164 THE CANADIAN ENTOMOLOGIST 



faint pale shading at anal angle. Beneath black-brown shaded with pale 

 greenish with an even broad, green, marginal band on primaries and a narrower 

 irregular one on secondaries: primaries with traces of the dark lines of upper 

 side: secondaries with large discal dot and faint median and postmedian lines; 

 fringes as above. Expanse 42 mm. 



Holotype — 1 cf, Vancouver, B.C., April 22, (Bush) in National Collection 

 Ottawa. 



Paratype — 1 cf , Vancouver, B.C., April 16, in same collection. 



Genitalically deceptiva is so close to the eastern jocosa as to almost warrant 

 it being treated as a geographical race; on account of certain small differences 

 in the uncus, combined with the much greater size of the insect I treat it for the 

 present as distinct. 



The species is more robust than columbiana and lacks the suffused dark 

 and pale shades in the subterminal area, the secondaries are also, as alread) 

 mentioned, much deeper in colour. The genitalia of the two species are of th( 

 same general type, but the armature of the aedoeagus at once separates them 

 I doubt whether the generic term Momophana, proposed for comstocki will hole 

 as distinct from Feralia: the separation was made by Grote on the size of the 

 eyes, but this appears to vary in individual specimens of a single species: at 

 all events columbiana seems not out of place in Feralia on genitalic charac- 

 ters. I have, however, at the present time no males of comstocki for examina- 

 tion and must, therefore, leave the question of its generic position, as well ag 

 its relation to cohimhiana, open. 



GeOMETRID/E. 



Larentiinse. 

 Orthonama evansi, sp. nov. 



Male antennae rather lengthily ciliate: palpi, head and thorax light ochreous 

 sprinkled with rusty brown: abdomen ochreous with a double dorsal row of 

 black dots. Primaries light ochreous with veins outlined in rusty brown, 

 especially prominent in subterminal area: a broad band of purplish gray crosses 

 the middle of the wing, broadest at costa, where it is bent somewhat outward; 

 the inner edge is formed by an upright brown line, the outer edge is bordered 

 by a similar line, strongly outcurved at costa and then somewhat inwardly 

 oblique and very faintly crenulate to inner margin: a discal spot surrounded by 

 a somewhat paler shade is situated near the inner edge. Between this median 

 band and the base of wnng are some half-dozen waved rusty-brown upright lines, 

 the most prominent, representing the t. a. line, being geminate, white-filled 

 and with strong outward tooth below cubitus. Beyond the median band the 

 pale subterminal area is crossed by two crenulate brown lines, arising from a 

 diffuse costal shade of similar colour and in course parallel to the outer margin 

 of the band; t. p. line geminate, inner line deep brown, outer lighter, white- 

 filled, crenulate, parallel to the preceding lines, followed by a rusty-brown 

 shade, most conspicuous opposite cell, this shade being bordered outwardly 

 by a crenulate brown s. t. line: terminal space shaded with light-gray with 

 geminate black terminal points and a dark brown oblique apical dash extending 

 from apex of wing to the brown subterminal shade. Secondaries pale with
