32 BARNES AND McDUNNOUGH: CATOCALA 



Catocala concumbens Walker

Catocala concumbens var. diana Hy. Edwards, 1880, Bull. Brooklyn Ent. Soc, III, p. 57. 

 Catocala concumbens ab. hillii Grote, 1883, Papilio, III, p. 43. 



The figure gives an excellent idea of this species; diana is an aberration with pink suffusion on the abdomen dorsally 

 and hilli a color form in which the secondaries are yellow; this latter variety may have been produced artificially, although 

 its occurrence is possible. 



This common species is much more northern in its range than cara, its southern boundary being, roughly speaking, 

 the Ohio Valley region; in the north it extends through Quebec and Ontario into Manitoba and has been reported by 

 Mr. Arthur Gibson from as far north as Fort Selkirk, Yukon Territory. We know of no authentic records from the Rocky 

 Mountain region or the Pacific Coast. 



Catocala amatrix (Hiibner) 



Plate III, figs. 11-13; PL X, fig. 36 (larval head); PL XI, fig. 3 (larva); PL XXI, fig. 10 (clasper).

Catocala nurus Walker, 1857, Cat. Lep. Het. Brit. Mus., XIII, p. 1195. 



Catocala selecta Walker, 1857, Cat. Lep. Het. Brit. Mus., XIII, p. 1197. 



Catocala editha Edwards, 1874, Trans. Amer. Ent. Soc, V, p. 112. 



The typical form, as far as can be judged by Hiibner's figure, is the one with dark streaks from the base to below 

 .the apex of the wing, as represented in plate III, figure 11; nurus Walker is a synonym. The pale form without dark 

 shades has been named selecta by Walker and is figured on plate III, figure 12. Both forms are equally common. 



The Rocky Mountain form, to judge by five specimens before us, has the primaries much paler in color than in the 

 eastern and southern specimens and apparently represents a good geographical race to which we imagine the name editha 

 must be applied, the type of this species being from Arizona. The form of editha corresponding to selecta Walker has been 

 named pallida Poling and the type from Denver, Colorado, is before us, but this name, although included in Smith's Check 

 List, has not to our knowledge ever been published; the form is figured on plate III, figure 13. 



The species is common and wide-spread, occurring throughout practically the whole of the United States, east of the 

 Rocky Mountains, and extending north into Quebec, Ontario, and South Dakota. In the Rocky Mountains of Colorado 

 and Arizona the race editha seems rare; we have a few specimens from the vicinity of Denver. 



Group XII 

 Male claspers more rounded apically and less asymmetrical than in Group X. Early stages practically unknown. 



Of the species included in this group, the life-history of only desdemona is known to us; we are, therefore, unable to 

 define the group definitely and we place them provisionally together on account of general similarity of maculation in 

 the adults, combined with close resemblance in the male claspers. The larva? will probably all feed on oak, as is the case 

 with desdemona.

The typical form from Texas (PL VI, fig. 13) has considerable brown suffusion over the primaries; we have not seen 

 a long enough series to determine whether or not this feature is constant. In Arizona and Utah we meet with a race,
