STUDIES IN AMERICAN EPHYDRIDAE (dIPTERA) 
Description. — Black; Antennae especially thii-d joint, palpi, hal teres, fore 
coxae, bases and apices of middle and hind tibiae, and their tarsi except apices, 
yellow; fore tibiae and tarsi, brown, sometimes yellow; post tarsal fascicle 
yellow. Wings yellowish hyaline, with yellow veins. 
Opaque, olive gray to yellow on head. Frons with two broad, obscured 
vittae and a dash below ocellus, black. Face sericeous, grayish to yellowish 
or golden, sometimes with two dark stripes. Mesonotum with brown vittae as 
follows: one narrow median, bifurcated posteriorly and joining the broader 
dorso-centrals and then continuing on the scutellum; a post intra-alar 
and another containing the presutural and supra-alar bristles, interrupted at 
suture; mesopleura at most with a small spot. Abdomen gray or yellowish; 
bases of segments broadly brown or with only a pair of triangular spots not 
attaining their apices. Femora gray. 
Frons quadrate, orbits parallel or slightly converging; orbital bristles mi- 
nute. Face one-half as broad as vertex, twice as long as broad, in profile con- 
vex below; foveae long and deep with carina rounded; para-facials narrow, 
concentric. Cheeks one-half as long as third antennal joint. Antennae short 
with distinct spine; arista with ten to twelve hairs. Scutellum flat, broadly 
truncate. Second costal section of wing nearly twice as long as third. 
Length. — 2.5 to 3 mm.

Notiphila frontalis Coquillett 
1897. Notiphila pulchrifrons Williston, Kans. Univ. Quart, vi, 5, (nec Loew, 
1872). 
1904. Notiphila frontalis Coquillett, Proc. Ent. Soc. Wash., vi, 97. 
Similar to N. pulchrifrons but the design more intense, espe- 
cially the frontal vittae more distinct and velvety black; in gen- 
eral appearance, a darker species. The broad abdominal bands 
attaining the apices of the segments medianly, are characteristic. 
This is one of the prettiest species of the genus, with its velvety 
black frontal vittae and golden face and orbits. 
I have seen the type of this species.
