1838 BUTTERFLIES BEYOND NEW ENGLAND. 



ment, and these last were larger than any others ; six seems to be the full uumber ou a 

 segment, and they vary from that to one, present on some segments, and lacking on 

 others, with no apparent regularity; so also the number of lateral processes differs 

 much; one had these on all segments except the first thoracic, first, fifth and ninth ab- 

 dominal segments, as the stage progresses a yellow stain appears on the baud of each 

 segment, and at last is often orange tinted. Length, 8-9.5 mm. 



Fifth stacje. Head round, slightly depressed at top with many fine black jioints, each 

 with short black hair; color yellow green. Body cylindrical, of nearly even thickness 

 from the second thoracic to seventh abdominal segments, thickly covered with smal 

 black tubercles, each of which gives a short black hair; color yellow green, light or 

 dark; along base a yellow white band, with a dash of orange on each segment, and 

 sometimes the orange is nearly continuous ; over the band, on the second and third 

 thoracic segments, a large, vitreous, black, rounded process, from the top of which 

 comes a small hair, and around the base is a ring of black points ; some larvae have 

 additional processes of same character on the succeeding segments ; but there is much 

 variation; occasionally all are large as on the second thoracic segment, usually they 

 are much smaller; in one example they diminish regularly on the abdominal segments ; 

 on dorsum of one or many segments are small black processes on the second ridge, 

 varying from six to one, and often wanting ; the same ridge is covered by a black 

 band, sometimes present on every segment, sometimes only on the two or three ante- 

 rior ones, with broken lines on dor.sum or sides of the succeeding ones, frequently, 

 however, wanting ; in many examples the first ridge of every segment is bright yel- 

 low, and the complete series of black and yellow bands is often present; but others 

 have the yellow bands broken up ou middle and last segments, or lack them on these 

 segments ; others have a yellow line instead of band ; and often there is no trace of 

 yellow anywhere ; some larvae, therefore, are wholly green, some green with yellow 

 bands, some with black bands and no yellow, Init more have both black and yellow, 

 with variation as to extent of either; the black bands appear in the fifth stage, in ex- 

 amples which showed no trace of them in previous stage, and some larvae wholly 

 "reen to end of fourth stage, at the moult took ou aU the bands ; under side, legs and 

 prolegs pale green. Length, 15-19 mm. 



There was much change in the markings at the previous moult, but still more at this. 

 Some which had been wholly green at this moult discover cross bands of black and 

 yellow, one or both, and there was much variation in the extent of these bands. 



Chrysalis. Shape of enrydice, tompressed laterally, the thorax on ventral side 

 prominent, rising to a narrow ridge; the abdomen tapering, conical, the mesonotum 

 low, rounded, with a slight carina, followed by a shallow excavation, the head case 

 produced to a point, a little curved up, with a regular slope on both dorsal and ventral 

 sides, angular laterally ; color bluish green over whole dorsal side, below, the abdo- 

 men yellow green; the wing and head cases dusky green, on the under side a brown 

 crescent, on dorsum two rows of black dots from mesonotum to eighth abdominal seg- 

 ment, one to each segment, and a small black spot on either side abdomen ; the whole 

 surface except wings dotted or finely streaked with whitish. Length, 20 mm. ; breadth 

 at mesonotum and on abdomen, 4.6 mm. ; greatest depth, 6 mm. 



Another example gave same dimensious; the dorsum yellow gi'een, ventral side of 

 abdomen more yellow ; a browu patch on under side of head case. 



An abundant species of the southern and especially the southwestern 

 states, extending from the Atlantic to the Pacific, and reaching down into 

 Mexico and Guatemala, and found as well on the larger West India islands 

 — Cuba, Jamaica and St. Domingo — it has been reported as far nortli as 

 Kansas, Wisconsin, southern Ontario and Pennsylvania, but does not 

 usually extend so far north in the east as it does in the central portion of 

 the continent.
