320 LORD WALsiNGHAM ON [Feb. 15, 



aud four bright metallic steel-white dots set in an elongate black , 

 patch above the anal angle. The first steel-grey streak, which is 

 much dilated towards the base of the costa, reaches obliquely to the 

 outer extremity of a steel-grey patch at the base of the dorsal mar- 

 gin ; beyond it, before the middle of the wing, is a narrow, straight, 

 pale steel-grey fascia with rather darkened margins ; shghtly be- 

 yond the middle of the costa is another pale steel-grey mark, ex- 

 panding immediately below the costa and diffused into a pale greyish 

 ochreous patch, much occupied by slender, transverse, blackish 

 fuscous streaks ; beyond this, again, is a bright steel-blue streak, 

 whitish towards the costa, and reaching to a whitish interruption in 

 the fuscous cilia above the middle of the apical margin ; a shorter 

 and paler steel-grey streak lies immediately before the apex, but does 

 not quite reach the apical margin. The costa is narrowly shaded 

 with blackish fuscous, especially beyond the middle. The elongate 

 black patch above the anal angle, containing four steel-white metal- 

 lic dots, stretches from the dorsal margin before the anal angle to 

 near the middle of the apical margin, in which direction it is some- 

 what attenuated ; there are two small black marginal dots below it. 

 Underside with two white costal streaks towards the apex, preceded 

 by two white costal spots, and with a short white streak from the 

 apical margin. 



Expanse 17 miUim. 



This species differs from Glyphipteryx loricatella (Tr.), in the 

 more rounded hind wings, which are not indented beyond the ab- 

 dominal angle, as well as in the absence of brilliant metallic endings 

 to the costal streaks, which, however, are the same in number and 

 position. It differs also in the absence of two white dorsal spots, 

 and in the black patch being narrower and running obliquely instead 

 of parallel to the dorsal margin. The hind wings are paler, and the 

 fore wings a lighter orange-colour than in the European species. 



In general appearance it exhibits some approach to some of the 

 Hydrocampidce. The small head and the form of the palpi, as well 

 as the character of the ornamentation, cannot fail to remind us of 

 Cataclysta (H.-S.) and some allied Asiatic genera. 



I have met with only one specimen, taken on Mount Shasta, Cali- 

 fornia, in August 1871, and shghtly denuded at the time of its 

 capture.
