INSECTS INJUKING OAK-LEAVES. 175 



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. 

 (Hulst.) 



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 liue on each segment. (Hulst.) 



Moth. — Fore wings gray, clouded with brown and black ; lines distinct ; transverse 

 anterior line edged inwardly ; transverse posterior liue edged outwardly with brown, 

 dud angulated with an angle beyond the reniforui 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 ; 

 hiud wings bright yellow ; median band curved, nearly even, short, border broken. 

 Expands 45 to 55"™. 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. isahella has dirty white fore wings, lines distinct; transverse posterior line 

 edged with cinnamon brown. (Hulst.) 



241. Catocala cheiidonia 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. Hiud wings like those of C. similis, but with the median band gen- 

 erally narrower. Probably representing C. similis in Arizona. Expands 40 to 50™"*. 



242. Catocala amasia (Abbot and Smith). 



The caterpillar is said by Hulst to be probably similar to that of G. 

 similis and 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 ; subtermiual liue evenly dentate. 

 Hind wings yellow; median band often hooked; the border generally interrupted. 

 Expands 50 to 55""™. Eastern and Southeastern United States. (Hulst.) 



243. Catocala delilah 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 bj^ 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 liue dark and distinct; teeth 

 prominent and broad ; subterminal space somewhat lighter; subterminal line fine,
