12 METALLOLOPHIA; TERPNA. By L. B. Prottt. 



3. Genus: Metallolophia Warr. 



Palpus moderate, third joint in ? moderate or longish. Antenna rather long, lamellate or nearly 

 simple. Abdomen crested, in the nametype (vitticosta) with the crests metalhcally glossy. ForeAving in ^ 

 more or less elongate, the distal margin being very oblique, first subcostal vein free; hindwing with neuration 

 nearly as in preceding genus. Excepting arenaria, only a few Indo-Malayan species are known. The genus 

 is closely related to Terpna. 



armaria. M. arenaria Leech (1 e). Whitish, with shght ohve-brown clouding and with coarse purple-brown 



irroration in places. The Hnes and a very large oval discal mark on forewing oMve-brown, the discal mark 

 surrounted, and the postmedian line in part overlaid with dark purple; postmedian hne irregular, much 

 excurved anteriorly, but without sharp angles as in opalina Warr. Hindwing weakly marked (probably 

 somewhat faded). Under surface of both wings with some blotches near base, large oval discal mark and 

 thick, curved postdiscal line or shade. Central China: Kiiikiang. Only Leech's type ($) yet known. 



4. Genus : Terpna H.-Sch. 



Not very sharply differentiable from the preceding genus, which could almost be treated as a sub- 

 genus of it. Frons strongly protuberant, antemia in (J nearly always, and in $ sometimes bipectinate, tho- 

 rax densely hairy beneath, metathorax sometimes crested, abdominal crests never metalhc. Forewing broad, 

 with distal margin not extremely obhque. 



A genus of ample-winged, robustly built moths of rather wide distribution in the south-eastern 

 Palearctic and the Indo-AustraUan Regions! They show a good deal of diversity in structure, and I have 

 elsewhere divided the genus into 8 subgenera according to the antennal structure, shape of wings, length of 

 cells and other characters. For the half-dozen Palearctic species this subdivision may be set aside. 



decorafa. T. decorata Warr. (= dorsocristata Pouj.) (3c). Antenna simple. Distal margins of wings not crenu- 



late. White, finely dusted with ohve browii, both wings \vith a curved or angulated dark cell-mark and a 

 much interrupted postmedian hne, the latter followed distally by some reddish blotches, that nearest apex 

 of forewing large, fuscous-mixed, tridentate. Fore%ving also with large antemedian spot on costa. Underside 

 with the markings ampler, more fuscous, the ceU-spots very large. Bhotan, Mou-pin and Chang- Yang. 



a'mpHficata. T. amplificata Walk. (le). Antenna in (J pectinate. Abdominal crests not strong. Wings with cells 



very short. White, laeavily blotched with brownish grey, and more or less strongly clouded with yellow dis- 

 tally, especially at anal angle of both wdngs, fore^vang with a small yellow patch at base. Under surface 

 similarly marked, but without the yellow distal shading, the proximal on the other hand somewhat exten- 

 ded and common to both wings. Distributed across China at about 30 " N. Lat. Variable in the strength 

 and extent of the yellow shading. 



leucomela- T. leucomelanaria Poiij. (le). Nearly related to amplificata, but more darkly and heavily marked 



nana. -^{^^ grey, which here becomes nearly or quite black. The distribution of the dark colour is also different, 

 especially on the forewing, where it almost covers the distal third of the wing, widens still further in apical 

 area, and extends more narrowly and somewhat interrupted along costa. Only known from Mou-pin. 



superans. T. superans Btlr. (Ig). Antenna rather short, in ^ with moderate, in $ with short pectinations. 



Build very robust, especially in $. Cells not very short. Very pale brownish, the entire wing, or at least 

 a band distally to the postmedian line, dusted with grey or olive-grey. Postmedian line dentate, weak ex- 

 cept from costa to first radial and on the other veins; forewing also with a weak antemedian hne. Under- 

 side with cell-marks and postmedian clouding very large and heavy, two dark streaks on grey clouding at 

 base. $ usually much larger than ^. Japan. 



leopardi- T. leopardinata ilfoore (1 g). Antenna moderately long, in cj shortly, in $ not bipectinate. Metathorax 



naia. moderately, abdomen strongly crested. Forewing yellowish green, thickly sprinkled with fuscous, suffused 



with reddish in central area and distally to the postmedian hne. Lines dark, diffuse, overlaid with shining
