TEEAS. 



Teras foliana. (Plate LXI. figs. 5 & 6.) 



Head and palpi oclireouSj the latter projecting not more than the length of the head 

 beyond it^ second joint thickly clothed with ochreous scales which partly conceal the short 

 apical joint J antennse brownish ochreous, slightly pubescent in the male; thorax brownish 

 ochreous in front, pale straw-colour behind, where there is a raised tuft of scales of the same 

 colour. Fore wings — with the costa arched ; apex produced, almost falcate ; dorsal margin 

 nearly straight — pale straw-colour, more or less suffused or reticulated with ochreous brown; 

 a very pale yellowish triangle is preceded by a pale oblique chestnut -brown shade from the 

 middle of the costa, which in some specimens is carried round more faintly on its outer edge ; 

 a narrow pale chestnut-brown line runs along the apical margin; and in some specimens (as in 

 fig. 6) the whole surface of the wings is strongly reticulated with the same colour : cilia at 

 the anal angle straw-coloured, along the apical margin paler : underside glossy pale reddish 

 straw-colour, the costal triangle sometimes indicated in pale staw-colour. Hind wings pale 

 straw- colour, with a faint rosy tinge; cilia and legs lighter. Expanse of wings 19-21 millims. 



Southern extremity of Lower Lake, Lake County, California, June 23rd, 1871. 



This species is nearly allied to Teras contaminana, No. 683 of Staudinger and Wocke's 

 Catalogue, placed by Wilkinson in the genus Dictyopteryx of Stephens, which genus is 

 apparently merged in Teras, Tr., by Heinemann. 



The types figured are both males. There are six males and one female in the Museum 

 collection. 



Teras piilverosana. (Plate LXI. fig. 7.) 



Teras pulverosana, Walh. Gat. Lep. Het. xxviii. p. 291. 

 Sciaphila implexana, Walk. Cat. Lep. Het. xxviii. p. 338. 



Palpi projecting about the length of the head beyond it, thickened in the middle; the 

 apical joint short, depressed. Fore wings — with the costa rather abruptly arched near the 

 base, straighter beyond; the apical margin oblique, slightly impressed below the apex — 

 purplish cinereous, slightly irrorated with fuscous ; paler beneath, with two oblique angulated 

 lines of slightly raised fuscous scales, the first before the middle forming the inner edge of an 

 indistinct purplish-fuscous fascia; the second beyond the middle reaching the apical margin 

 above the anal angle and enclosing the apical portion of the wing, which is indistinctly streaked 

 and mottled with purplish fuscous. Hind wings paler, with a faint purplish tinge, indistinctly 

 speckled transversely towards the costal margin. Type ? . Expanse of wings 19 millims. 



St. Martin's Falls, Albany River. Presented by Dr. Barnston. 



I have thought it desirable to figure this specimen, which, although nearly allied to the 

 common Teras hastiana, Linn., and not in good condition, is probably the type of a smaller 

 and distinct species, having perhaps also a wide range of variation. It is apparently darker 

 than any of the specimens figured by Robinson in plate vii. of the ' Transactions of the
