NOTES ON GLUPHISIA AND OTHER NOTODOXTIDAE. 



-II. 



BY A. S. PACKARD, 



The structural differences between 

 G. trili neat a and G. ivrightii. var. 

 slossoniac, and which at first led me to 

 think them generically distinct, are the 

 following : 



A 9- The head is remarkably small, much 

 more so than in G. trilineata; and is loosely 

 scaled in front. The antennae are pectinated, 

 the branches a little longer than in $ trili- 

 neata. The palpi are short, small, depressed, 

 with loose scales; and they are not quite so 

 large and long as in trilineata. The thorax 

 differs from that of Gluphisia trilineata in 

 having a median dorsal tuft. The legs are 

 hairy, and much as in trilineata, the tarsi 

 being ringed with gray and darker scales. 

 The fore wings are narrow but with the 

 costa unusually convex, much more so than 

 in trilineata; the apex is somewhat rounded, 

 but much as in trilineata; the outer edge is 

 very faintly excavated below the apex. The 

 hind wings are of the same shape as in trili- 

 neata. There are six branches of the sub- 

 costal vein : branch 1 is longer than in 

 trilineata and ends half way between end of 

 costal vein and end of branch 2 of the sub- 

 costal ; the costal area is wider towards apex 

 than in trilineata. The 5th and 6th branches 

 are nearly as in trilineata. The lower discal 

 vein is not so much bent as in the last 

 named species. The three median veins are 

 nearly as in trilineata, but the 2d median 

 space is wider than in that genus. The 

 submedian vein is represented by a simple 

 fold. In the hind wings the two branches of 

 the subcostal are much longer than in trili- 

 neata, the space between them being long and 

 narrow, in trilineata short and broad triangu- 

 lar. The discal veins are, taken together, 

 slightly curved, where in trilineata they make 

 a decided angle at the origin of the indepen- 

 dent vein ; and there is a common origin of 

 the lower discal. and of the two median

veinlets. The second median interspace is 

 much wider than in the species of the other 

 section of the genus. The submedian vein is 

 represented by a simple fold. 



G wrightii var. slossoxiae. — Bodv and 

 wings pale ash-gray ; the prothoracic segment 

 colored as the head, but the rest of the thorax- 

 is dark brown, the median thoracic tuft also 

 dark brown. Fore wings black-brown on 

 basal one-fifth ; this portion sending out five 

 sharp tooth-like projections along the sub- 

 costal, submedian and internal veins. A 

 broad distinct median oblique band, with ir- 

 regular lobulate edges, and widening on the 

 costa; it encloses a very distinct discal trian- 

 gular white spot, the apex pointing outwards. 

 A submarginal broken row of dark spots 

 arranged much as in Gluphisia trilineata. 



Hind wings with no markings, but at the 

 inner angle is a faint short curved dark band, 

 edged externally with white, but not reaching 

 beyond the middle of the submedian space. 

 Fringe concolorous with the wing, but 

 checkered with small black spots. 



Wings beneath much as in Gluphisia trili- 

 neata: the black band is faint, its outer edge 

 indicated on the costa by a dark spot. Ex- 

 panse of wings, 3S mm: length of bodv. 15 

 mm.

 Cal. This does not seem to differ from 

 JV. gibbosa. The 9 has a paler body 

 and wings, the fore wings are more 

 pointed, and as in many Pacilic coast 

 moths, it is larger than the eastern form 

 of gibbosa. On examining my type of 

 N. doubledayi in the collection of the 

 American entomological society I find 

 that it is not even a variety of gibbosa. 

 It only differs in having the underside
