154 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
1 and came out the 19th of the same month." It is therefore double 
brooded in the Gulf States and single brooded in the North. The fol- 
lowing notes on its habits have been given by Professor Riley: 
A pair of this moth were taken May 2. 1882, from the eggs of which larvae hatched 
oil the 9th. They went through their first moult May 15; second, May 22; third, 
M;iv 26, and fourth, May 31. Pupated June 12 to 14. The moths issued from June 
26 to July 10. Several larvai of this moth were found by heating on oak June 26, 
July 10, 1882. This larva is now very plentiful and of all sizes, on several oaks. (Ri- 
ley's unpublished notes.) 
Dr. Lintner has bred the moth from a larva found feeding on the 
maple in New York. The figure on Plate XI was kindly loaned by 
him, and is probably the original of the wood-cut in his Eut. Coutr., 
iii, 150. 
Larva. — Body green, large, head very large, full, rounded, high towards the ver- 
tex, as wide as the body, deep pea-green; the labruin whitish green; mandibles 
bright yellow, tipped with black, making them very conspicuous. Body glaucous 
pea-green, thick, full, soft, tapering towards the end, and the surface with minute 
raised, flattened, more or less confluent granulations. A lateral yellow line formed 
of coarse yellow, raised, flattened areas. Spiracles deep red. Supra-anal plate con- 
ical, flattened, apex much rounded, the edge colored bright yellow. Thoracic and 
abdominal feet pale pea-green ; all concolorous. Length, 33 mm , thickness, 6 mm . 
Moth. — Fore wings broad, apex pointed; male antenna? pectinated to the end. 
Body and wings reddish, reddish yellow-brown ; thorax with a high, large, loose 
crest. Fore wings with two white twin discal dots, rather widely separated. An 
inner and outer narrow, oblique reddish-brown line ; the outer parallel with the outer 
margin of the wing, which is slightly scalloped. Fringe dark, the scallops filled in 
with white. Hind wings whitish, with a faint outer line. Beneath, uniformly 
whitish ; a faint outer line common to both wings ; the costal edge dusted with red- 
dish-brown. Abdomen yellowish-brown. Expanse of wings, 48 mra . 
212. Lophodonta angulosa (Abbot and Smith.) 
It occurred on Quercus alba October 7, at Providence, when it began to 
pupate, the moth appearing the following June. Abbot and Smith re- 
mark that in Georgia it u feeds on the over cup oak and other kinds of 
the same genus. Some went into the ground May 30, and came out the 
loth of June. Others that went iu the 16th of October remained till 
the 20th of April." From this it appears that in the Southern States 
this species is double brooded. 
Larvae . — Somewhat like Nadata gibbosa, but the head is smaller, and it has no such 
supra-anal plate, while the body is smooth, not granulated. Head nearly as wide as 
the prothoracic segment, but not so wide as the body; full and rounded; though a 
little flattened above, deep pea-green, but concolorous with the body. On the side a 
pink line edged above with white extending to base of the antennae. Mandibles green 
at base with an orange-red line along upper edge; tips black. A short black line 
above at base of antennas. Body noctuiform, tapering towards the anal legs, which 
are short and small, no larger than the other abdominal legs, supra-anal plate small, 
rounded at the end, not large and conspicuous as iu Xadata gibbosa. Segments not 
convex, but the sutures distinct. A faint double median, whitish, somewhat broken 
line, the two lines converging and forming oue on the middle of the supra-anal 
plate and tinged slightly with pink. A distinct lateral pink line begins on the side of 
the head and extends to the eud of the body along the edge of the supra-anal plate. 
The line is somewhat finely bordered with brown, and is edged below with white.
