1918 THE BUTTERFLIES OF NEW ENGLAND. 



nearly reaches the apex of the wing) ; the distance between the tips of the second and 

 third veins is a little longer than that between the third vein and the apes of the wing ; 

 the elbow of the fourth vein without stump of a vein (a very minute one in one of the 

 specimens) ; the great cross-vein oblique, parallel to the last section of the fourth 

 vein ; small cross-vein (in most specimens) opposite to about the middle of the dis- 

 tance between the tips of the auxiliary and first vein. Length, 7 mm." 



[The following description of the early stages was taken from the living specimens : 

 — Larva yellowish wliite, tapering anteriorly and armed with a double curving black 

 hook ; blunt posteriorly and furnished with a pair of lilack circular warts each hollowed 

 and iiaving the annular ridge thus produced elevated into three slight prominences. 

 Length, 13 mm. ; breadth, 4 mm. ; height, 3.25 mm. 



The pupa case is short and thick, bluntly and equally rounded at either end; at the 

 posterior extremity are two minute warts scarcely raised above the surface; on either 

 side are two distant irregular rows of nearly continuous, longitudinal punctures; at 

 the posterior end of each segment, occupying nearly one-third of it, is a band of minute 

 raised points arranged to a certain extent in diagonal rows; the remainder of the sur- 

 face is finely striated with transverse lines and also marked by shorter impressed lines, 

 radiating from points on either side either connected with the two longitudinal rows 

 of punctures or lying between them. The color is very dark reddish black, almost 

 piceous. Length, 8.76 mm. ; breadth, 4.4 mm. s. h. s]. 



"Bred from Vanessa atalanta (T. W. Harris and S. H. Sciidder)." 

 Several bred sjiecimens sent me by Mr. Scudder and others collected in the 



vicinity of New Haven, agree well with the type specimens of Osten Sacken ; 



the only differences that I would note are included within the brackets. 



Very characteristic of the species is the changing spot on the sides of the 



face below the antennae.

"ilfaZe.^Distribution of the frontal bristles as in E. futilis ^, that is, on each side, 

 beginning with the vertex, three longer bristles pointing backwards, three shorter 

 bristles before the antennae, and three or four bristles descending on the face, along- 

 side the antennae. On the ocellar triangle a pair of bristles pointing forward. Be- 

 tween the row of frontal bristles and the eyes, a few scattered microscopic hairs ; 

 sides of the face bare. Front, face, and posterior orbit silvery white. Frontal stripe 

 brown, rather narrow, enclosing posteriorly the grayish ocellar triangle. Antennae 

 black, slightly tinged with brownish red on the first two joints ; the third joint is very 

 long, almost reaching the edge of the mouth. Only a few shorter bristles above the 

 usual long, oral bristle. Palpi reddish yellow. Eyes pubescent. Thorax gray, with a 

 slight yellowish tinge from an oblique point of view ; two slightly divergent black 

 lines do not reach beyond the middle ; two lateral black stripes are interrupted at the 

 suture and prolonged beyond it to the hind border, these lateral stripes are broad- 

 est in the middle and end in a point, anteriorly and posteriorly. Scutellum gray; 

 two [larger and a smaller] macrochaetae on each side, a third intermediate, very 

 small pair on the apes. Abdomen gray, with a slightly yellowish tinge, especially on 

 the last segment ; somewhat marmorate, with blackish cross-bauds on the hind mar- 

 gins of the segments, and a longitudinal blackish line; the cross-bands appear more 

 distinct and broader from an oblique point [of view ; the longitudinal line disappears 

 when viewed sideways from above. A pair of macrochaetae on the hind margin of the 

 first segment; two pairs on the second segment, one in the middle, the other on the 

 hind margin ; on the third segment a pair in the middle, and the usual row on the hind 

 margin; two rows on the fourth segment. Legs, coxae and femora reddish; tibiae
