﻿42 LEPIDOPTERA INDIGA. 



the outer margin towai'ds anal angle very slightly paler, and showing just the faintest 

 trace of the discal band from the costa, which is present in Isa ; the marginal dots and 

 streaks present, but hardly visible. Hindwing hair-brown ; a discal series of whitish 

 spots between the veins, the four upper ones round and equal-sized, the fifth in the 

 second median interspace larger and diffused inwardly, the one in the space below 

 elongated into a streak, the one in the submedian interspace still longer and bifur- 

 cated outwardly ; some obscure streaks on the abdominal margin above the anal 

 angle. The usual whitish spots in pairs iu the margin. Underside, Both wings 

 paler, the inner margin of the forewing pale purple, the marginal streaks and spots 

 more distinct than above. Hindiuing with a discal series of even round whitish spots, 

 somewhat blurred at the anal angle, marginal spots as above. Apparently mimics 

 the Euplfeine butterfly Pe7?oa AlcafJwe. 



Fourth Form (Plate 204, figs. 1, la). Upperside brown, the basal area blackish. 

 Forewing with very faint traces of a whitish-speckled elongated streak between the 

 basal interspace of the middle and lower veinlets, beyond which are three lower sub- 

 marginal whitish-speckled lunate spots situated between the upper median and 

 submedian, below which is a similar elongated streak before the posterior angle, and 

 beyond a complete marginal series of small distinct white spots. Hindwing with a 

 lower discal series of white-speckled spots which partially coalesce with a submarginal 

 row of more distinct spots, beyond which is a marginal row of prominent small white 

 spots. Underside with an ill-defined discal series of whitish spots merging into more 

 distinct white rounded submarginal spots, beyond which is a marginal row of pro- 

 minent white spots. Underside uniformly brown, with all the spots as on upperside 

 more distinctly defined. 



Expanse, 3j^o inches. 



Fifth Foem. — Nyctelitis, Doubleday (Plate 204, fig. 1, b). Upperside purplish 

 brownish-black. Forewing with the apical area broadly suffused with blue ; a 

 marginal series of small narrow oval purpurescent-whitish spots, disposed in pairs 

 between the veins, and a less defined series of similar-coloured posteriorly-disposed 

 submarginal rounded spots. Hindwing with the discal and outer interspaces broadly 

 between the veins pale purpurescent-whitish, crossed by a submarginal shade and 

 broken by a marginal series of dentate marks of the dark ground colour. Underside 

 paler than above, with all the markings more clearly defined. A mimic of the 

 Euplgeine butterfly (?) Penoa Alcathoe or (?) Trepsichruis Linnsei, 



Expanse, 2>\ inches. 



Sixth Form. — Cinnamomeus, "W. M. (Plate 204, fig. 1, c, d). " Upperside. Fore- 

 wing purplish black-brown, darkest at the base and along the edges ; glossed with
