no.1645. REVISION OF CERTAIN NOCTVIDM— SMITH. 229 



Habitat. — California : Sonoma County, Los Angeles County, in 

 November; San Louis Obispo in February; San Francisco, Behr. 



I have a specimen of salicis given me by Doctor Behr himself, and 

 I have seen the type of his rosw. My impression is that he described 

 the sexes of the one species, but that is not certain; at all events 

 there are no two closely related forms on the Pacific coast so far as 

 the material in my hands indicates. It is not even absolutely certain 

 that we have a species distinct from the eastern lunata, although that 

 I believe. Superficially, if the Californian examples were mixed 

 with a lot of eastern material they might attract attention as being 

 less well defined than the ordinary run of examples, but would not 

 be suspected of representing a distinct species. Structurally, the 

 differences are hardly greater. In the" male the lateral pieces are 

 identical in type and the differences in detail are not greater than 

 I might consider within specific range. The uncus, however, is quite 

 markedly different and is drawn out to a slender point unlike any 

 lunata that I have seen. In the female the differences are somewhat 

 greater and can be best appreciated by a comparison of the figures. 



It may be that when both eastern and western forms have been 

 fully compared in all their stages, the question of their specific 

 identity can be more easily determined.

Ground color dull smoky brown. Head concolorous, sometimes 

 with a dark median line. Collar darker at base and below tip, leaving 

 a paler brown central line, often gray tipped: no distinct black line 

 in any specimens. Thorax with alternate darker and paler lines more 

 or less distinct, sometimes gray. Abdominal tufting small. Prim- 

 aries with all the lines usually well defined. Basal space usually a 

 little darker. Basal line brown or blackish, geminate, usually well 

 defined. T. a. line geminate, the component lines quite widely sepa- 

 rated, the inner less obvious, outer black or blackish, irregular, a little 

 outcurved but on the whole inwardly oblique. Just beyond this line 

 rs usually a little the palest area in the wing, in the males usually and 

 in the females often powdered with gray. Beyond this the median 

 space is crossed by three more or less obvious undulated transverse 

 lines, of which two are nearly upright, while the outer is curved 

 around the outside of the reniform. T. p. line narrow, thread-like, 

 black or brown, irregular, broadly and rather squarely exserted over 

 cell, just a little indented opposite reniform, oblique rather than in-
