8 BARNES AND McDUNNOUGH: CATOCALA 



Catocala ccelebs Grote 

 Plate VII, fig. 8; PI. XVIII, figs. 13 and 14 (claspers). 

 Catocala coelebs, Grote, 1874, Trans. Amer. Ent. Soc, V, p. 96. 



This species may be distinguished from badia, with which it has been at times confused, by the pale gray color of the 

 median area of the primaries and the brown basal and postmedian shading. 



Nothing is known of the early stages or food-plant of the larva. 



It is a northern species and generally rather rare, although in certain districts of Maine it is apparently quite com- 

 mon. It occurs in Ontario and Nova Scotia and probably will be found in Quebec, although not mentioned by Winn in 

 his List of Quebec Lepidoptera; it extends southward through New Hampshire to the Adirondack Mountains of New 

 York.

 Catocala badia var. phoebe Hy. Edwards, 1885, Papilio, IV, Jan., p. 125. 



This species is rather distinctive on account of the general indefiniteness of the maculation of the primaries, which 

 are more or less suffused basad of the t. p. line with purplish brown. The figure (PI. VII, fig. 16) shows the maculation 

 rather more distinct than usual and apparently represents a transition to the form phoebe Hy. Edwards, which was de- 

 scribed from New Hampshire specimens and in which the t. p. line (normally straight) is sharply angled outwardly opposite 

 the cell. Whether phoebe will prove to be a good geographical race or merely an aberration must remain undecided until 

 more material is forthcoming. 



The larva is unknown to us. Beutenmuller figures several varieties (PI. XII, figs. 2-6) but, as already stated, has 

 confused the larvae of this species with those of muliercula and careful breeding will be necessary to clear up the matter. 



The species is common in the southern New England States and the northern Atlantic States. 



Group V 



Egg flat, disk-shaped, with slightly elevated rim. Larva without dorsal elevations or lateral filaments. Male 

 claspers somewhat asymmetrical, the left clasper being more heavily chitinized dorsally and blunter at the apex than the 

 right one; both apices project well beyond the thinly chitinized ventral area of the clasper. 



This group includes a number of species in which the male genitalia are so similar as to be practically useless as a 

 means of specific separation, especially as considerable variation is shown in individuals of the same species. The flat egg, 

 of a highly specialized nature, is very characteristic. As a rule, there are five larval molts but there may occur as many 

 as seven, as is the case with habilis. The larvse, as far as is known, are all hickory- or walnut-feeders. The species serena, 

 denussa, agrippina, and sappho are only tentatively placed here, as nothing is known of their early stages. There is a 

 marked tendency in the group for the females of the species to develop a basal dash on the primaries, notably the case 

 in habilis and angusi where they are seldom without it.
