Habitat. Rye, Westchester Co., N. Y., July 31 (Bird); 

 Buffalo, N. Y., July (Kellicott) ; Newark, N. J. (Buchholz) ; 

 Brockport, N. Y. (Bruce); Webster, N. H. (Goodhue) ; Chi 

 cago, 111., Champaign, 111., July 31, at electric light (Forbes) ; 

 Los Angeles Co., Cal., in October (Koebele) ; Kittery Point, 

 Maine (Thaxter) ; Fresno, Cal. (E. A. Schwarz). 



The above localities are represented in the series of 17 speci 

 mens now before me. It is quite probable that the species will 

 be found throughout the United States wherever the food plant 

 (Typka] occurs. Florida should be added to the list of localities 

 given, as the type of permagna was received from that State. 

 The life history of the species is given by Dr. Kellicott in Volume 

 V of the Bulletin of the Buflalo Society of Natural Sciences, and 

 this shows one brood only, with a hibernation in the egg stage. 



The general line of variation has been already referred to. The 

 Californian examples are paler, and the secondaries have a rosy 

 flush. They look different, but I have found it impossible to get 

 any constant differential features. In the female the lateral in 

 ferior pieces have the tip distinctly emarginate, and this feature 

 is constant and characteristic of the species. 



The frontal process in this species is very long actually and in 

 comparison with lhat of the other species, and it is slightly 

 notched at the tip. Seen from the top the lateral margins are 

 denticulate and a little flattened ; seen from the side, the inferior 

 portion of the front is extended for only a short distance beneath 

 the process. In the male the projection seems, on the whole, 

 somewhat less prominent than in the female, but there seems also 

 to be a little individual variation in this respect.

Nonagria subflava Grote, Bull. U. S. Geol. Surv., vi, p. 583, 1882. 

 Ground color yellow luteous in the female, reddish brown in the male, 

 varying somewhat in the specimens. Head and thorax concolorous with 

 the primaries, without obvious markings. Primaries somewhat powdery 

 in both sexes. In the male the veins are black or smoky, with some white 

 interrupting scales, median vein scarcely more prominent than the others. 

 T. p. line a series of small venular dots tending to become lost. Terminal 

 space vaguely darker in some specimens. Reniform a vague, somewhat 

 lighter shade. In the female the contrasts are much better marked ; the 

 median vein is conspicuously darker and usually has a smoky shade accom 

 panying it ; most obvious at base and at the end of the median vein. The 

 submedian vein is also more or less well marked basally. The terminal 

 space tends to smoky brown, blackish on the veins, the apex nearly always 

 free. T. a. line marked by venular dots in most specimens, but sometimes 

 wanting. T. p. line nearly always obvious as a complete series of black
