DIPTERA. _ 63 
The eyes are greenish; back of abdomen with white triangular lon- 
gitudinal spots. 
The early stages of this species were traced by De Geer (Mem. Ins.), 
who found the larva to be terrestrial and carnivorous. His observa- 
tions on this species were the first giving information upon the early 
habits of the Tabanide. 
THE BANDED BREEZE FLY. 
( Therioplectes cinctus Fab.) 
The banded breeze fly, or orange- belted horse-fly, is a species of some- 
what larger size than the greenhead. It is rather less abundant than 
the black breeze-fly, which it somewhat resembles, excepting the orange 
or reddish band on the abdomen. It is limited more to the Eastern 
States. It was described by Fabricius at the same time as Tabanus 
atratus (Ent. Syst., Vol. LV, p. 366). 
Hematopota pluvialis Linn. 
According to Kollar this is one of the most troublesome species. He 
says: 
It is not much larger than the common horse-fly, and is chiefly distinguished by 
its large green eyes, through each of which run four brown undulating bands, 
The body is gray with brownish cross stripes; the wings gray with brown spots. 
It frequents meadows and pastures and attacks horses and horned cattle in sultry 
weather before rain, nor does man escape. Although the wound it inflicts is sharp, 
it does not produce any lasting itching or burning. 
This statement regarding the injury caused does not agree entirely 
with the statements of other authorities, for in Kirby and Spence’s 
Entomology (p. 93) we find a quotation from MacLeay which reads as 
follows: 
I went down the other day to the country, and was fairly driven out of it by the 
Hematopota pluvialis, which attacked me with such fury that, although at last I did 
not venture beyond the door without a veil, my face and hands were swollen to that 
degree as to be scarcely yet recovered from the effects of their venom. I was 
obliged on my return to town to stay two days at home. Whenever this insect bites 
me it has this effect, and I have never been able to discover any remedy for the tor- 
ture it puts me to. 
Also, in Linnzeus under the description of the species: 
Like T. cwcutiens, this little insect fixes on the hands, face, and legs, exciting a 
painful inflammation in the part where it has drawn blood. 
THE EAR FLy. 
(Chrysops vittatus Wied.) 
This is a rather small species, yellow in color, with black stripes and a 
broad, smoky band across the middle of each wing. It was described 
in 1821 by Wiedemann, but without reference to its habits.
