The British Museum has recently been presented, by Captain 

 Stackhouse Pinwill, with a fine collection of Lepidoptera from 

 Malacca and Penang, a complete list of which I hope shortly to 

 have the pleasure of laying before the Society for publication ; in 

 the meanwhile I am anxious to secure to the National Collection 

 the types of two of the finest novelties, and therefore hasten to 

 describe and name them. 



Thaumantis pseuualiris, n. sp. 



cJ differs from T. aliris S (Borneo) in having the band of primaries 

 half the width, not notched, yellower, and terminating upon the outer 

 instead of the inner margin ; the basal area of all the wings and 

 the body distinctly ferruginous ; below, the area beyond the band of 

 primaries is uniformly ferruginous, like the outer border, not striated ; 

 outer border paler externally, shortened by the obliquity of the trans- 

 verse band ; basal spots ferruginous instead of reddish brown and 

 black ; the irregular band of secondaries paler and much more con- 

 stricted in the centre; the external and discal areas altogether paler 

 and more uniform in tint, the ocelli very much smaller and paler ; 

 the spots between the ocelli and the yellow submarginal spots obso- 

 lete : expanse of wings 4 inches 7 lines. 

 S Malacca [Pinwill). 



Professor Westwood seems to have noted this species as the 

 male of his T. aliris (Trans. Eut. Soc. n. s. vol. iii. p. 17G, 1850- 

 1858); but as he figures the female of the Bornean species from 

 an example in his own possession, the latter must be considered 

 his type. 



Amesia pexifascia, n. sp. 



5 . Primaries rich purplish chocolate ; external two fifths covered by a 

 broad, externally deeply dentate-digitate, snow-white band, inter- 

 rupted by the black nervures, the portion filling the. end of the dis- 

 coidal cell divided longitudinally so as to form two large si)ots; 

 secondaries almost exactly as m A. euploeoides, hut the anal angle 

 deep greenish grey ; body deep purplish chocolate, the last three seg- 

 ments of the abdomen green ; palpi, tegulse, and thorax dotted with 

 lilacine ; primaries below as above, excepting that there are a basal 

 white spot, two costal, two subcostal, two discoidal, and two interno •
