Fore wings rounded at the apex, with the base yellowish, inter- 

 sected longitudinally with obscure streaks of greyish scales ; beyond 

 the yellowish basal patch is a distinct yellowish \J, universally mar- 

 gined with whitish grey ; beyond it the apical half of the wing is 

 whitish grey irrorated with fuscous scales, with a slight yellowish 

 oblique streak immediately before the pale extreme apex ; about 

 the anal angle is a series of four distinct, shining, whitish, steel- 

 coloured, metallic marginal dots, each surrounded by a separate deep- 

 black border which is wider above than below them ; above the outer 

 spots are some bluish metallic scales at the base of the greyish 

 fuscous cilia ; underside unicolorous brownish. 



Hind wings brownish fuscous. 



Expanse 13 millim. 



Eight specimens taken, July 15, 1871, Shasta county, California. 



Genus Heliodines (Stainton). 

 Heliodines extraneella, sp. nov. (Plate XXXVI. fig. 15.) 



Alis anticis cupreo-aurantiacis, basifusca, maculis tribus costalibus 

 una dorsali argenteo-metallicis, maculis duabus triangidaribus 

 (una costali ante apicem, altera ante angulum analem) niveis, 

 omnibus partim niyro succinctis, ciliis cupreo-metallicis. 



Head, face, and palpi shining metallic greyish fuscous. Antenuse 

 fuscous. 



Fore wings bright reddish orange, with a small fuscous basal patch 

 slightly produced above the fold ; three small silvery metallic costal 

 spots followed by a triangular snow-white spot before the apex ; one 

 silvery metallic dorsal spot situated very slightly nearer to the base 

 than the first costal spot, from which it is separated only by a few 

 black scales on the fold ; it is followed by a triangular snow-white spot 

 before the anal angle ; all the spots are more or less surrounded by 

 scattered black scales ; the apex and apical margin, with the base of 

 the cilia, shining metallic bronzy cupreous. 



Hind wings pale fuscous with slightly darker cilia. 



The underside of all the wings shining bronzy, a bright orange 

 spot on each side of the thorax beneath at the base of the fore

This species agrees with the genus ^tole of Chambers (Can. Ent. 

 vii. p. 173) in the length of the tongue, as well as in the rather 

 narrowly produced apex of the fore wings, the only points in 

 which it differs in external appearance from the genus in which 

 I have ventured to place it. Mr. Stainton, who founded that 

 genus (Ins. Brit., Lep. Tin. p. 243) for the reception of a single 

 species. Tinea roesella, Linn., writes to me that he " should be 

 disposed to refer the insect " of which I sent him a specimen " to 

 Heliodines." Without destroying one of my hmited number of
