Marc!]| | CLARK — SOME UNDESCRIBED SPHINGIDAE 113 
The maculation and general characteristics are in all respects like those 
of the male, except the antennae. These are shorter, less than one third 
the length of the fore wing, slender, filiform, light brown. 
Xylophanes maculator wolfi Druce. 
Al. ant. long., 2, 388 mm. Al. ant. lat., 9, 16 mm. Marg. ext., 9, 
19 mm. 
Habitat. — Manaos, Brazil. This female was taken by my friend, Rev. 
A. Miles Moss, March 5, 1917, a thousand miles up the Amazon. It is a 
perfect specimen. 
Its markings are in all respects similar to a drawing made of one of the 
males in the Tring Museum. Proximally of the main line of the fore wing 
there is much more uniformity of color than in X. maculator, and the con- 
trast is stronger between the uniform light coloring of the proximal portion 
of the fore wing and the portion lying posteriorly of the main line. This 
contrast is especially marked toward the hinder angle where the fore wing 
is very dark. This point of difference from X. maculator has not, I think, 
been previously noted. 
Euproserpinus euterpe Edw. 
Al. ant. long., 2,17 mm. Al. ant. lat., 9,7mm. Marg. ext., 2,11 mm. 
Habitat. — Southern California. One female in coll. B. Preston Clark, 
given me by my friend Jacob Doll, and received by him through C. V. 
Riley in 1888. 
Edwards’ description of H. euterpe is remarkably fine. There 
are a few points, however, which may well be stated. 
One type is a male, though spoken of as a female. 
The ground tone of the female specimen, as well as that of a male in my 
collection, is brown, while that of H#. phaeton is black. There is less con- 
trast between the marginal discal band of the fore wing than in phaeton, 
and the band itself is more deeply incised. 
The abdomen, in both the male and the female, has pale side tufts. 
These are much less marked in the male, and this is true also of phaeton. 
The antennae of the male of ewterpe are, as noted by Edwards, of equal 
size throughout, and not clubbed as in phaeton. They are also slightly 
longer, The antennae of the female of euterpe are markedly longer than
