86 THE CANADIAN ENTOMOLOGIST. 



Mature Larva. — Length ^,1.2 inch, greatest breadth (in middle 

 segments) .16 inch ; ^ 1.4 in., gr. br. .17 inch ; the dorsum much arched 

 and sloping about equally either way from middle segments ; ending in 

 two small, short and slender tails ; each segment several times creased, the 

 front ridge so caused flattened and about twice as broad as any other, the 

 others equal and rounded ; covered with fine whitish tubercles, mostly 

 disposed in longitudinal rows, each bearing a short stiff hair ; color yel- 

 low-green ; on middle of dorsum a dark green band ; on the edge of 

 dorsal area a yellow line to tail, and on upper side of this a dark green 

 line ; another such on middle of side ; along base a narrow yellow stripe ; 

 tails pink-tipped ; under side, feet and legs pale green ; head obovoid, 

 well rounded on front and sides, the vertices high, each bearing a stout 

 tapering process or horn, tuberculated ; color yellow-green, the upper part 

 of horns red ; the sides of face bear many rather large, white, conical and 

 separated tubercles, disposed in oblique rows ; ocelli brown ; in one 

 position the largest is green with a brown rim, at other angles it is brown. 

 From 5 th moult to pupation 15 to 16 days. 



Chrysalis.— Length .6 in. ; greatest breadth, across base of wings 

 .22, across abdomen .22 inch; cylindrical, the abdomen conical, the wing 

 cases considerably raised along dorsal side ; the head case short bevelled 

 transversely to a sharp edge, roundly excavated on the sides, the top 

 rather broad, very little incurved, the corners sharp but not produced ; 

 mesonotum prominent, angular, the apex rounded, carinated, the sides 

 flat and sloping ; color delicate green, sometimes blue-green, the ventral 

 side of abdomen lighter or whitish ; the top of head case and edges of 

 wing cases next dorsum cream color ; surface smooth, glossy. Duration 

 of this stage 13 to 14 days. 



The chrysalis much resembles that of Satyrus Alope ; the head case is 

 broader, sharper-edged, the mesonotum more angular and more promin- 

 ent, and the abdomen more protuberant on the dorsal side ; the surface is 

 also smooth, with no granulations. 



The caterpillar also somewhat resembles that of Satyrus Alope, much 

 more than it resembles any of our species of Neonympha, except that the 

 head bears a pair of horns or processes, as do several of the Neonymphee, 

 whereas the head of Alope is round. The egg is quite unlike Satyrus, of 

 which I have seen several species, all having been rather cylindrical, with 

 vertical ribs. Whereas the egg of Portlandia is rounded and smooth, very 

 much as Neon. Canthus, but more ovoidal.
