Maren?1] CLARK — SOME UNDESCRIBED SPHINGIDAE 103 
This species is distinct from Lapara coniferarum. It is a 
much larger insect. The markings of the fore wing are fainter, 
and often so vestigial that the wing is unicolorous, lacking even 
the two longitudinal postcellular dashes. These differences 
become very evident as one compares series of the two forms. 
The genitalia also are entirely different.

The male of this remarkable species has not heretofore, I think, been 
described, although the female was described by Rothschild and Jordan 
fifteen years ago (Revision of the Sphingidae, p. 220). 
The coloration of the male is in all respects like that of the female. The 
remarkable feature of the male is the shape of the fore wing. The costal 
margin runs from the base almost straight, very slightly convex; but at a 
point 12 mm. from the apex the margin curves sharply posteriorly. The 
apex of the wing is rounded, and 1 mm. in width. The distal margin is in- 
cised very sharply from the wing apex, at first following the line of SC5; 
it is then scalloped to R1, where it is bluntly angled. The distal margin 
is again deeply scalloped between R1 and R2, and scalloped less deeply 
between the other veins, to M2. Hinder angle rounded. The distance from 
the angle on R3 to the apex of the fore wing, in a direct line, which really 
measures the faleate portion of the wing, is 15 mm. 
The hind wing is sharply pointed at the apex, the distal margin is slightly 
wavy, and the hinder angle rounded. I know of no Sphingid with such a 
singularly shaped fore wing.
