5 & and 5 9.— Somewhal allied to R. lacustrata in form; but the palpi 

 are of unusual length, rather slender, and the hind wings arc a little more 

 produced toward the apex. Body and fore wings brown; palpi blackish, 

 tipped at extreme end with white. Head gray. Fore wings with numerous 

 finely-scalloped dark lines; about six such linos: the median, dark, broad 

 band is loss distinct than- usual, without the usual angle in the discal space. 

 but wilh a large, distinct, Mack, discal dot; beyond the edge of this hand, 

 which has about nine scallops, is a whitish, narrow hand, with a faint median. 

 scalloped, dark line: beyond is a large black costal blotch, and a second one 

 below, opposite the discal dot. and limited beyond by the usual zigzag, white, 

 submarginal line: a marginal row of (dose-set black triangles. Hind wings 

 whitish, usually without any markings, except the marginal row of conspicu- 

 ous, black, close dots; beneath marked much as usual in lacustrata and allied 

 species, ike wings being clouded, with the lines faintly reproduced, and two 

 faint lines on the hind wings, with a discal dot. 



Length of body. <? . 0.40, <? , 0.40; of fore wings, <?, 0.45-0.52, 9, 0.52: 

 expanse of wings, 0.90-1.10—1.20 inches.

1 tillering from all the other species by the scalloped edge of the median 

 hand, which is less black than usual, this species reminds one of Ochyria 

 designata in the two blackish patches near the apex. The two White Mountain 

 specimens have the hind wings darker, with traces of two lines, and are also 

 smaller than the Californian and Vancouver Island examples, the fore wings 

 measuring <».4l> inch; and the fore wings are a little blunter. It may prove 

 to be identical with some European species. Those from Vancouver Island 

 have longer, more pointed wings, and are whiter than Californian examples, 

 and expand a line more. 



This species lias been identified from a drawing of Walker's type made 

 by Mr Willis.
