Jfi/alomt/odes Townsend, Psyche, Vol. VI, p. 429; April, 1893. 
Our single species is black, the palpi yellow; eyes of male almost 
contiguous, but in the female separated at least one and one-half times 
the width of the lowest ocellus; abdomen on last three segments gray 
pollinose, the second and third segments in the female each bearing a 
pair of large triangular black spots, indistinct or wanting in the male; 
front pulvilli of female less than two-thirds as long as the last tarsal 
joint; length, 4 to 5 mm. White Mountains, X. II.; Xew Bedford,

The synonymy of the last two with CEstrophasia, and of Neoptera 
with Phasiopteryx, has already been given by Brauer and Bergen- 
stanun. 1 Phasiopteryx is not sufficiently distinct from CEstrophasia to 
be retained as a distinct genus. Our species have three postsutural 
and two sternopleural macrochsetse : 
1. Wings destitute of brown rnai kings 3. 
Wings distinctly marked with brown 2. 
2. Discal cell crossed by a brown crossbar) d, hind crossvein not wholly 
bordered with brown, a brown border to the fifth vein and a 
brown crossband beyond the discal cell; yellow, an ocellar dot 
and usually from one to three spots or a fascia on hind margin of 
each segment of the abdomen, and sometimes one or more on the 
thorax, black ; length, 1 to 5 mm. Toronto, Canada; Franconia, 
N. II.; Philadelphia, Pa., and Florida. (Biol. Cent. Amer., Dip

Discal cell not crossed by a brown crossband, hind crossvein bor- 
dered with brown, second basal and anal cells, and wing in 
front of third vein from humeral to slightly beyond small cross- 
vein, also a brown crossband extending over the hind crossvein 
and bordering the fifth vein except near base of discal cell, 
brown ; yellow, the upper part of the occiput sometimes blackish, 
thorax sometimes black dorsally, or with two vitta&and an ante- 
rior spot black; abdomen with the hind margin of each segment
