on, also. It will be seen that the key is not very satisfactory as regards 

 the grouping into genera ; so that it is probable that it is thoroughly 

 artificial though something might be got out of repeated efforts at classifi- 

 cation of the kind. One of the objections to any such co-ordination of facts 

 at the present time is the fragmentary knowledge available as there are 

 hundreds and hundreds of species of this family the larvse of which are 

 quite unknown. However, as said before, the key has to be taken for what 

 it is worth and may be useful later on as a sort of basis to work upon when 

 there is more material forthcoming. 



The species with an asterisk placed against them are such as have not 

 been included in the key to the imagines or perfect insects. These were 

 originally left out because it was thought that they were confined as to 

 locality to the Kanara District of the Bombay Presidency, their occurrence 

 not having been noticed elsewhere. Some few SatyrirKs, Nymphalin^ and 

 Papilionince have been omitted also for the same reason in former parts of 

 these papers. All these will be brought out as an appendix at the end of 

 the Hesperiidce, the last group to be dealt with. It would have been 

 simpler to have included them all at the beginning but that cannot now 

 be helped. 



Genus — Neopithecops. 



This genus extends from India and Ceylon to Burma, the Andaman 

 Islands and the Malay Peninsula. There is only one species known from 

 India, Ceylon and Burma : the one described here. It has wet-and-dry 

 season broods. 



127. Neopithecops z?L\mor?i.— Wet-season brood. — Male and female. Upper- 

 side : dark purplish brown ; in the female slightly paler on the disc of the 

 fore wing. In most specimens, but not in all, the male also has the disc of 

 the fore wing similarly paler. Underside: white. Fore wing : apex dusky 

 brown, apices of veins 10, 11, 12 with a minute, black dot; no discal 

 markings, but the discocellulars picked out with a short, very slender, 

 obscure, brown line ; a postdiscal, irregular transverse series of slender, 

 brown lunules, followed by a transverse, very slender, sinuous, brown line, 

 the white ground-colour in the interspaces beyond centred by a subterminal 

 series of transverse, black spots. Hind wing : discocellulars with a short, 

 brown line similar to that on the fore wing, followed by a subdorsal, round, 

 black spot and a subcostal, much larger, similar spot ; between these two 

 spots is a curved, very irregular line of detached, pale ashy-brown lunules ; 

 tlae subterminal markings very similar to those on the fore wing. Cilia of 

 fore wing dusky brown, of hind wing, white. Antennse, head, thorax and 

 abdomen dark brown; antennse, on the inner side, speckled with white ; 

 beneath : the palpi, thorax and abdomen white. 



Dry-season brood. — Male and female. Differs from specimen of the wet- 

 season brood as follows : — Upp>erside: ground-colour not so dark generally. 

 Fore wing : a large oval, snow-white spot placed obliquely on the disc. 

 Hind wing : apex and disc irregularly white ; on the posterior half the 

 ground-colour a shade darker than on the anterior half. Underside : 

 ground-colour and markings similar to those of specimens of the wet-season 

 brood, but the markings very much paler and fainter ; in specimens taken 

 in the middle of the dry season in exceptionally dry localities these mark- 

 ings are altogether absent. Antennse, head, thorax and abdomen on the 

 upperside paler than in the wet-season brood. Expanse : male and female, 

 16-28mm. 



JEyy. — Shaped like a section of a cylinder ; that is, turban-shaped. Sur- 

 face polished but somewhat obscured by an irregular net-work of fine
