It thus appears to extend throughout the Appalachian, Austroriparian, and Campestrian 
subprovinces; whether it occurs in the Mexican (Sonoran) subproviuce remains yet to be 
determined, as well as its extreme northern limits.

growth takes place; the color becomes green with a yellow snbdorsal line much as in the mature larva. The body 
is transversely creased. Duration of this stage about four days. 
Normal Stage II . — Not exhibited in any specimen seen by me, and probably does not occur. 
Normal Stage III (second stage). — Head large, sJiglitly bilobed, narrowing a little to vertex and battened in 
front, pale green, hardly shiny, mouth white, ocelli and tips of Jaws black; width, 1.4 to 1.55 mm. Body slender 
smooth, no iiercoptiblo hairs; legs normal, green, somewhat shiny; a broad yellowish green subdorsal line; spiracles, 
black. 
Normal Stage IV (third stage). — Hoad as before; width, 2 to 2.35 mm. Body slender, uniform, green; a very 
distinct, nitber broad, pale yellow, subdorsal band from joint 2 to the anal plate; spiracles black, faintly surrounded 
by yellowish. Scattered, very small, and short sotte. 
Normal dS'/a/ye IT (fourth stage in same larvio). — Head largo, Ihittened in front, very slightly bilobed, smooth, 
not shiny, pale green ; ocelli black, lahrum white, jaws black at tips, otherwise green ; width, 2.7 to 2.8 mm. Body 
transversely creased, leaf-green, with yellow piliferous dots hearing very small setie. A slightly darker dorsal line 
and broad yellow subdorsal line from joint 2 to the end of the anal plate. Spiracles black, with small white 
centers. 
Normal Stage V (fourth or tifth stage). — Head shaped as before, pale green, not shiny; ocelli black on a white 
ground, labrum white at tip, jaws green tipped with black, auteuum yellowish; width, 3.2 to 3.7 mm. Body 
yellowish 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 jdute, which is rounded. Joint 2 is narrowly edged with 
yellow in front. Spiracles dark brown, paler centrally. Feet green, without any yellow s]»ots. 
Normal Stage VI (tifth or sixth stage). — Head full, rounded, slightly shiny, and absolutely shagreened; partly 
retracted uuder joint 2; uniform leaf-green, ocelli black on a white ground, mouth-parts whitish, jaws straw- 
yellow, tip]»ed with black; clypens small, Iriaugiilar; width, 4.C to 4,8 mm. Body cylindrical, full, and rounded, 
tapering slightly to the hist segment, which is smaller than the rest, leaf-green or whitish green, densely covered 
with white, irregular, tlattened elliptical graiuilatious, which on the venter become transverse streaks. In specimens 
in which the ground color is suffused with whitish, joint 2, joint 13 posteriorly, and the anal feet remain leal- green. 
A broad, distinct, wliite subdorsal lino, faint ou the anterior part of joint 2. The anterior edge of joint 2 and the 
border of the anal jilato are bright yellow. Feet greeu, the abdominal ones covered with white granulations, and 
a white line before claspers. Spiracles oraiige-rcd, faintly bordered with white. The edges of the white snbdorsal 
band arc nob even, but more or less incised, on the anterior segiueiits being narrowly broken into contiguous elliptical 
areas, or in some specimens broken throughout the whole length. 
Cocoon . — The larvaj enter the ground to pupate and form a rough cocoon of a few strong silken threads. 
Pupa. — Cylindrical, tapering, rather thick posteriorly to the thorax, the ends rounded, 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 {QuercMS Icelloggii Newberry). 
Nadata oregonensia is not well clistiugiiished from N. gihhoea Sm. & Abb., especially in the larval state. It seems, 
to be related to gibhona much as Papilio rutuliis is related to P. tiirnns among the biitterliies. Its habitat is very 
probably coextensive with that of its food plant, which is said to bo the coast ranges and ou the western 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)lairis or near the sea.'^ Mr. Edwards recorded it from Siskiyou 
and Butte counties, and I found it in Mariposa County and at Portland, Oreg., but I am not aware that any record 
of its capture in the coast ranges has yet been made.
