washed with rose-red, especially on costal and external areas ; 

 a greyish outer border : fringe of all the wings cream- coloured, 

 traversed by a grey stripe : body below cream-coloured, 

 femora and tibiae reddish. Expanse of wings 1 inch 2 lines. 



One specimen. This is the first Mecyna of the typical 

 group received from the Hawaiian islands. Mr. Blackburn 

 says of it, " I send a specimen (one of two) bred from larvse 

 found feeding on a tree unknown to me by name, but appa- 

 rently a species of Acacia^ which I have not seen growing 

 elsewhere than in damp ravines at an elevation of 4000 to 

 5000 feet on Haleakala, Maui. A third specimen I took 

 flying by day in the same locality ; it is larger, exp. al. 

 38 millims., ground-colour of front wings as bright yellow as 

 the cilia of hind wing in the specimen sent, otherwise identical ; 

 probably the other sex. The other bred specimen is identical 

 with the one sent, 



" The following is a description of the larva : — Shining 

 black, sparingly furnished with long grey-white hairs ; head 

 and underside dirty grey ; spiracular line bright orange-colour ; 

 three pairs of legs (on three segments next behind head), and 

 five pairs of claspers, all dirty semitransparent grey. Forms a 

 pupa in a silken cocoon." 



The entirely different character of the under surface readily 

 distinguishes this species from its allies. 



Scopariidae. 



18. Scoparia haivaiensis, sp. n. (No. 83). 



Closely allied to 8. exMbitalis of Australia and 8. Icetalis 

 of Europe : primaries above grey, densely speckled with black, 

 crossed near the base by an angulated cream-coloured belt, 

 broadly bordered and sparsely speckled with black ; a has- 

 tate black spot in the cell ; end of the cell filled by a milk- 

 white spot ; a black rhomboidal spot just beyond the cell, a 

 black spot partly surrounded by white scales below the dis- 

 coidal hastate spot ; external third densely irrorated with 

 milk-white scales, which form two ill-defined stripes, the inner 

 one zigzag and discal, the outer one submarginal ; two sub- 

 apical costal spots, a nearly marginal confluent series of un- 

 equal spots, and a large spot on the inner margin near the 

 external angle black ; a marginal chain-like series of small 

 elliptical wdiite spots, bounded externally by a slender black 

 line; fringe sericeous sordid white, tipped with grey and 

 traversed near the base by a black line : secondaries sericeous 

 sordid white like tarnished silver, fringe with greyish outer 

 half and a grey subbasal line : thorax black, spotted with
