180 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



June 27 one larva of the same species was found on oak near the fair ground, Dis- 

 trict of Columbia. It measures 2^ inches in length and is of a dark grayish-brown 

 color, the dorsum being more brown whilst its sides and venter are dark gray. 

 Warts and stigmata are of the same color as in the smaller larva from Florida. The 

 minute oval spots are replaced by a rather indistinct marmoration, which on the 

 dorsum is somewhat orange and on the sides and venter more olive. The moth 

 issued July 23. 1886. 



One larva of the same species was fouud by Koebele in Virginia, 

 June 12, 1882, feeding on bickory. 



The larva is long and slender, of nearly even width throughout; the 

 head flattened in front; mesothoracic segments with lateral and dorsal 

 tubercles which are very rough ; on the fourth abdominal segment are 

 two conical dark dorsal tubercles ; there are two minute dark tubercles 

 on the fifth, and two slightly larger ones nearer together on the eighth. 



Abbot states that it feeds on Clematis rosea, and in his manuscript 

 drawings that it feeds ou Pyrrlioimppus carolinianus. 



Larva. — Its length is If inches. Color gray with a slight yellowish tinge, and the 

 whole surface closely marked with minute, transversely oval, blackish or pale 

 dusky spots. Head small, quite flat, and closely spotted with darker gray, Protho- 

 rax small, scarcely broader than the head, with a broad, somewhat paler median and 

 narrow subdorsal line. Its posterior margin is provided with a transverse row of 

 four small black tubercles. The mesothorax is much larger aud very abrupt in 

 front; the small anterior wrinkles are somewhat yellowish, whilst the large poste- 

 rior swelling is of the color of the body, being ornamented anteriorly by four trans- 

 versely 7al, conspicuous black spots, aunulated with a brownish-yellow ring. The 

 four black warts on the metathorax are only externally bordered with brownish 

 yellow. The two dorsal rows of warts on abdominal segments 1 to 7, are arranged 

 as usual, are small, black, aud also with brownish-yellow border externally. The 

 posterior pair of dorsal spots on the fourth abdominal segment is replaced by two 

 prominent, somewhat transversely oval, black tubercles with rounded tip, aud 

 orauge-yellow external margin at base. The eighth segment is also somewhat 

 swollen above, is marked with two large black median spots, an orange annular with 

 black center each side, and a transverse orange spot with black center behind the 

 swellmg. Stigmata orange with black annulus. The three warts which surround the 

 first abdominal stigma differ somewhat from those of the other segments. The lower 

 anterior wart is placed farther in front of the stigma than that of the other segments, 

 whilst the upper wart is placed just above the stigma and largest. The two ante- 

 rior warts of the other stigmata, however, are both placed in front, the upper one 

 farthest apart. The anterior wart of the first stigma is black, with orange tips, and 

 all other warts orange with black tip. There is a somewhat lunate, deep black 

 superior margin at base of the wart above the first stigma and a short blackish dash 

 above all other warts. The venter is of a paler gray with three large blackish spots 

 on the fourth and fifth segments. (Riley.) 



Pupa. — Body unusually thick, rather short ; surface rough aud corrugated, spotted 

 with black ; spiracles large and black. Pale dull reddish ash, dark towards and at 

 the tip of the abdomen; legs somewhat streaked with black. The tip very peculiar, 

 being short and blunt; the last segment corrugated with longitudinal ridges which 

 are swollen at the anterior edge at the suture. Cremaster broad and conical, some- 

 what flattened, the surface rough, coarsely pitted; a large smooth terminal curved 

 spine, with three pairs of lateral rather large setae, all arising near together at the 

 base of the single terminal one. Length, 20""". 



Moth. — Wings very falcate, especially in the female, where they are produced into 

 a long point. Body and wings fawn color, with scattered black dots; front of head
