Moth. — Head gray, vertical tuft above black. Thorax reddish brown, patagia blackish above, 
distinct line oii the prothorax. Primaries reddish brown, nervxiles black. Base of the costa 
dark, beyond cinereous with brown scales along the edge, which become indistinct waved lines 
continued across the wing and are more oblitpie beyond the discal dot. One of these scalloped 
lines two-thirds of the way from the base of the wings to the discal spot is more distinct than the 
others, with a distinct scallop in the discal space. The line«ar reddish brown discal dot is 
surrounded hy gray, and below and beyond is a dark, rather broad discoloration curved around it. 
Beyond this the black nervules are interrupted by gray scales. There are two obscure series of 
reddish dots near the margin in the interspaces. Opposite the outer series of these spots the 
fringe, otherwise ferruginous, is of a duty white. Secondaries sordid white, discolored with 
smoky brown at inner angle. The large tuft beneath the head is lilac-ashen. Beneath, the fore 
wings are white, smoky in the middle. Gosto-apical dots distinct. Fringe white, black at the 
ends of the nervules; at the base are white dots in the interspace. Secondaries entirely white, 
exce])t the dusky spot on the inner angle. Legs ashen, ends of the scales dark, tarsi broadly 
annulated with dark. Abdomen slender, whitish, a narrow mesial line beneath. 
In the female the mai'kings are more distinct. The two series of ferruginous xvaved or scal- 
loped lines on each side of the median region are more distinct. The submarginal ferruginous 
region is more broken up by ashen scales. The secondaries and abdomen above smoky brown, 
with a pale mesial didiise band ending on the inner edge in a diffuse, obli<pie, sordid, whitish baud, 
bordered on each side by sordid white. There are faint traces of a slight mesial fascia across the 
wing. Beneath, both wings are dark smoky, xV light ferriigiuons line on the abdomen, which is 
itself larger than in the other species. Expanse of wings, male, 3.5-43 mm.; female, 40 mm. 
Length of body, male, 17-24 iniu.; female, 20 mm. 
Cwto(lasi/.H cinereo/rons Pack., as stated by Grote, is undoubtedly a variety of this species, now 
to be referred to the genus Schizura. It differs in the costal region of the fore wings, except at 
the base, being ash-gray, with a slight lilac tint; the inner edge also being grayish, the middle of 
the wing from the base to the outer edge beiiig dark brown. The following notes on the larva of 
this variety were received from Professor Biley, and ixublished in our Eeport on Forest Insects, 
1800, p. 155: 
June 20, found on oak two very small larvre, wliich entered the ground July 8 and emerged as moths July 30. 
Color of larva as follows: Second aud third segments grass-green ; the horn of the fourth segment is hiforke.d and 
the tips blood-redj also the tips of the two smaller horns on joints 8 and 11. The rest of the body and head reddish- 
brown. 
*8". telifer (Grote) is only a variety of S. ipomew^ with two long, distinct, black streaks, one 
passing through the discal spot and the other extending along the snbmedian vein. 
The eggs were kindly sent me by Miss Emily L. Morton, who obtained them at Kewburg, 
N. Y., from a female t^cMzara ipnmew {CdclodaHyn hiyuttata Pack.) of the normal form mated with 
a male of the variety C. cinercofrons Pack. Miss IMorton informed me that a male of the normal 
C.bifjutiata was also attracted. The eggs were laid July Hand hatched July 17; the first molt 
occurred July 19-24; the second on August 1-2; the third August 0-7 ; the fourth August lG-18; , 
the date of the last molt not noted, but about four or five days later. 
Egg . — Giie mm. in diameter. Perfectly hemispherical in shape, with the surface marked on 
the sides and near the base with minute polygonal areas which toward the top become gradually 
smaller, with minute beads at the angles; the top of the egg is smooth. 
First stage, larva just hatched, — Length, 2-3 mm. It shows an approach to the characters of 
the fully fed larva in the niilifted small anal legs and the tubercles on the segments, though those 
chai'acteristic of the last stage are not specialized. 
The head is enormous in proportion to the size and width of the body, being twice as wide as 
the thoracic segments; it is well rounded, rather short antero-x)osteriorly; full and rounded on the 
vertex, rounded, hot angulated, above, aud in color dark amber.
