not many instances of a like nature amongst other species of 

 Lepidoptera ? 



Tiie second argument is, perhaps, of some sh'ght importance, 

 although the five hyaline spots are larger and darker in H. 

 ferornata than H. ornata, and the shape of the orange patch in 

 centre of secondaries is different. During last spring I made 

 special search for H. lyerornata, and was rewarded by the capture 

 of nine male and three female specimens. It is in the males that 

 the differences between the two species are most strikingly evi- 

 denced — they are quite dissimilar both in shape and colouration. 



P7-imaries. — The hind margin is rounded in //. perornata and 

 nearly straight in //. ornata, thus making the apex of the wing acute 

 in the latter insect. In H. ornata the wings present but few and 

 small markings. A chain of three minute apical spots runs at 

 right angles to costa, and three somewhat suffused and more or 

 less distinct irregular markings complete the colouration. A smoky 

 black sexual bar is invariably present. In H. ferornata the wings 

 have larger and more numerous markings. The three apical spots 

 and the other three irregular markings in H. ornata are present in 

 H. ferornata, where the apical spots are larger and more con- 

 fluent, and the other three irregular markings are more deeply 

 coloured, enlarged, and of a different shape. But this insect 

 possesses five additional spots that are altogether wanting in H. 

 ornata — four of them small and running from costa near the 

 apex and parallel to hind margin, the two upper ones being more 

 or less suffused ; and one larger one near the anal angle and just 

 above the inner margin. The sexual bar so noticeable in H. 

 ornata is absent. 



Secondaries. — The anal angle of hind wings is acute in ornata, 

 the hind margin of the wing running abruptly up in a line with 

 the hind margin of the fore wing. In //. ferornata, however, the 

 apex of the hind wing is very obtuse, the hind margin running 

 about parallel with the costa of fore wing (described from 

 specimens ' set ' in the Victorian style). The orange patch 

 in centre of wings is of much the same size as in H. ornata, but 

 slightly different in shape. Both sexes of H. ferornata have the 

 femora and the extremity of the abdomen rufous, but H. ornata 

 shows no sign of any such colour. 



The following notes, descriptive of the eygs and young larvae of 

 the two insects, are taken from my diary for 1895 : — 



17th Nov. — Took a newly-emerged female imago of H. per- 

 ornata, resting on a bush, close to a big plant of Cladium ; wings 

 not properly stiff when taken. 



22nd Nov. — H. ferornata laid eggs, in coi^.finement, on bottom 

 of breeding cage. Eggs 2 mm. in diameter, concave beneath, 

 cream coloured, very much depressed, and hollowed slightly at 

 apex : surface dull and rough, not ribbed. 



22nd Nov.--//. ornata laid eggs on leaves of Cladium. Kggs
