 
longer hairs than those on surface of the wing. Abdomen fuscous with 
black hairs above on each segment ; thorax black and clothed with rather long 
hairs. The male has an extended pair of clasping organs on the hinder ex- 
tremity ; the female a long pointed ovipositor, about twice the length of the 
abdomen. 1
