NONAGRIA ALAMEDA, n. sp. 



Ground color dull smoky red-brown. Head and thorax concolorous , 

 immaculate. Primaries in the male dark brown; in the female lighter, 

 with a somewhat yellowish tinge. No contrasting maculation in either 

 sex. Veins narrowly black-marked. T. a. line obsolete in the ^; in 

 the 9 ma y be entirely wanting or may be traceable for its full course as 

 a narrow, smoky line, upright as a whole, outcurved in the interspaces. 

 T. p. line a series of venular dots; very small black dots in the male; 

 better marked, with larger dots, emphasized by white scales, in the 

 female. A narrow, dusky, terminal line, followed by a pale line at the 

 base of the fringes. Reniform scarcely traceable in the <J\ obscurely 

 marked and yellowish centered in the $. Secondaries yellowish, with 

 an obscure extra-median line in the female ; darker with a smoky tinge 

 in the male. Beneath yellowish with a smoky tinge; powdery; both 

 wings with an exterior dark line or shades, primaries with the disc 

 blackish. 



Expanse. Male, 1.28-1.48 inches 32-37 mm. 



Female, 1.48-1.56 inches = 37-39 mm. 



Habitat. Alameda County, California, July and August; 

 red No. 231 (A. Koebele). 



Type. No. 6807, U. S. National Museum. 



A series of eight examples, equally divided as to sex, is tinder 

 examination, and there is a greater similarity between the sexes 

 than in any previously described species. The males are as dark 

 as any subflava and might even be mistaken for them except for 

 the somewhat greater size and more sharply black-fined veins. 

 The females range larger but not strikingly so, and they differ 

 from the males chiefly in the lighter coloring throughout. The 

 dotted t. p. line is greatly reduced here in both sexes, and in this 

 point the species is also characteristic. In the head structure 

 atameda resembles subjlava closely save that, viewed laterally, 

 the front does not extend so far beneath the process and the lateral 

 edges are differently serrated. So, in the character of the female 

 lateral structures, the resemblance is also to subjlava; in fact the 

 two species are closely related and should be found to have closely 

 similar habits.
