﻿56 NINTH ANNUAL KEPORT 



Larva — Newly hatched larva 1.9 m.m. long. Like unipuncta quite a looper, the pro- 

 legs on joints 6 and 7 very much reduced and useless. Head, cervical shield, and 

 shield, thoracic legs, rings on prologs, piliferous spots which are conspicuous and 

 normal in position, and bristles from them— black. General color sordid white, soon 

 becoming green. In the second siage the black parts become brown, and the body 

 above shows five pale lines on a ground of six dark ones, (in %mipuncta there are 7 pale 

 and 8 dark ones) generally indicated in the latter part of the first stage. In the third 

 stage the head is gamboge-yellow, and the dark lines are olivaceous and the contrast 

 with the five pale lines and the pale venter more decided. The looping habit is also 

 abandoned. In the fourth stage the head is honey-yellow with the mature markings 

 indicated in brown, and the five pale superior lines, especially the mediodorsai and the 

 next to it which is broadest, are relieved more strongly by a deepening of the borders 

 of the dark lines. In thefijth and sixth stages the characters of the mature l«irva are 

 approached by the narroAving of the medio-dorsal pale line, the deepening of the dorsal 

 and fading of the subdorsal dark space ; by the separation of the subdorsal pale line 

 into two, and by the deepening of the stigmatal dark line. 



Mature Larva — Average length rather more than an inch. Colors pale yellow and 

 brown. The brighter marked specimens have the dorsum brown with a narrow medio- 

 dorsal yellow line, obsolete posteriorly ; then a subdorsal sulphur-yellow line h as wide 

 and suffused in middle with carneous : then a still narrower brown line, ill defined, 

 beneath; then a yellow line of same width as preceding; then a somewhat broader 

 brown-black stigmatal line ; tben a substigmatal sulphur-yellow line as broad as 

 subdorsal and generally relieved below with pale brown — all the dark parts, except the 

 black stigmatal line, speckled with yellowish. Venter dull white. Head large, wider 

 ■than body, pale yellow — almost white, with brown tipped jaws, mottlings on the 

 cheeks, and two broad brown marks (with a tendency to fade in the middle) on top, 

 narrowing each side of V-shaped sutures. Stigmata white, with black annulus. (In uni- 

 puncta they are dark with a pale annulus). Piliferous spots though more conspicuous 

 than in imipu7icta in first stage, now less so. Varies considerably, some being quite 

 dark and others greatly suffused with rosaceous ; but the pale head, dark stigmatal line 

 and bright yellow lines are constant. 



Hundreds of specimens examined. Chryealis— normal form, and dark mahogany 

 brown. Distinguished at once from unipuncta by being more stronglj- punctate ; by 

 the anterior border of the three abdominal joints immediately below the wing-sheaths 

 being but slightly ridged, and deeply, profusely and irregularly punctate all round ; (in 

 miipuncta the?,e }oii\\.^ have, above only, a clearly defined ridge with a single row of 

 larger and regular punctations) by the stigmata being raised on a rounded prominence ; 

 and by the anal joint being much broader and more corrugate at base. 



Lnago — Average expanse 1.50 inch. Front wings either pale straw, or ochre- 

 yellow with a pale or white line along the median vein, broadening to the disc, and 

 sometimes extending more or less alongveins 3 and 4 ; tapering to base and blending 

 more or less with another pale line which extends a short distance beneath it and 

 fades away posteriorly, each sharply relieved below by a brown-black streak, shaded 

 with brown as follows : a broad pale costal border having a cinereous shade, with the 

 veins, especially towards apex, relieved and pale ; a terminal shade with similar cinere- 

 ous hue, and tapering to apex; a broad shade beneath median white line, with fre- 

 quently a dark, elliptic streak at its lower border toward base; and generally (not 

 always) connecting more or less distinctly with the terminal shade ; and lastly, a cunei- 

 form shade connecting with the terminal from vein 4 to apex, from which it curves 

 abruptly and tapers along the upper border of the median white line, which it helps 

 to relieve. A small discal dot. Tlie tapering shade is generally very clearly relieved 

 by dark streaks at its borders. Fringes white, usually with a dark medial line, and 

 always with a pale inner line relieved by a dark terminal line. Beneath white, with a 

 faint dusky tint opposite the cuneiform shade. Hind tvings, satiny-white, with fre- 

 quently a faint dusky shade posteriorly in the d". Head ochraceous-brown with paler
