than the ground-colour ; a slightly irregular vermilion-red 

 belt (a little narrower towards the costa) just beyond the 

 middle of the wnng ; no trace of any white spot at the anal 

 angle ; costal border paler than the ground-colour ; fringe 

 white towards the anal angle, rose-coloured along the abdo- 

 minal margin : body above dark olivaceous ; the head, 

 shoulders, and tegular bordered with sulphur-yellow ; antennee 

 black, tipped witli snow-white, ferruginous internally : abdo- 

 men with lateral white and black basal markings, nearly as 

 in D. euphorhicp^ but narrower ; three last segments bordered 

 at the sides behind by narrow transverse cream-coloured 

 spots ; lateral margins dull rose-coloured. Wings below brick- 

 red, crossed beyond the middle by two subparallel curved 

 black lines (abbreviated in the secondaries) ; outer border 

 rosy brown, v/ith zigzag inner edge ; discoidal area of prima- 

 ries blackish, partly obscured towards the base by dull rosy 

 hairs : body below pale rosy ferruginous ; legs and palpi pale 

 greyish brown, the base of the palpi and anterior tarsi 

 whitish. Expanse of wings 2 inches 10 lines. 



One specimen of this very distinct species was sent in a 

 separate box. Mr. Blackburn gives the following description 

 of the larva : — 



^^ Larva. Pale green (belly whitish), sparingly dusted with 

 white ; dorsal and spiracular lines whitish, but rather obscure ; 

 first segment («'. e. the one behind the head) obscurely suifused 

 with red ; spiracles pink, with a crimson centre ; head and 

 legs green ; claspers green, tipped with crimson ; horn short 

 and warty, black above, red beneath ; head small 5 second 

 and third segments behind the head much distended. 



" Another individual was as follows : — Greenish grey, witli 

 a sooty appearance, sparingly sprinkled with rather large 

 white spots ; underside green ; dorsal line yellow, very con- 

 spicuous ; spiracular line white ; spiracles yellow, with the 

 centre dull orange ; subspiracular line whitish, but very 

 indistinct, excepting on last segment, where it forms a con- 

 spicuous white line on either side, converging to the horn. 

 There is a general tendency in this form of the larva to a 

 mauve-coloured suffusion in various parts of the body, which 

 is very conspicuous when the larva is about half-grown. 



" The two forms of larva described produced identical 

 moths, though, 1 think, diiferent sexes. 



" I have taken it on several different plants (none of them 

 known to me by name) in different mountain localities in 

 Oahu. The imago flies by day in hot sunshine about flowers, 

 and is also attracted by light in the evening."
