P. darlisa, Moore, Proc. Zool. Soc. Lond. 1878, p. 829, £ $ . 



Both sexes of this distinct species were described by Mr. Moore from 

 specimens in my collection obtained in April at Meetan in Upper Tenasse- 

 rim at an elevation of 3,000 feet. 



Two specimens of the male out of many captured in March last by 

 Captain Bingham in the Thoungyeen forests have been presented to the 

 Museum by Captain Marshall. 



This species also differs from P. lisarda in its broader wings, a charac- 

 ter not mentioned by Moore in his description of the species. 



The scanty setose clothing of the base of the posterior wings is 

 fuscous. 



5. Penthema Binghami, n. sp., PI. IV, Fig. 1. 

 $ . Differs from P. darlisa in having fully the basal half (including 

 the same extent of the abdomial area in the posterior wings) of all the 

 wings devoid of markings, the submarginal and discal series of spots alone 

 remaining in both pairs ; these two series of spots are bluish-white in the 

 anterior wings and of a beautiful straw-yellow in the posterior wings ; 

 they are, in fact, of the same colour, size, and shape as in P. darlisa ; but 

 the inner of the latter two series is closer to the outer, which is placed at 

 the same distance from the external margin of the wings. The wings are 

 all also somewhat narrower than in P. darlisa, thus approaching those 

 of the typical species ; and the posterior pair are furnished on the basal 

 half, between the median and submedian veins and in the discoidal cell, 

 with a thick and conspicuous furry clothing of rich dark fuscous setae 

 exactly matching the dark ground-colour of the wings and the abdomen 

 of the insect in shade, which setose clothing is so scantily developed as to 

 be quite inconspicuous in both the previously described species. The 

 whole body, too, but especially the abdomen, is much darker-coloured than 

 in either of them. Shadowy traces of the lost spots are faintly discernible 

 on the anterior wings. 



Hab. The Thoungyeen forests, British Burmah, where a single 

 specimen was obtained in March last by Captain Bingham, after whom, 

 at Captain Marshall's suggestion, I have much pleasure in naming it.
