MEMOIRS OF THE NATIONAL ACADEMY OF SCIENCES. 



Yav. 2)c>'<>llf((ta (PI. V, fig. 7). In tlie collection of the United States National Museum is a 

 finely preserved Heterocauipa (No. 2804, the moth api)earing in confiuemeut August 2, 1SS2) from 

 Fort Monroe, Va., which at first I regarded as ])robably undescribed, but which I now consider as 

 a variety of H. ohiiqita, and somewhat similar to Grote and Kobinson"s figure of H. obliqua S . 

 The larva feeds on the live oak, and was found July 28. I lia\e prepared the following 

 descriptions: 



One i . 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 aTid nnirks, with the discal mark obscure. The basal and inner (i. e., that on the inner third 

 of wing) lines as in astarte^ rather tliau ohliqua; discal mark black, elongated, obscure (on the 

 right wing obsolete). Extradiscal treble line as in antarte. The large oblique white mark as in 

 (istitrte, but the black line bordering it within is not so distinct as in astarte. 



The marginal scalloped line as in astor^e rather than ohliqua, the scallops being nearly as deep 

 as in astarte. Hind wings snow-wliite, witli black scales on the costal edge and a small dusky 

 spot on the internal angle. Tlie iuterveuular dusky dots faintly shown. 



Underside as in astarte. Abdomen jiale 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, S 18 mm. 



Laroa (PI. XXIX, flg. 11). — (Described from a single $ specimen). Length, 32 mm. Body 

 cylindrical, without tubercles, and of the general api)earance of Doubleday's figure of the larva of 

 astarte. Head rounded and narrowing above, smooth above tlie vertex, with no traces of vertical 



tubercles, and no traces of tubercles on the prothoracic segment; 

 a reddish baud on each side of the head, ending near the eyes; face 

 in front pale, testaceous, not spotted. Body green, thickly dotted 

 with 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 converging behind and becoming parallel 

 just behind the middle of the segment and continuing close together 

 and parallel to each other as far as the hinder edge of the third 

 thoracic segment; thence not very rapidly diverging and becoming- 

 farthest apart on the second abdominal segment; then converging 

 only slightly toward the fourth and fifth segments, and ending 

 nearly as wide apart on the ninth segment. These reddish Hues 

 are thickened on the second abdominal segment and the si)ace 

 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, interrupted at the 

 sutures. The heavier outer or subdorsal lines are not lined or broadly edged within with yellowish 

 white, as they are in an allied species not identified (a blown larva in the United States National 

 Museum). 



Pupa. — $ of the usual shape and color. Head nnicli rounded. Abdominal segments costrsely 

 punctured, the pits often confluent. The surface of the thorax is corrugated with 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 with about eight dorsal 

 tubercles or knobs. Cremaster ending in two sei)arate stout spines, which are simple, slightly 

 curved, and divergent. 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.
