OF NORTH AMERICA. 63 



Walker, in which the dark coloring most largely predominates, and 

 the Callimorpha vestalis, Packard, where all the markings on the pri- 

 maries are obsolete. This variety is the Callimorpha mililaris, Harris, 

 (plate 2, fig. 20.) 



3. ?. — White and brown. Head fulvous; palpi fulvous; tips brown, 

 Prothorax pale fulvous with two brown dots near the median line. 

 Thorax brown, with two lateral white stripes. Abdomen whitish, with 

 a narrow dorsal brown line. Thorax beneath pale fulvous, legs the 

 same, outside of the tibiae and femora of the two anterior pairs brown. 



Anterior wings while, marked with brown. A brown stripe on the 

 inner margin below the submedian vein, which throws off an oblique 

 transverse band across the nervules, its inner edge terminating at the 

 apex. Outer edge brown nearly to the anal angle, thus enclosing a 

 large ovate patch of while, supplemented near the apex by a small 

 white spot. Costa above the subcostal vein, brown nearly to the apex, 

 with two angular projections directed backwards, one terminating at 

 the origin of the first median nervule, the other about midway betw^een 

 it and the apex. There are generally corresponding, but less promin- 

 ent projections, on the oblique band. Posterior wings white immacu- 

 late. 



Beneath as above, except that the markings of the primaries are 

 quite obscure, while the costa and apical portion of the oblique band 

 have a yellowish tinge. 



Expanse of ivittgs, r.8o inches. Length of body, 0.70 inch. 



Habitat. — Canada and Eastern United States. Canada, (.Saunders.) 

 New York, (Edwards.) Mass., (Sanborn.) Delaware, (Doubleday.) 

 St. Louis, (Agassiz.) (Coll. generally.) 



Considering this form (pi. 2, fig. 20,) as the type, all the other modi- 

 fications can be derived from it, either by the expansion and confluence 

 of the brown markings, or by their obsolescence being more or less 

 complete. In C. fidvicosta, Clemens, the markings are all obliterated 

 on the anterior wings. Plate 2, fig. 21 shows a variety in which the 

 oblique band only is obliterated. By the union of the toothed projec- 

 tions of the brown costal margin with those of the oblique band, the 

 wings become five-spotted and we have C. Lecontei, Boisduval. By 

 continuing this expansion of the brown markings we get successively 

 C. coniigua and C. cotifinis of Walker. Not having seen the two last 

 mentioned varieties, I have included them as synonyms on the author- 

 ity of Grote, who has compared the originals in the British Museum, 

 (Trans. Am. Ent. Soc, vol. 2, p. 72.) Some forms here classified as vari-
