208 LEPIDOPTERA. 



rich velvety green, with a j^ellowish tinge, slightly paler be- 

 tween the segments, and a dorsal stripe of a darker shade, 

 centred along the middle segments with a faint, yellowish 

 line. The anterior edge of the second segment is yellowish 

 brown, with a few dots of a darker color. The body is thickly 

 covered with minute hairs which are brown above and white 

 below, being scarcely visible to the naked e3^e. The body is 

 flattened above (dorsal crest not bordered with yellow as in T. 

 Acadica), steeply sloped at the sides, where it is striped with 

 faint oblique lines of yellowish, two or three on each segment. 

 The two last segments have a patch of yellowish on each side, 

 making the dark dorsal line appear much more prominent. A 

 faint j-ellowish line close to the under surface from the fifth to 

 the terminal segments. The under surfoce is bluish green, 

 with a darker patch on the last two segments. 



"The chrysalis changed June 19tli, and is nearly oval in form. 

 The head-case is rounded, and the body is dark reddish brown, 

 with black markings thickly covered with fine, short, whitish 

 hairs, rather more numerous on the anterior and posterior 

 segments. Anterior segments with man^' thickly set patches 

 of blackish, and a dark ventral line from the sixth to the 

 twelfth segments. It is bound by a few silken threads on 

 the anterior portion of the seventh segment." 



The accompanying cut (Fig. 197) represents the pupa of a 



Thecla, found in July bj' Mr. Sanborn, on the Glen road to 



Mount Washington. The body is smooth and tapers gradually 



from the mesothorax, and the venation of the wings is 



§very apparent. Another pupa, probably T. niphon, found 

 by Mr. Sanborn, is very different, being much stouter, 

 and thicker through the abdomen, by a third of its 

 Fig. 197. (jj.^jj^y^gj.^ i^Ijj^j^ ii^Q chrysalis figured. It is rough and 

 covered with short, fine, stiff hairs ; the tegument is so thick, 

 that there are no traces of the veins of the wing, while the 

 sutures between the segments and the appendages are not 

 nearly as distinct. The larva, according to Mr. Sanborn's 

 notes, was found feeding upon the White Pine, July loth. 

 "It was .45 of an inch long; the head was retracted, yellow- 

 ish, and the body pale, transparent green, Avith four longi-
