PAPILIONINAE : EUPIIOEADES TROILUS. 1319 



these variations in tone tliere are tlie same markings tliat are described for tlie previ- 

 ous stage, tlie piceovis and velvety patches, the loniiitudinally oval, turquoise spots, 

 the glistening warts, etc., and they do not dift'er in any marlced respect. Length, 25 

 mm. ; breadth of head, 2.G5 mm. ; of first thoracic segment, 3.5 mm. ; of tliird thoracic 

 segment, fi.o mm. ; of eighth thoracic segment, 4 mm. 



In specimens which are of the pale olivaceous type, the markings differ slightly, for 

 there is a pair of large, oval, yellowish brown spots on eitlier side of the dorsal line 

 of the tlrst abdominal segment, truncate posteriorly by the segmental line, and having 

 the turquoise spot of this segment near their middle. Accompanying this the ))lack 

 patch is very mucti more broadly bordered with this same yellowish brown above, 

 coming half way to its appearance in the next stage, and in very marked distinction 

 from the appearance of the other individuals of the same stage. 



Last stage (76 : 18). Head (79 : 73) pale green ; antennae pale, ocelli pale or darker 

 yellowish brown or slightly fuscous. Mouth parts pale, excepting a spot at the base 

 of the mandibles and the extreme edge of the same, which are reddish. Body above 

 darker rich green, of the color of the sassafras leaf on the thoracic segments, a little 

 paler on the abdominal segments, from being more or less flecked with obscure, paler 

 spots, scarcely visible to the unaided eye. A wavy, slightly irregular, black stig- 

 matal line extends from the apices of the osmaterial oriflce to the middle of the last 

 abdominal segment. Just above this is a pale, clear yellow band, which also borders 

 the osmaterial oriflce posteriorly, where it is brighter and is followed by a transverse, 

 piceous patch, traversed by a delicate dorsal line, the hinder border of the patch being 

 straight and the front border convex. On either side of the third thoracic segment is 

 a large, nearly circular, pale buflf, supralateral spot, extending nearly across the seg- 

 ment, bordered with a fine black line, and having within it, in the lower posterior 

 corner, a large reniform, velvety black patch, in the lower posterior corner of which 

 patch again is a piceous, ronnded wart ; anteriorly the spot has a transverse, bent, 

 narrow black streak, sometimes joined to the patch ; and above, a small, longitudinal, 

 ovoid, turquoise spot, narrowly edged with black ; on the flrst abdominal segment is a 

 pair of circular, buft' colored, laterodorsal spots, a little more than half as large as 

 those of the preceding segment, edged with black and having within them anteriorly a 

 small, longitudinal, ovoid, turquoise spot edged with black. There is a laterodorsal 

 series, of small, ovoid, turquoise spots, edged with black, on the second to eighth 

 abdominal segments, quite small on the second, third and eighth segments, and largest 

 on the flfth and sixth ; a similar lateral row on tlie second to seventh abdominal seg- 

 ments, and an infrastigmatal series of similar but nearly equal triangular spots on the 

 second to eighth abdominal segments. Beneath pale green, tinged with dull brownish 

 roseate, especially on the abdominal segments. Osmaterium lemon yellow. Spiracles 

 pale green, edged very narrowly with black. Legs and prolegs of the color of the 

 under surface. Length, 27.5 mm. ; breadth of head, 4 mm. ; of body, at third thoracic 

 segment, 8 mm. ; at third abdominal segment, 5.75 mm. ; at seventh abdominal seg- 

 ment, 4.25 mm. ; at eighth abdominal segment, 5 mm. 



Other specimens measured 38 mm. long and 10 mm. broad. After evisceration, the 

 caterpillar, besides shrinking greatly in size, turns of a yellow color, although occa- 

 sionally the change of color takes place previous to the evacuation of the contents of 

 the intestinal canal. 



Chrysalis (85:5-7; 87 ;G, 15). The whole dorsal surface either pale yellowish 

 green, becoming yellow toward the middle, and with a reddish brown dorsal line, 

 obsolete on the head and posterior half of the mesonotum ; or, griseons with mingled 

 yellowish and reddish brown dottings, paler next the middle , and with a dusky dorsal 

 line, interrupted as above. Whole ventral surface either delicate pale grass green, 

 the legs spotted a little with black and rusty brown ; or, grayish brown, darkest on the 

 appendages, marked with delicate, dull yellowish lines. The ocellar prominences (86 : 

 34, 35) are always brownish fuscous, and the dorsal carina bordered with reddish 

 brown or brownish fuscous, and itself crested with a paler color. There is a latero- 

 dorsal row of minute whitish spots, ringed with blackish brown, extending from the
