190 TRIGONOPHORA; CHUTAPHA. By W. Warren. 



line filled in with violet grey, hmulate dentate; submarginal line green, inangled on each fold; hindwing 

 with basal half dull whitish, outer half fuscous black bej-ond an abbreviated outer line, both becoming 

 obsolete towards anal angle. An Indian species, occurring also at Yatong, Tibet. 



32. Genus: Trigonophora Hbn. 



Tongue present; frons smooth, with a thick tuft of hairs; palpi upturned, the second segment long 

 and thickly haired, the third short; antennae of $ with quite short sessile fascicles of cilia; thorax hairy; 

 tegulae produced to a central ridge; prothorax with single, metathorax with double crest; basal segments 

 of dorsum crested; the abdomen well-clothed with hair and with lateral tufts; forewing with termen more 

 or less deeply crenulate, and more or less strongly excised below middle. At rest the imago holds its 

 wings deeply folded against its body, the typical species thereby resembling a dry faded leaf. — Larva on 

 all low plants; double brooded except in the extreme North; pupation subterranean. Type Trigonophora 

 meticulosa L. 



meliculosa. T. meticulosa L. (= pallida Tutt) (44 a). Forewing whitish ochreous, the base and costal area to 



2 /a pinkish; a triangular space on inner margin before the inner line, the terminal area beyond submarginal 

 line, and a costal shade beyond outer line olive greenish; central area dark green, pinkish towards costa, 

 triangular in shape, the blunt apex resting on inner margin; the 3 stigmata more or less rosy green, the 

 two upper with pale lateral edges; outer line double and angled outwards on vein 5; submarginal line 

 preceded by a blackish green lunule between veins 6 and 7; fringe rufous green, blackish along the ex- 

 cison below vein 4; hindwihg pale ochreous, with the discal spot, veins, and often the whole inner half 

 tinged with greenish fuscous; dark outer and double submarginal lines, the latter often forming a grey 

 suffusa. band below vein 4; — in ab. suffusa ab. nov. (= var. A. Guen.) (44 a) the whole forewing is tinged with 

 reddish, partially obscuring the usual olive green tints; this form seems rare, but is probably not a local 

 one; Tutt mentions 3 specimens from Deal and I have seen two European examples, without exact locality; 

 also the examples from Terceira, the Azores, belong to this form, but there appears no ground whatever 

 roseo- for supposing that this red-suffused form is the typical form of Linne and Haworth; — ab. roseo- 

 brunnea. bmnnea ab. nov. (44 a), from the Azores, S. Jorge, occurring along with ab. suffusa, has the central triangle 

 rich redbrown tinged with fulvous, the whole wing reddish tinged, and the green shades all strongly mixed 

 with reddish, the metathorax and dorsal tufts also being deep fulvous instead of green. — Of general 

 distribution throughout Europe; found also in the Azores, in Algeria, and in Asia Minor, Armenia, and 

 Syria. — Larva dull green or pinkish-brown, thickly dotted with pale; dorsal line whitish, interrupted; 

 lateral lines narrowly whitish; segments 4 — 11 with oblique darker lateral stripes; polyphagous on low 

 plants. 



fuscomwrg^ j f uscomar gj n ata Leech (44 b). Forewing ochreous suffused with reddish brown, darker along the 



costa; a dark redbrown triangular patch along inner margin from base to outer line reaching to lower 

 angle of cell; terminal area dark purplish brown below vein 6, containing a blacker shade before sub- 

 marginal line; the apex above vein 6 pale ochreous; upper stigmata large, with pinkish grey annuli defined 

 by brown; outer line angled outwards on vein 5; hindwing brownish ochreous; a dark cellspot, outer line, 

 and subterminal and terminal band. Described by Leech from a single $ from Pu-tsu-fong, W. China. 



33. Genus: Chntapha Moore. 



Differs from Trigonophora in having the termen of forewing dentate but not excised below middle; 

 and in the tegulae not being produced in front to form a central ridge; the structure of the antennae is 

 variable. — Larva, as far as known, agreeing with Trigonophora. Type Chutapha costalis Moore. 



Sect. I. Antennae of $ bipectinate, the branches short, the apical third ciliated. 



inlerrupta. C. interrupta Warr. (44b). Forewing rufous ochreous; a brownish black wedge-shaped mark near 



base of inner margin; the cell and space below between the lines as far as submedian fold deep redbrown; 

 below this on vein 1 an oval redbrown ring; upper stigmata large, reddish ochreous, the orbicular rounded 

 below cell and confluent along median vein with the reniform which contains a redbrown lunule; outer 

 line double; the ochreous subterminal line lunulate-dentate, preceded by a dark shade; hindwing yellowish 

 ochreous, tinged with rufous fuscous, especially along termen; a dark cell mark, outer line, and submarginal 

 shade pit-ceding the pale submarginal line. 8. Jorge, the Azores. 



irollastoni. C. wollastoni B.-Baker (= periculosa Stgr. nee Guen.). Forewing bright rufous, dusted with black, 



especially in costal region; the outer area paler; inner line double, oblique and sinuous, filled in with pale, 

 but obscure, preceded by a faint waved line, which is less oblique; outer line also double, indistinct
