178 [January, 



under-surface sericeous whitey-brown ; wings washed with grey to beyond the middle, 

 where there is a paler discal band followed by a darker external border ; the whole 

 surface indistinctly striated with grey ; diffused blackish discocellular spots. 



Expanse of wings, 39 mm. 



" Occurs on tree-trunks at an elevation of about 2000 feet, on 

 Lanai ; very hard to catch, as it flies wildly before one can approach 

 near enough to its resting-place, and the ground is almost too rough 

 to attempt pursuit : September." — T. B. 



But for its different ground-colour and distinctly striated upper 

 surface, I should have supposed this to be the male of S. corticea. 



PYRALES. 



2. Scopida litorea, sp. n. 



Sericeous creamy-whitish ; palpi very long, curved and deflexed ; primaries 

 irrorated with ferruginous, crossed at basal third by an irregularly sinuated black -' 

 spotted greyish line ; two parrallcl discal series of black spots foi'ming a wide arch 

 to the first median branch, where they turn outwards at an acute angle and then 

 again transversely to inner margin ; discoidal spots ferruginous, ill-defined ; second- 

 aries with a spot at the end of the cell and an arched denticulated discal line, dark 

 grey ; a second paler grey line nearer to the outer margin ; all the wings with a 

 marginal series of minute blackish points, which in the primaries are continued 

 along the costa to the end of the cell ; wings below slightly sordid ; primaries with 

 the markings indicated in grey ; the reniform spot outlined in grey ; secondaries with 

 all the markings represented by black dots ; otherwise much as above. 



Expanse of wings, 14 — 18 mm. 



" Occurs on the sandy sea-shore at a place called Mauna Lea 

 (Lanai), flying over flowers : September." — T. B. 



Orthomectna, gen. 7iov. 



Allied to 3fecyna, from which it differs in its less prominent eyes, 

 less pointed and loosely scaled palpi ; the shorter costal margins to 

 the wings, the less oblique and straighter outer margin of the prim- 

 aries and smaller secondaries. Type " Mecyna'" exigua. 



A second species, having similar structural characters to those of 

 M. exigua, being now sent (with additional examples of that species), 

 I feel satisfied that the difference between them and typical Mecyna 

 warrant their separation from that genus. 



3. Orthomecyna albicaudatn, sp. n. 



Primaries above golden-cupreous'; sometimes with an abbreviated irregular 

 blotch representing the central band over the end of the cell from costal margin to 

 median vein, below which it is indicated only by one or two small isolated spots, 

 sometimes wholly wanting ; a more or less defined angular blackish lunule on the 

 discocellular s ; external area washed with brown, which, however, only becomes dis-
