The typical form of this species is the dark one figured on plate I, figures 9 and 13; the form which for a long time 

 was erroneously considered to be typical has been named clara by Beutenmuller (Fig. 11); bianca Hy. Edwards is a syn- 

 onym of the typical form; and phrynia Hy. Edwards (Fig. 10) is the form with even gray primaries. Elda Behrens (Fig. 

 12) was described as a good species from Portland, Oregon, but is at the best a mere geographical race found on the Pacific 

 Coast from British Columbia to Oregon; it is distinguished by its very dark primaries (darker than phrynia) and narrow- 

 banded secondaries, the band usually showing traces of violet shading; it is apparently best defined on Vancouver Island, 

 B. C, for specimens before us from the interior of Washington State can scarcely be separated from phrynia. 



The species is a near ally of the European fraxini Linnaeus and the relationship is clearly shown in the larvae, which 

 are extremely close. Clark, in his otherwise excellent account of the larval stages, has omitted one of the molts; this is 

 rectified by Rowley and Berry, our own breeding experiments verifying their statement that there are five molts. 



In the northern woods of Manitoba, Ontario, and Quebec the species is quite common and extends through the New 

 England States into New York, New Jersey, and Pennsylvania. In the Middle West it occurs in the border states but 

 has not been reported south of northern Illinois and Iowa. Snow records it from Idaho Springs, Colorado, and we have 

 a single specimen before us of the form clara from Provo, Utah. In the southern portion of its area of distribution it is 

 scattered and rare, being distinctly a northern species. The race elda, as already noted, occurs in the northern Pacific 

 States. 



Catocala marmorata Edwards 



Plate III, fig. 19; PL XIX, figs. 27 and 28 (claspers). 



Catocala marmorata Edwards, 1864, Proc. Ent. Soc. Phil., II, p. 508. Strecker, 1874, Lep. Phop. Het., 73, PL ix, fig. 6. 



The original description states that Yreka, Siskiyou County, California, is the type locality of this striking species 

 but we imagine this to be an error. Strecker's figure is drawn from the type specimen, which at that time was in the 

 collection of the Academy of Sciences, Philadelphia; at the present time it is misplaced or lost, Edwards having probably 

 never troubled to place a type label on the specimen, as is the case with so many of his diurnal species. Fortunately, 

 Strecker's figure leaves no doubt as to the identity. 



The species is wide-spread but everywhere rare and nothing is known of its early stages. It extends along the Atlantic 

 Coast from Vermont to North Carolina and westward through the Ohio Valley to Missouri; it has also been recorded 

 from southern Ontario and Wisconsin. 



Catocala parta Guenee 



Plate III, fig. 14; PL X, fig. 34 (larval head); PL XI, fig. 4 (larva); PL XIII, fig. 10 (larva); PL XX, 



figs. 1 and 2 (claspers).

 Catocala porta var. perplexa Strecker, 1873, Lep. Rhop. Het., p. 38, PI. v, fig. 11. 

 Catocala parta var. petulans Hulst, 1884, Bull. Brooklyn Ent. Soc!, VII,' p. 43. 



This species is fairly constant in maculation and may be known by its pale gray primaries and salmon-colored 

 secondaries. Perplexa Strecker is a form with rather darker ground-color of primaries and an obliqne white area from 

 costa to subremform; petulans Hulst was based on a specimen with yellowish secondaries.
