Psyche 
[ March 
Wings of moderate length and breadth; cross-vein be- 
tween first radial sector and median vein is beyond fork 
of median, no cross-vein between first and second radial 
sectors near their bases, one between last radial sector and 
radius, that between median and cubitus is longer than 
that between cubitus and its fork; the first gradate series 
(of 6 or 7) form a nearly even series across, but very little 
disjointed, and less oblique than in related species. The male 
appendages are deeply forked. 
Length forewing 8 mm., width 3 mm. 
From Argentine Pass, Colo. (Cockerell). Type M. C. Z. 
19436. 
Allotomyia borealis sp. nov. 
Pale yellowish; in the male the face is shining black, in 
the female with a transverse spot below antennae; prono- 
tum dark on sides ; mesonotum and metanotum dark above 
base of wings; abdomen brown; forewings marked with 
dark at the gradate series, and some spots toward base, 
and with marginal brown spaces alternating with white 
spaces; many of the veins with dark dots; hind wings 
wholly pale, without marks. Venation much as in A. ft- 
delis; no cross-vein from last radial sector to radius, one 
from first radial sector to second near its base, and a little 
before the cross-vein from the first radial sector to the med- 
ian vein; first series of gradates further out than in A. 
fidelis, as near to second series at these to the outer margin. 
Male genitalia very different from A. fidelis; seen from the 
side extremely broad toward base. 
Length of forewing 8 mm. 
A male from Hillsboro, N. H., 12 June. A female taken 
by Mrs. Slosson many years ago at Franconia, N. H. agrees 
in the markings of the wings. Type M. C. Z. 19437. 
Megalomus uniformis sp. nov. 
Body, antennae, and legs pale yellowish, unmarked ; 
wings the same, but the gradate series are narrowly brown, 
and a dot on the connection of cubitus and median, and faint 
brown borders of apical forkings; the dark dots seen on 
the veins of other species are here practically absent ; hind 
wings slightly embrowned around margin. Costal area
