154 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



1 aud came out the 19th of the same month. " It is tlierefore doable 

 brooded ia 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, lSd2, from the eggs of which larvae hatched 

 on the 9th. They went through their first moult May 15; second, May 22; third, 

 May 2G, and fourth, May 31. Pupated June 12 to 14. The moths issued from June 

 26 to July 10. Several larvae of this moth were found hy beating 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 ley's unpublished notes.)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. Oontr., 

 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 labrum 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'"™, thickness, 6™™. 



Moth. — Fore wings broad, apex pointed; male antenniB 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™™. 



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 "feeds on the over cup oak and other kinds of 

 the same genus. Some went into the ground May 30, and came out the 

 15th of June. Others that went in the 16th of October remained till 

 the 20th of April." From this it appears that in the Southern States 

 this species is double brooded. 



Larvce. — 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 pro thoracic 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 antenme. 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 in Nadata gibbosa. Segments not 

 convex, but the sutures distinct. A faint double median, whitish, somewhat broken 

 line, the two lines converging and forming one 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 end 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.
