40. Papilio {Menamopsis) perses, n. sp., Plate IV, Fig. 7, 6 .

Description: Male. Upperside, both wings fuscous. Forewing 

 with the basal two-thirds very dark fuscous, the outer third lighter. 

 Hindiving with a submarginal series of sullied- white streaks placed in 

 pairs between the veins, reaching neither the outer margin nor the dis- 

 coidal cell, most prominent at the anal angle, becoming obsolete towards 

 the apex of the wing ; a small round chrome-yellow spot outwardly 

 surrounded by a black line at the extreme anal angle. Underside, 

 both wings uniformly pale fuscous. Foreiving immaculate. Hindiving 

 with the anal spot as on the upperside ; the submarginal series of 

 white streaks longer, reaching almost to the outer margin, wider and 

 clearer white. Head and thora:c in front black, spotted with white, rest 

 of thorax and abdomen black, the latter beai^ing three series of white

Mr, W. F. Kirby has kindly compared the drawing here reproduced 

 with the specimen of P. hcivitsonii, "Westwood, in the British Museum, 

 which is probably the type of that species, and was figured by Mr. 

 Hcwitson in his " Exotic Butterflies," vol. ii, Papilio pi. iv, fig. 9, 

 (1859) as the female of P. slateri, Hcwitson. Mr. Kirby informs me 

 that the species here described in quite distinct from the Bornean 

 P. heivitsonii. The latter I have not seen, but from Hewitson's figure 

 of it, which he says is taken fi"om a female (Wallace, however, says the 

 specimen is a male,* as also does Westwood,t again Mr. G. C. Dudgeon 

 has examined it and tells me that it is, with two other specimens in the 

 British Museum, undoubtedly a male), it differs in having the outer 

 third of the forewing lighter coloui'ed than the rest of the wing instead 

 of concolorous throughout ; the hindwing with a prominent submar- 

 "■inal series of white streaks, instead of, as in P. heivitsoniif " two rows
