270 PERIZOMA. By L. B. Prottt. 



band atteniiated behind and somewhat interni])ted, the wings ])erhaps relatively more elongate. Formosa, 

 without indication of exact locality. 



tripliifiialii. P. triplagiata Warr. (= biplagiata Wüeman. eir. transcr.) (27 g). Forewing ahno^t immarked excepting 



the three dark patches from wliich it derives its name. Warken indicates that it may conceivably be a very 

 dififerent form of fenxfascia. but. aj^art from the other differences, it has an oehreous snffusion whieh Is wanting 

 in that species. Khasis (loc. typ.) and Sinila. 



irdriifaschi- P. fractlfasciaria Leech (Vol. 4. pl. 7 i). Whiter than coslivotaria. the midcostal dark pateh broader. a 



na. 



sniall mark opposite to it on the hindniargin (as in costata ab. partiriilata). Ta-tsien-hi. 1 ,3. Also 1 from Yunnan. 



hrerifasriata. P. brcvifasciata Warf. (Suppl.-Vol. 4, pl. l()b). Position somewhat doubtfiil. Antenna of the (J shortly 



ciliate, Ist radial uf the forewing not stalked, hindwing not qiiite regularly rounded. The type of maculation 

 is somewhat as in fractifasciaria but much more copious, a band developed l)etween the basal and the median, 

 a line intersecting each white band, dark outer shades stronger. Thundiani (type) and Darjiling. 



ccrni. P. cerva Hmps. (27 g). Much smaller than triplagiata, the glossy white forewing much suflused with 



cinnamon-buff. the midcostal mark greatly reduced, the subterminal costal somewhat extended, very near the 

 apex. >Sikkim, 700U feet (type) and Upper Burma. Palpus rather long. 



laecniif/cra. P. lacemigcra Biitl. (Suppl.-Vol. 4. pl. 14 k). This and the following have also elongate paljji and are 



probably related to cerva but are less brightly eoloured and more normally marked. the last costal spot not 

 so near the apex. lacemigcra is generally smaller than Jiockingii and has the termen of the forewing somewhat 

 more sinuous. Further differentiatious are given under hockingii. Both were described from Dharmsala and 

 extend tiu'ough Sikkim to N. Burma. 



horkinj'ii. P. hockingü Butt. (Vol. 4, pl. 7 k). Less glossy. Basal patch of forewing generally more oblique, central 



band better developed. less narrow". generally formed of a jjair of dark lines connected by a costal blotch ; fringe 

 scarcely so sharply marked. Specimens from the Nagas, so far as they are known to me. are larger. 



rcciijasrkda. P. rectifasciata Hmps. Lines and bands more equally expressed throughout the forewing than in the 



two preceding. approximately parallel and without any very strong projections; tone of colour somewhat as 

 in decorata. Hindwing somewhat less weakly marked than in most Perizoma. Sikkim, 7000 feet, apjjarently 

 very rare. 



dccorala. P. dccorata Moore (27 g). A neat little species. with sinuous median band (weakly indicated also on 



the whiter hindwing) and fairly conspicuous anterior half-band ]n-oximal to the subterminal, the subterminal 

 (luadrinotaid. more or less macular and with a large sj)ot or longitudinal streak in the middle. Sikkim. — quadrinotata Warr. 

 from Assam and Upper Burma (the type from the Khasis) is possibly a sejjarable race as the majority of the 

 specimens — especially from the Khasis — are more strongly marked; but there is considerable Variation 

 and Hampson was perhaps riglit in treating the two forms as synonymous. 



simuhiifi. P. si'mulata Wileman. Similar to decorata. indecd Wileman considers that some of the Sikkim specimens 



determined as decorata in the British Museum agree with his species. His unique type, however, a 1^ from 

 Arizan, Formosa (7300 feet), is much less brightly eoloured — whitish with the markings grey-brown, the sub- 

 terrainal spots not quite characteristically developed, It should be, I think, at least a subspecies. 



pueril i.'<. P. puerilis Prouf (Sup})l.-Vol. 4, pl, 16 a). Antennal ciliation of the o minute. Paler than decorata. fore- 



wing with apex more acute, termen more sinuous, median band narrow throughout, scarcely sinuous, sub- 

 terminal spots formed much as in decorata. their dark proximal shade developed chiefly in cellule 0, i. e. just 

 in front of the longitudinal white streak. Htawgaw, Kachin Hills, the type ^ ; besides, T know only a o labelled 

 "W. China". Superficially recalls the S. American genus Psaliodes. 



ocJinxiiincld. P. ochreotincta Wilutian (27 g). Wileman considers this also allied to /■". ''decorata"; perhaps this is 



so, but the type (J — iniibrtunateiy rubbed — looks to me to have more affinity with fasciata or others of the 

 taeniafa- group; it is hoped that our figure will give a correct impression of it. Basal and median bands well 

 defined. blackish, the latter bilobed distally, costal siUrterminal patch bearing 3 white dots, Rantaizan (type) 

 and Arizan, Formosa. 



pnrrana. P. parvaria Leech (= ablegata ^Igr.) (Vol. 4, pl. 7 k). Recognizable by its rather characteristically 



shaped median band, which has its distal lioundary and the lines which are ]jarallel therewith not dentate, but 



merely once sharply beut; distal area partly white opposite the angle. The Originals were "})robably from 



ntbidiv'imi. Yokohama", later material from Yamato, the Ussuri and W. China. Palpus rather short. - albidivisa Warr. 



(27 g), described from the Naga Hills and known in similar forms from the Khasis and X. ^\'. India. is perhaps
