MEMOIRS OF THE NATIONAL ACADEMY OF SCIENCES, 
Y ])erolivat(t (PI. Y, fig. 7). In the coIUjctiou of the United States National Museum is a 
finely preserved lleterocanipa (No. 2S0I, the moth appearing in confinement August 2, 18S2) from 
Fort Monroe, Va., which at first I regarded as ])rohahly undescribed, but which I now consider as 
a variety of IL ohliquay and somewliat similar to Grote and Robinson’s figure of R. ohliqua S . 
The larva feeds on the live oak, and was found July 28. I have prepared the following 
descriptions: 
One $ . Thorax and fore wings almost entirely of a beautiful pale green, with no white 
except two whitish costal patches, and a large white subapical oblique white patch, the black 
lines and marks, Avith the discal mark obscure. The basal and inner (i. e., that on the inner third 
of wing) lines as in rather than obllqua; discal mark black, elongated, obscure (on the 
right Aving obsolete). Extradiscal treble line as in antarte, ‘The large oblique white mark as in 
astarte^ but the black line bordering it within is not so distinct as in mtarte. 
The marginal scalloped line as in ustarte rather than ohliqua, the scallo])s being nearly as deep 
as in atitarte. Hind wings snow-white, Avith black scales on the costal edge and a small dusky 
spot oil the internal angle. The intervenular dusky dots faintly shoAvn. 
Underside as in astarte. Abdomen pale fawn color, i. e., pale ocherous brown. The abdomen 
is distinctly tufted at the end, more so than usual in the genus, perhaps because of its excellent 
state of preservation. 
Expanse of wings, S 35 mm.; length of body, 6 18 mm. 
harm (PI. XXIX, fig. 11). — (Described from a single S specimen). Length, 32 mm. Body 
cylindrical, Avithout tubercles, and of the general api>earauce of Doubleday’s figure of the larva of 
astarte. Head rounded and narrowing above, smooth aboA^e the A^ertex, Avith no traces of A'ei'tical 
tubercles, and no ti'aces of tubercles on the iwothoracic segment;' 
a reddish band on each side of the head, ending near the eyes; face 
in front pale, testaceous, not spotted. Body green, thickly dotted 
Avith reddish brown on the back and sides. No russet marks or 
reddish patches on the sides of the body. On the prothoracic seg- 
ments two dark red lines eouA^erging behind and becoming parallel 
just behind the middle of the segment and continuing close together 
and parallel to each other as far as the liinder edge of the third 
thoracic segment; thence not \wy rapidly diAWging and becoming 
farthest apart on the second abdominal segment; then couA’ergiug 
only slightly toward the fourth and fifth segments, and ending 
nearly as wide apai’t on the ninth segment. These reddish lines 
are thickened on the second abdominal segment and the space 
between is dorsally filled in partly with red, but not enough so as to make a distinct spot. Inside 
of the line on abdominal segments 1 to 10 are two fine parallel median lines, interruxited at the 
sutures. The heavier outer or subdorsal lines are not lined or broadly edged Avithiu with yellOAvish 
Avhite, as they arc in an allied species not identified (a blown larA^a in the United States National 
Museum). 
Pupa , — S of tbe usual shape and color. Head much rounded. Abdominal segments coarsely 
punctui’ed, the pits often confluent. The surface of the thorax is corrugated Avith transverse 
ridges. Hinder edge of the thorax singularly ornamented with about eight large, rounded, black 
tubercles, and the hinder edge of the eighth and ninth abdominal segments Avith about eight dorsal 
tubercles or knobs. Cremaster endiiig in two separate stout spines, which are simple, slightly 
curved, and diA^ergent. The specimen is apparently not entirely normal in shape, being rather 
slender, not full and plump as usual, and the end of the body is a little abnormal, the cremaster not 
extending outward, probably injured in pupation. The vestiges of the anal legs are rounded 
and knob-like, and indicate more plainly than I have yet seen their origin from the anal legs of 
the caterpillar.
