the apex; var. timandra has sordid white fore wings, with distinct lines, hind wings 
with the median band narrow ; var. hero has the fore wings with a large white spot 
at base; and in var. gisela the fore wings are black to the transverse posterior line.

240. Catocala similis Edwards. 
The transformations of this moth were first described by Abbot and 
Smith, who named it G. amasia. Its food-plant is the oak. 
Larva. — Probably nearly the same as in C. amasia, thus deceiving Abbot in the 
identity of the two species. His figure makes it greenish gray, with protuberances 
on each segment, and with dorsal, subdorsal, and stigmatal dark lines ; also an oblique 
dark line on each segment. (Hulst.) 
Moth. — Fore wings gray, clouded with brown and black ; lines distinct ; transverse 
anterior line edged inwardly ; transverse posterior line edged outwardly with brown, 
and angulated with an angle beyond the reniform spot in place of the M-shaped part 
of the line, then nearly straight to the sinus, which is very small; reniform spot 
pyriform, light; subreniform annulate ; triangular light patch at apex, along costa ; 
hind wings bright yellow ; median band curved, nearly even, short, border broken. 
Expands 45 to 55 mm . From East and South. 
Var. aholah has the fore wings clear silver gray, with a large black patch beyond 
the reniform extending to the apex. 
Var. Isabella has dirty white fore wings, lines distinct; transverse posterior line 
edged with cinnamon brown. (Hulst.) 
241. Catocala chelidonia Grote. 
According to Mr. Doll the food-tree of this Arizona species is the 
scrub oak. 
Moth. — Fore wings even dark gray, somewhat hoary ; reniform spot shaded with 
gray ; subreniform spot stained with brown ; lines indistinct, having the same course 
as C. similis. Hind wings like those of C. similis, but with the median band gen- 
erally narrower. Probably representing C. similis in Arizona. Expands 40 to 50 mm . 
242. Catocala amasia (Abbot and Smith). 
The caterpillar is said by Hulst to be probably similar to that of C 
similis aud to feed on the oak or pride of India. 
Moth. — Fore wings sordid white ; basal half line very distinct ; transverse an- 
terior and posterior lines nearly obsolete, the latter, when evident, scalloped, not 
angulated ; median space sordid white ; reniform spot blackish ; transverse posterior 
line edged outwardly with cinnamon brown ; subterminal line evenly dentate. 
Hind wings yellow; median band often hooked; the border generally interrupted. 
Expands 50 to 55 mm . Eastern and Southeastern United States. (Hulst.) 
243. Catocala deUlah Strecker. 
According to Mr. Hulst, the caterpillar of this moth feeds upon the 
oak, but no description of it has yet been published. The larva of var. 
desdemona, which inhabits Arizona, was reared by Mr. Doll from the 
scrub oak. 
Moth. — Fore wings rich velvety yellow-brown; basal dash present ; transverse an- 
terior line very heavy and dark ; transverse posterior line dark aud distinct; teeth 
prominent and broad; subterminal space somewhat lighter; subterminal line fine,
