This common species is very similar in general type of maculation to flebilis and vidua, being in size intermediate 

 between the two; the reniform is generally more filled with brown than in vidua and the rather prominent black shade 

 through the submedian median fold of this latter species is lacking, a feature that is not very well brought out in the illus- 

 tration (PL II, fig. 11) but is better seen in Holland's figures (PL xxi, figs. 5 and 8). The form luctuosa (Figs. 19 and 20) 

 is characterized by the purplish-brown ground-color of the primaries. The species is quite constant in maculation and 

 shows no sexual differences. The larva, which is quite distinct from that of vidua, is closely approached by that of residua, 

 differing in the presence of lateral filaments. 



The species extends throughout practically the whole of the eastern half of the United States, ranging northward into 

 Ontario and Quebec. 



Catocala dejecta Strecker 

 Plate II, fig. 8; PL XVIII, figs. 39 and 40 (claspers). 

 Catocala dejecta Strecker, 1880, Bull. Brooklyn Ent. Soc, II, p. 97. 



This species is not common. It is allied to retecta and vidua but has more pointed wings and a rather prominent 

 white costal patch before the reniform, the remainder of the wing in the male being unicolorous gray; the female (Fig. 8) 

 is rather more contrasted in maculation, with a short, black, basal dash. The early stages are unknown. The species 

 appears to have the usual range of the hickory-feeders, being reported from various states of the Ohio and Mississippi 

 valleys and from the Atlantic Coast States from New Hampshire to Virginia. 



Catocala insolabilis Guenee 



Plate I, figs. 7 and 8; PL X, fig. 23 (larval head); PL XII, fig. 11 (larva); PL XIX, figs. 1 and 2 (claspers). 



Catocala insolabilis Guenee, 1852, Hist. Nat. Spec. Gen. Lep., VII, p. 94. Beutenmuller, 1903, Bull. Amer. Mus. Nat. Hist., XIX, 

 p. 509 (larva). 



This species is easily recognized by the dark shading along inner margin of primaries and by the practical lack of the 

 white median band on the under side of both wings. 



The only knowledge of the early stages that we have is Beutenmuller' s note on the mature larva, figure 11 of plate 

 XII presumably being based on the original of this description. 



The species is wide-spread over the same general area common to all the hickory-feeders. 



Catocala vidua (Abbot and Smith) 



Plate I, fig. 17; PL XIII, fig. 6 (larva); PL XV, fig. 1 (larval head); PL XV, fig. 32, and PL XVII, 

 fig. 12 (segments); PL XIX, figs. 3 and 4 (claspers).

Catocala vidua Barnes and McDunnough, 1918, Bull. Amer. Mus. Nat. Hist., XXXVIII, p. 155. 



Catocala desperata Guenee, 1852, Hist. Nat. Spec. Gen. Lep., VII, p. 95. French, 1888, Can. Ent., XX, p. 28 (larva). 



This species is one of the largest of the black-winged forms; its points of distinction from allied species have already 

 been pointed out. The figure of the larva given by Abbot on his plate xci is certainly not that of vidua but is probably 

 that of ilia, the fact that it is stated to be an oak-feeder being a further proof in favor of this association. 



Vidua, as already noted by us, is one of the few species in which the larva has seven stages, probably due to the small 

 size of the egg and the large size of the moth. 



The species is rather common and wide-spread throughout the eastern half of the United States and extends into 

 southern Ontario.
