PlEEIS OBERTHURI, Sp. n. 



$ . White. Primaries : costa bordered with black ; nervules edged on each 

 side with black, expanding towards the outer margin, which appears in con- 

 sequence to be deeply bordered. Secondaries black at outer angle and half- 

 way along the costa ; nervules bordered with black, and there are streaks of 

 the same colour in the interspaces, pointed towards outer margin and bifur- 

 cated at their inner end. Under smtface similar to above, but the streaks in 

 interspaces of secondaries are connected with the borders of nervules ; a deep 

 yellow patch at base of secondaries. 



? . The black borders of nervules of primaries are not quite so broad 

 as in the male, but otherwise there is no difference in the markings of the 

 sexes. Expanse, $ 80 mm., ? 92 mm. 



In one specimen the whole of the primaries is black with the 

 exception of the discoidal cell, a broad patch from the base 

 between the median nerve and inner margin, intersected by the 

 submedian and a curved series of five oblong spots beyond the 

 middle of the wing. 



A fine series taken in April and June, at Chang Yang. 



Allied to P. acrcea, Oberth., but differing therefrom in the 

 character of the marginal borders. 



Delias patrua, sp. n. 



$ . Black. Costa, inner angle, discoidal cell, and nervular interspaces 

 streaked with grey, the streaks in latter are attenuated towards outer margins, 

 before which they unite with a whitish-centred grey spot, those nearest apex 

 are linear, and the streaks preceding are not always well defined. Secondaries, 

 inner area of the wings within submedian nervure, and a portion of interspace 

 above canary-yellow, each interspace above has a grey streak, those between 

 the median nervules are centred with white, and the upper one is only 

 separated from a broad discal streak by the disco-cellular nervule ; a series 

 of grey spots before the outer margin, those nearest anal angle with yellow 

 linear centres. Under surface black ; primaries with the streaks and spots 

 as above but white, the costa is only sprinkled with grey scales, there are 

 two short yellow dashes between costa and submedian nervure towards apex, 

 and the spots nearest apex are more or less yellow : secondaries have canary- 

 yellow markings, a broad patch at the base intersected by the praecostal, a 

 broad streak, whitish towards base, in the discoidal cell ; inner area as above ; 

 a central and submarginal series of spots, but the former are only suffused 

 with yellow to a greater or lesser extent. Fringes grey and black. 



2 . Fuliginous-black, the costa less grey, the streaks are shorter and 

 are not connected with the spots towards outer margin; the inner area 

 above is whitish towards abdominal fold. Expanse, $ 88 mm., $ 92 mm, 



A fine series, Chang Yang, June. 



Closely allied to D. belladonna, but at once separated by the 

 absence of yellow patch at base of secondaries. 



Pterogospidea diversa, sp. n. 

 Brownish black. Primaries have three subhyaline spots on the disc, and 

 five very small ones towards apex, the central spots form a triangle, a lunar 

 or linear one at end of discoidal cell, one rather larger and more quadrate 

 beyond, and a still larger one below, of the outer five the second is punctiform 

 and placed inwards, the fourth rather outwards, and the remaining two are 

 directly under the first ; a white spot in the submedian interspace under the 

 larger subhyaline one. Secondares have a broad white central band
