42 CLARK —NEW AMERICAN SPHINGIDAE Pe 
afficta exhibit any constant differences. From comparison of one male 
taken at Nassau, with a long series from Cuba and South America, it 
appears that there is a real difference between the race of the Bahamas 
and specimens from both the other localities. In the Nassau specimen the 
upper side of the fore wing is much more variegated. The ground tone is 
lighter; and the markings, besides being darker and heavier, are in general 
coarser. The light bands on the upper side of the hind wing are more 
prominent than in the typical form, and the outer band is really white 
toward the anal angle, and along this angle the white is more extended. 
A white dash, 3 mm. in length, starting on SC5 at a point 4 mm. distant 
from the distal margin, extends diagonally toward R1. The markings on 
the under side of both fore wing and hind wing are much darker and 
heavier, and the submarginal dark band on both wings is broader. The 
hind wing below is lighter in color toward anal angle. 
The general appearance and character of the insect vary so 
markedly from afflicta that, while one would wish to have further 
material, the form appears to deserve a subspecific name. A 
specimen of afflicta from Cuba is reproduced for purposes of com- 
parison (Plate III, figure 3).

A much whiter species than any other Proloparce except P. leucoptera, 
which in general wing coloring it closely resembles. In the pattern of the 
fore wing, it is like P. florestan. There are, however, the following differ- 
ences. The upper side of the fore wing is white, with light and dark 
brown markings. The two diseal streaks R38-M2 are less distinet, and 
sometimes vestigial. The markings of the fore wing are much lighter in 
color, and there is no greenish tint. The head, thorax and abdomen above 
are brown, with light scales interspersed. The hind wing above is brown 
instead of black, as in P. florestan. It has the same markings but the white 
at the anal angle is more extended, The under side of the fore wing is
