246 MEMOIRS OF THE NATIONAL ACADEMY OF SCIENCES. 



Xiw. jn'rolirdtK (PI. \', tij^. 7). In the collection of the United States National ^Insenm is a 

 finely preserved Heterocanipa (No. tiS04, the moth api)eiirinj>' in conlinenient Angnst U. ISS'2) from 

 Fort Monroe, Va., which at first I regarded as probably undescribed, but which I now consider as 

 a variety of Tf. oMirjua, and somewhat similar to Grote and Robinson's figure of H. ohliqua S . 

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

 descriptions: 



One S . Thorax and fore wings almost entirely of a beautiful jiale green, with no white 

 except two whitish costal patches, and a large white subapical oblique white jiatch, the black 

 lines and marks, with the discal mark obscure. The basal and inner (i. e., that on the inner third 

 of wing) lines as in astarte, rather than obliqua; discal mark black, elongated, obscure (on the 

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

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



The marginal .scalloped line as in (fs/ar^' rather than obUqua, tlie scallops being nearly as deep 

 as ill iistarte. Hind wings snow-white, with black scales on the costal edge and a small dusky 

 sjiot on tlie internal angle. The intervenular dusky dots faintly siiown. 



Underside as in ustartc. Abdomen pale fawn color, i. e., pale ocherous brown. The abdomen 

 is distinctly tufted at tlie 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. 



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

 cyliniliical, without tubercles, and of the general appearance of Doubleday's figure of the larva of 

 astarle. Head rounded and narrowing above, smooth above the vertex, with no traces of vertical 



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



Wa reddish band 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 inai-ks or 

 reddish patches on the sides of the body. On the prothoracic seg- 

 ments two dark red lines converging behind and bei^oming ])arallel 

 just behind the middle of tlie segment and continuing close together 

 and pax'allel 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 



Fia.Se.—Fu-pa. of Heterocanipa obli(]ua .; c .< • ; o 



var.pooiirafa; cniiof bodyof cf- nearly as Wide apart on tlie ninth segment. These reddish hues 



are thickened on the second abdominal segment and the sjiace 

 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. — S of the usual shape and color. Head much rounded. Abdominal segments coarsely 

 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 separate stout spines, which are simple, slightly 

 curved, and divergent. The specimi^n 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 iiijure<l 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.
