black; the principal markings are substantially the same as in the male, 
e-cepting that the transverse black band is in most cases much more deeply 
indentated, although in one of the females before me the band hasa more 
even outline than in the male, and that the semi-transparent spot on sec- 
ondaries varies in shape, being rounder and less regular in some; the out- 
er apical black spot in some is disconnected at the middle, thus forming 
two regular triangles; the borders are generally heavier, especially on 
secondaries, where the spots interiorly are larger and better defined, and 
dotted with black, particularly towards the anal angle. 
I suspected at first that this species would prove to be Affacus splen- 
didus, 1)e Beauv, but the description and figure (Ins. Afr. et Amer, ) in 
several respects do not tally with the insect here described. 
The accompanying plate, figuring both male and female, will fur- 
nish the exact outlines and markings of this exquisite species. 
The cocoons are of close texture, with but one covering, oval in 
shape, and are firmly attached to the twig or branch, somewhat in the 
manner of ‘‘Cyzfia,;" the color is dirty silvery white streaked with light 
or dark brown, and the chrysalis is covered with a whitish powder, like 
in the Catocale. 
Cocoons of this moth were found in Southern Arizona by Mr, 
Robert Driver. 
Platysamia Polyommata, nov. sp. see Plate, figure 3. 
Female; Expanse five inches. 
The shape is lfke that of ‘‘Cecropia”. 
Head and thorax dull black, collar pinkish-white, a tuft of red hairs 
at base of thorax: abdomen dull black with a double row of lateral red 
stripes, enclosing small black spots; legs dull black; antennze small, pec- 
tinated and brownish black. 
Wings dull black with the costa on primaries slightly inclining to 
gray; no basal bands, nor light abdominal margin to secondaries; the 
spots in the median fields are small and plain white with no edging, on 
primaries they form a small triangle, and on secondaries simply a_bar. 
A wide band of white near the outer margin runs through both wings and 
makes a decided curve towards the apex on primaries, where it is tinged 
with pale fulvous; beyond this band outwardly, the color on primaries is 
erayish-black, lighter towards outer margin; the apical spot is black, sur- 
rounded by dark gray, then bordered inwardly by a bluish crescent edged 
black, and outwardly bya dull reddish shading; between each of the veins 
below the apical spot, and bordering closely on the white band, is a blu-
