346 THE BUTTERFLIES OF NEW ENGLAND. 



Suffused variety (Grapta marsi/as var. Edw. , Butt. N. A., ii, pi. Grapta 3, figs. 5, 6). 

 Mr. Edwards figures a suffused example raised by Mr. Barou, of Navarro, Cal. The 

 upper surface shows all the dark spots of the disc of the wings run togetlier and 

 beclouded, that on the front wings with a central fulvous patch; while the dark mar- 

 gin is T)roadened and also beclouded, at least on the front wings. Beneath, the 

 front wings have a verj'^ broad, paler band parallel to the general course of the 

 outer margin, and more or less shot with smoky brown, and darker parts beyond the 

 bands, deepest next the band, as the band is also lightest on the margins. The hind 

 wings are almost uniform with faint marbling and broadly infuscated veins, the trans- 

 verse streaks being quite obliterated. The discal silvery spot is normal. 



Caterpillar. Last stage (74:33). Head black, angular, with a spiny tubercle at 

 each of the upper angles ; body black, with a broad, greenish white, dorsal stripe, which 

 on the anterior segments is clouded with black ; on each segment, on this stripe, is a 

 fine V-shaped, black mark, having its angle at the dorsal spine; an infrastigmatal 

 greenish white line. Dorsal, laterodorsal, and infrastigmatal spines greenish white ; 

 laterostigmatal spines black; the spinules of all the spines concolorous, excepting tliat 

 those near the tip of the pale spines are blackish (adapted from Stretch). 



Mr. H. Edwards foimd in California little variation in the caterpillar, " the mark- 

 ings . . . being remarkably constant in every instance." Mr. Mead, on the contrary, 

 found much variation in Colorado. 



Chrysalis (83:41, 42). "Fawn colored, Avith a few darker markings irregularly 

 placed" (H. Edwards), especially next the inner margins of the wing covers, and on 

 the abdomen; the base of the Mings is sometimes obscurely darker than the tip, the 

 two separated by an oblique line extending from the apical Aving tubercle to the midtile 

 of the antennae, the surface being slightly angulated along this line; on the abdomen, 

 a distinct, dark, sometimes black, stigmatal band, bounded above by the upper edges 

 of the stigmata, below by the infrastigmatal tubercles, darkest beloAv and in its con- 

 tinuation on the sides of the cremaster; a slender, clearer, dorsal line, and from the 

 fourth segment backward a series of clouded oblique stripes from the laterodorsal 

 tubercles backAvard and inward ; the tips of these tubercles and all the suprastigmatal 

 series paler than the ground ; the metathoracic and first two abdominal tubercles of the 

 laterodorsal series " silver, the posterior Avitli a trace of gold" (H. EdAvards) ; mesono- 

 tal tubercle high, compressed, fully as high as broad, nearly as higli anteriorly as 

 posteriorly, and shaped generally much as in interrogationis. Fourth abdominal 

 laterodorsal tubercles regularly conical, about as high as broad, much larger than the 

 others. Ocellar tubercles conical, the curve of their separation exactly as in interro- 

 gationis. Length, 21 mm ; height at mesonotal tubercle, 8.5 mm. 



Distribution (20:1). The home of this butterfly is in the west, 

 where it ranges through the Cordilleras from CroAv's Nest (Geckles) in 

 the north to New Mexico (Edwards) in the south, and from the eastern 

 foothills, — Clear Creek and Platte Canons, Col. (SnoA\^) — to the Pacific; 

 along this coast it is recorded from Santa Clara Co. (Stretch) and Men- 

 docino Co., Cal. (Baron, Butler) to Oregon and San Juan and Vancou- 

 ver's Islands (H. Edwards). Within recent years it has been discovered 

 also in the east, first by T. L. Mead, who recognized it at sight from his 

 acquaintance with it in Colorado, and Avho captured a pair of s})ecimens 

 (the only ones seen in a month's collecting) in July, 1874, at Cameron 

 Lake, a little north of Port Hope, Ont. ; next a couple were raised by 

 C. W. Pearson in June, 1875, from caterpillars taken at Chateauguay 

 Basin, fifteen miles south of Montreal, where J. G. Jack has since taken 

 a specimen ; Mr. Fletcher has also found it at Ottawa, and lastly a single
