1358 THE BUTTERFLIES OF NEW ENGLAND. 



on either side reaching from the apex to the outer edges of the labrum and two 

 other similar ones extending from near the apex along the liinder edge of the head t(^ 

 the under surface but not meeting at either end; triangle excepting the edges, black; 

 and l)etween this and the lirst mentioned band the head is lemon yellow; ocellar field 

 black; antennae white, dusky at tip. Body pea-green marked with black ; every seg- 

 ment excepting the first thoracic is margined broadly at the anterior extremity with 

 black, narrowing on the sides and seldom extending much upon tlie under surface; 

 across the middle of all the segments, excepting those atthe two extremities, is a broad, 

 transverse, black belt, generally situated midway between two consecutive Ijlack 

 margins and occupying above nearly half the space betw-een them ; on the eighth ab- 

 dominal segment the belt is placed close to the posterior border ; the anterior border 

 of this belt is very irregular, little rounded, lemon colored pits, often more than half 

 the depth of the band, being hollowed out along a laterodorsal and lateral line, the 

 latter becoming supr.alateral on the thoracic segments ; there are also similar but larger 

 suprastigmatal pits, deeper tliau the others and hollowed out from the posterior 

 border of the belt, with the lateral pits causing the lower portion of the belt to form a 

 large S-shaped band ; or broader than the others and hollowed like them from the an- 

 terior border, on the thoracic segments; on the abdominal segments the entrance of 

 the latter pits is occasionally closed so as to leave a lemon colored spot in the centre 

 of the black belt; the first thoracic segment has the central belt but it is entire and in 

 front of the osmaterial orifice are three short, moderately broad, longitudinsil bars, 

 one median, the other at either extremity of the orifice; the anterior fold of the ninth 

 abdominal segment is bordered posteriorly by a broad, transverse stripe, interrupted, 

 at least in front, subdorsally ; at the anterior limit of the portion behind is a trans- 

 verse equal stripe, extending just beyond the limits of the laterodorsal line, and behind 

 this is an inclined, transverse, irregular stripe, starting from close to the anterior base 

 of the segment and crossing its most elevated hinder portion; there is also a ventro- 

 stigmatalrowof rather large, round, black spots, two each on the first to eighth abdom- 

 inal segments, confluent on the seventh and eighth. Beneath, the body is greenish 

 white with a ventral black spot in the middle of each segment. Body covered 

 with exceedingly short, delicate, distant, black hairs. Osmatcrium pale orange. Spi- 

 racles and legs of the color of the body, the basal joint of each with a large exterior 

 spot of black, the other joints blackish exteriorly. Prolegs of the color of the under 

 surface, the ventral pairs with a large black spot on the exterior of the basal joint: 

 the anal pair with a black spot between the joints behind and having the terminal joint 

 edged broadly with black, excepting behind. Length of body, 50 mm. ; breadth of head, 

 4 mm. ; breadth of body anteriorly, 8.5 mm. ; common stem of osmateria, 1.5 mm. long ; 

 the forks each 11 mm. long. 



Chrysalis (85 : 13, 18, 19). When it has first transformed it is a very light yellow- 

 ish brown tinged slightly with greenish, especially on the thorax; the head and all the 

 appendages are dark green with slight black streaks along some of the nervures of the 

 wings ; there is a narrow Isrown stigmatal baud. The whole, however, gradually turns 

 to a darker color, the green mostly disappears, excepting occasionally as a slight tint 

 and in a day or two it has assumed its permanent colors as follows : Light dirty 

 brown, the head and thorax and especially the wings of a hoary appearance, 

 the base of some of the nervures of the wings traced in black. Antennae and 

 tongue very dark green ; legs dark brown, the mesothoracic tubercle and the upper 

 surface as well as the upper portion of the sides of the ocellar iirominences black; a 

 broad, indistinct, dark brown, dorsal band on most of the abdominal segments, deepest 

 in tint on the fourth to seventh segments ; a dark brown stigmatal band broadest 

 and of deepest tint on the same segments ; and the posterior portion of the dor- 

 sal surface of each abdominal segment with a transverse internipted black line; 

 tubercles black. Length, 32 ram. ; breadth at ocellar tubercles, 4.25 mm. ; at thorax, 8 

 mm. ; at abdomen, 9 mm. ; height of thorax above general dorsal outline, 2.5 mm. ; 

 height of middle of the body, 9 ram. ; breadth of tip of creraaster, 2 mm. ; length of 

 booklets, .14 mm. ; breadth of their apical cup, .05 mm. ; of mass of booklets longitudi- 

 nally, .0 mm. ; of mass of booklets transversely, 1.2 mm.
