DIPTERA. 71 
THE HIpPoBOSCID-LIKE TABANID. 
(Goniops hippoboscoides Aldrich. ) 
Under the above name Mr. J. M. Aldrich has described a very pecu- 
liar fly, that has the structure of the 
tabanids, but the general appearance 
of a hippoboscid, although it is not 
known but only surmised thatit may 
have a parasitic or semiparasitic 
habit. 
Since nothing is known as to the . 
habits or the early stages of the '¢- 3—Eggmass : rhein cestuans (from 
species, and it would seem to be of 7 
very rare occurrence, it will suffice for the purpose of this paper to 
Fic. 36.—Chrysops fugaz (original, from drawing by Miss L. Sullivan). 
simply refer to the original description and figures (Psyche, Vol. VI, 
pp. 236, 237). 
Family LEPTIDA. 
(Snipe Flies.) 
Most of the species in this family are of medium size, with rather 
slender bodies, and the abdomen generally somewhat tapering. They 
are sparsely haired; the head short; the eyes in the males set close 
together; the antenn short, and the third joint with a terminal bristle 
or slender style. 
The larve are carnivorous and live in the ground or else in decaying 
wood, in sand, moss, or water. 
The species generally prey upon other insects, but according to Dr, 
S. W. Williston ‘‘some Western species of Symphoromyia suck blood. 
as do the horse-flies.” 
As he does not particularize as to the species observed, the animals 
attacked, or the method of attack, we must let this brief mention suflice.
