 determined, as well as its extreme northern limits.

growth takes plaoe; the color becomes green with a yellow subdorsal line much as in the mature larva. The boilj- 

 is transversely creased. Duration of this stage about lour days. 



yornuil Sttiije II. — Not exhibited in any specimen seen by me, and prob.ably does not occur. 



Xormal Stage III (second stage). — Head large, slightly bilobed. narrowing a little to vertex and Ihittencd iu 

 front, pale green, hardly shiny, moutli white, ocelli and tips of jaws black; width, 1.4 to 1.55 mm. Body slender 

 smooth, no ))erceptible hairs; legs normal, green, somewhat shiny; a broad yellowish green subdorsal line; spiracle* 

 black. 



Xornutl Staijc I r {third stage). — ^Head as before; width, 2 to 2.35 nun. Body slender, nuiform green: a very 

 distinct, rather broad, pale yellow, subdorsal band from joint 2 to the anal plate ; spiracles black, faintly surrounded 

 by yellowish. Scattered, very small, and short seta-. 



yormal Star/v I V {(ourth st.age iu same larvte). — Head large, liatteued iu front, very slightly bilobed, smooth, 

 not shiny, pale green; ocelli black, labrum wliite, jaws black at tips, otherwise green; width, 2.7 to 2.8 mm. Body 

 transversely creased, leaf-green, with yellow piliferous dots bearing very small seta-. A slightly darker dorsal lino 

 and broad yellow subdorsal lino from joint 2 to the end of the anal j)late. .Spiracles black, with small white 

 centers. 



formal Stage F (fourth or lifth stage;. — He.ad shaped as before, pale green, not shiny; ocelli black on a white 

 ground, labrum white at tip, jaws green tipped with black, antenn;o yellowish; width, 3.2 to 3.7 mm. Body 

 yellow-ish green with many yellow irregular elliptical granulations and a distinct broad yellow subdorsal line,, 

 continuous from joint 2 to joint 13 and bordering the anal plate, which is rounded. Joint 2 is narrowly edged with 

 yellow in front. Spiracles dark brown, paler centrally. Feet green, without any yellow spots. 



Xormal Stage VI (fifth or sixth stage). — Hea<l full, rounded, slightly shiny, and absolutely shagrcened; jiartly 

 retracted under joint 2; uniform leaf-green, ocelli black on a white ground, mouth-parts whitish, jaws straw- 

 yellow, tipped with black; clypeus small, triangular; width, 4.6 to 4.8 mm. Body cylindrical, full, and roinided, 

 tapering slightly to the last segment, which is smaller than the rest, leaf-green or whitish green, densely covered 

 with white, irregular, liatteued elliptical granulations, which on the venter become transverse streaks. In siiecimens 

 in which the ground color is suffused with whitish, joint 2, joint 13 posteriorly, and the anal feet remain leaf-green. 

 A broad, distinct, white subdorsal line, faint on the anterior part of joint 2. The anterior edge of joint 2 and the 

 border of the anal plate are bright yellow. Feet green, the abdominal ones covered with white granulations, and 

 a wnite line before claspers. Spiracles orange-red, faintly bordered with white. The edges of the white subdors.il 

 band are not even, but more or less incised, on the anterior segments being narrowly broken into contiguous elliptical 

 areas, or in some specimens broken througliout the whole length. 



Cocoon. — The larvae enter the ground to pupate and form a rough cocoon of a t'uw strong silken threads. 



/'«j)«.— Cylindrical, tajjcriug, rather thick posteriorly to the thorax, the ends rouniled, most so anteriorly; 

 movable sutures of abdomen deep; cremaster long, rather thick, tapering, and ending in two short divergent points. 

 Body shiny, densely punctured; cases creased and also shiny. Color black, with a shade of brown on the abdomen. 

 Length, 22 mm. ; width, 7 mm. 



Food plant. — Black oak {Quercua Icelloggii Newberry). 



Nadaia orcgonennh is not well distinguished from X. gihhoaa Sm. & Abb., especially iu the larval state. It seems 

 to be related to gibbona much as I'apiVio riiliiliis is related to P. tuniiis among the bntterllies. Its habitat is very 

 probably coextensive with that of its food plant, which is said to be "on the coast ranges and on the wistern slope 

 of the Sierra Nevada throughout California and as far north as the middle of Oregon; on mountain sides and 

 summits only or in the elevated valleys, not on the i)laius or near the sea.'' Mr. Edwards recorded it from Siskiyou 

 and Butte counties, and I found it iu Mariposa County and at Portland, Oreg., but I am not aware that any record 

 of its capture iu the coast ranges has yet been made.
