SATYRUS II., III. 



ing towards either extremity; ending in two sharp, conical, divergent tails; 

 each segment creased five or six times, the intervening ridges covered with fine 

 white papilla?, each of which sends forth a white hair, longer or shorter, if long, 

 appressed to the surface ; coh^r yellow-green, hnt there was much variation, some 

 examples being uniform on back and sides, in others the dorsum was more yel- 

 low ; so the yellow-green was either light or dull ; on middle of dorsum a dark 

 green stripe, obsolescent in the middle segments; along basal ridge a yellow 

 stripe ; on the side in some examples, a faint yellow line, in others there was no 

 line, but a mere discoloration; under side, legs and pro-legs deep green; spira- 

 cles oval, color red-buff ; head sub-globose, narrowing upwards, a little higher 

 than Inoad. the top slightly depressed ; covered with conical white papilkv in 

 vertical rows, each with a white hair; color vivid-green; the third ocellus much 

 the largest, emerald-green, the others reddish. (Fig. h. /r.) The larva suspends 

 to a button of white silk, and the dorsum is then convex, the anterior segments 

 beinu' turned at a, rio-jit an<ide, bendintr at 5. (Fio-. /.) 



Chrysalis. — Length, <?.•"((') to .(1 inch, breadth .2 to .22 inch; 9 length .8, 

 breadth .22 to .24 inch; cylindrical, the abdomen conical;" the wing cases 

 slightly raised at the margins ; head case short, roundly excavated at the sides, 

 the top narrow, sometimes nearly square or a little arched, sometimes de- 

 pressed ; mesonotum slightly prominent, roundly carinated, the sides nearly flat, 

 or a little convex ; whole surface of the male one shade, either of yellow-green 

 or deep green, covered with smooth sjiecks and patches of a lighter color, but 

 which scarcely affect the general green hue ; along the inner margins of wine 

 cases a cream-colored line ; another on keel of me.sonotinn, and one across top of 

 head ca.se. (Fig.y.) In the female there are three longitudinal yellowish cloudy 

 bands, one on middle of abdomen to mesonotum, the others sub-dor.sal, extending 

 from end to end ; the wing cases clouded with darker green in long rays. 

 (Figs. A', Tr.) Duration of this stage about fourteen days. 



The larva? of Olympus, in their later stages, were distinguishable from those 

 of A/ope or typical Nephde. Thus, 



After third moult : there was present a distinct yellow side stripe, narrower 

 than the basal, but as deep colored as that ; also, the medio-dorsal green stripe 

 had a narrow edge on either side of yellow. 



Mature Larva. — Length, i L3G inch ; greatest breadth, .14 inch; slender, 

 yellow-green, the dorsum brighter -than the sides ; the upper stripe either deep 

 \ellow or pale yellow, distinct always ; tlie dorsal band edged with deep or pale 

 yellow. (III., Fig. a.) 



Chrysalis. — Color bluish-green, finely mottled, streaked and specked with 

 whiti,sh ; the lines alont;- the wing cases, mesonotum, and head white. (III.. Fiu-.
