174 FIFTH REPORT OP THE ENTOMOLOGICAL COMMISSION. 
3, Catocala arnica (Hiibner). 
Mr. Ooquillett found two caterpillars of this moth (C. androphila 
Guen.j id Illinois on a burr oak tree June 5. They spun cocoons about 
disclosing the moths July 24. Abbot also figured in manuscript the 
July .'3, caterpillar, which he found on the oak. 
Larva, — Body slender, doll greenish yellow, s light dorsal stripe, <>n each side of 
which is a darker stripe, on which is a row of black piliferous spots; a stigmatal 
row of black piliferous spots J on top <d' segment 8 is a slight prominence; underside 
of body greenish white, with a row of black spots in the middle; one spot to each 
segment; the two anterior pairs of abdominal legs smaller than the two posterior 
pairs. Head gray, with two white spots on the upper part of the face. Length, 1£ 
inches. (Coqoillett). 
Moth. — Pore wings pale gray, the lines fine, not very evident, the transverse ante- 
rior hue the heavier marked. A distinct black median shade on costa above the 
re ui form and continued beneath it, running upward to external margin below apex. 
A brown shade fills the space left by the exserted portion of the transverse posterior 
line beyond the reniform. This black median shade is marked on costa, but else sub- 
obsolete in all the males I have before me, and the brown shading very faint. The 
transverse posterior line minutely dentate without prominent teeth. Subreniform 
small, pale, and both spots inconspicuous and often incompletely ringed. The ser- 
rated subterminal white shade is tolerably distinct ; fringes dark. Hind wings bright 
yellow; a broad thick terminal band is squarely discontinued and appears as a black 
dot at anal angle. Friuges dark except at apex, where is a small yellow patch. 
Beneath the marginal band is brokenly and narrowly continued to anal angle, and 
the median band is indicated by tolerably large spots or fragmeuts. A specimen 
from Texas differs by its dirty, ocherous gray primaries much shaded with deep 
black, and may be a distinct species. Expanse 40 to 45 mm . (Grote). 
239. Catocala micronympha Guende ( C. fratercula G. & R.) 
Order Lepidoptera; family Noctt:id.e. 
The caterpillar lives on the live oak iu early spring in Florida, the 
insect remaining in the pupa state two weeks (A. Koebele, Bull. Brook- 
lyn Ent. Soc. i, p. 44. It also feeds on the burr oak in Illinois. 
According to Coquillett it spun its cocoon June 1, disclosing the moth 
Juue 28 (Papilio, i, 7). 
Larva. — Body ashen gray, the dorsal space dark gray, and on its outer edge is a row 
of black piliferous spots; on top of seguieut 8 is a conical dark-gray projection, 
tipped with whitish; posterior part of segment 8 blackish; body beneath pale green- 
ish white, with a row of black spots in the middle, one spot to each segment ; the two 
anterior pain of abdominal legs are much smaller than the two posterior pairs; head 
light gray, bordered on the top and sides with black. Length, If inches. 
Moth. — Of moderate si/e. varying in the distinctness of the median black shade, 
which ascends as usual to the external margin. The median space is sometimes 
shaded with whitish before the reniform spot. There is no sinus to the trane 
posterior Line. The shape of the median band varies in being more or less acutely 
produced opposite the anal constriction of the hind border. The fore wings vary in 
depth of color. Expanse of wings. A! to 46 Bam . Rhode Island to West Virginia.

This moth is very variable; var. atarah is slightly lighter than the type form : var. 
faquenetta has olivaceous fore wings with indistinct lines, and a dark shading toward
