SUBFAMILY CHRYSOMYINAE 195 
sides of the body near the legs and on the neck. The bird, al- 
though weak and emaciated, was able to flutter away after the 
maggots were removed. It was first discovered by John R. 
Sandige.”’ 
The variety hirudo cuprea was deseribed by Shannon and 
Dobroscky from a female which differed from the typical form 
in being yellow green with metallic bronze luster, and covered 
with whitish pollen, about as in aenea. I find no other differences. 
Perhaps male specimens might show distinctions; but, until such 
specimens have been found and differences noted, it seems best 
to synonymize the name with dirudo. Johnson (1925, 1929, and 
1931) reported the rearing of two maggots of this variety from 
the neck of a sparrow at Middleboro, Mass., but Ihave seen no 
eastern specimens of hirudo. 
The variety hirudo parva was described by Shannon and Do- 
broscky from one male and one female. The female lacks the 
middle and hind legs and the abdomen, and the male head and 
part of the thorax have become lost; neither, therefore, is suit- 
able for further description. Except for the lack of a weak third 
notopleural bristle, the subspecies hirudo parva fits the deserip- 
tion given for hirudo by Shannon and Dobroscky. However, since 
so many important parts of the two specimens are lacking, I 
am not able to draw definite conclusions. The specimens are 
very small, due possibly to insufficient larval food, and bristle 
development is often considerably reduced under such condi- 
tions. The squamae are infused with orange brown. The type 
locality given for hirudo parva is Kansas, but this is an error. 
Dr. L. L. Adams originally received these specimens from 
S. W. Williston, who collected the material at Greeley, Colo. 
Adams sent the material to Aldrich and he passed it on to Shan- 
non. , 
Two specimens, one male and one female, reared from larvae 
collected under the skin of nestling yellow warblers, at Fort 
Collins, Colo. (Mrs. 8S. H. Fry), pupated June 28, 1911, and 
emerged as adults July 10, 1911. The male differs slightly in 
head proportions and the female in color, but in all other char- 
acters these specimens agree with the typical form. 
The three varieies were separated by Shannon and Dobroscky 
by means of the following characters. 
1. General color dark, with rather heavy pruinosity........ 2 
General color bronze. .hirudo cuprea (Shannon & Dobroscky) 
2. Squama darkened...hirudo hirudo (Shannon & Dobroscky). 
Squama white...... hirudo parva (Shannon & Dobroscky).
