 median band developed. recalling extreme forms of confuncta: but as all the '^ known examplcs havc unequi-

P. conjuncta Warr. (27 g). Variable, but never with the median band fuUy darkened, yet always with conjimda. 

 its costal part blaekish; subterminal shades generally strong; fringe strongly spotted. Tiie long palpus and the 

 crested abdomen suggest doubt as to its belonging is Perizoma; diseoeellulars weakly biangulate. East Pegu 

 (loc. typ.), the Khasis andHtawgaw, Upper Burma. The few speeimens yet known from the Kachin Hills and 

 Teng-yueh-ting are exceptionally small and may represent a snbspecies.

 the hindwing. however, ligiiter and generally more sharjily marked; termen of hindwing more sinuous. Very 

 distinct in the sinuous white subterminal line of the forewing, which is placed very near the margin and separated 

 therefrom by consi^icuoiis dark spots; a hindmarginal spot between basal and median band is also noteworthy.

 if not a form of the same species. Nearly always larger, botli wings generally a little more irregulär in shape: 

 median band relatively broader, more sharjjly defined proximally, subbasal l)and complete, not accentuated

P. (?) contrastaria Sterneck is unknown to nie. Expanse "18 mm". Palpus moderately long. Antenna conirastaria. 

 of c5 simple, much tliickened. Diseoeellulars of hindwing biangulate, 2nd subcostal long-stalked. Forewing 

 with cell-spot large, black; proximal and distal areas blaekish, traversed re.spectively by a weak lighter sub- 

 basal and a punctiform subterminal; median area white, in the middle — especially anteriorly — darkened with 

 vein-streaks and dots, only its borders remaining clean white.. Hindwing white, darkened at anal angle; cell-dot 

 distinct; basal and terminal bands grey. Wassekou, W. China. 



P. rantaizanensis Wileman. Clofsely related to alhofasciata (27 h), perhaps a subspecies. The apical dash rantahane»- 

 of the forewing is perhaps less sharply white and (to judge from a few ])ooi- speeimens) the median band may •'"■'*■ 



be more mixed with grey than in most aUiofa.'^ciala. less narrowerl posteriorly and with less strong dark mark 

 on hindmargin. The white hindwing shows at least a trace of 2 lines outside the ceibdot. Formosa: Rantaizan. 



P. albofasciata Moore (Vol. 4. \)\. 7 h). Readily recognizable from our figure; the median band is always albofasciata. 

 more or less ill-detined (mixed with white), sometimes very feeble excejil at costa and hindmargin; postmedian 

 marked by dots or small dashes on the veins, rarely traceable on the hindwing. Darjiling (loc. typ.) and up 

 to 10 000 "feet at Tonglo. A similar, or still whiter-banded form occurs at Uharmsala. — f. mixtifascia Protit is mixtifascia. 

 smaller (19 — 22 mm), the white outer spot of the forewing somewhat, the median area eonsiderably. more irror- 

 ated with dark grey, the irroration in this latter area extending to the postmedian line. Kachin Hills and prob- 

 ably Kwanhsien, Szechuan.
