scalloped; internal an^le rounded, and a little Avithiu the middle of the inner margin is a 
prominent tuft of dark scales; outer edge scalloped. 
Venation: The second and third subcostal venules are very near each other, the subcostal 
cell very narrow, linear; tlie fourth subcostal vein arises Avithin the middle of the subcostal cell. 
Tlie upper branch of the third subcostal is very short and passes straight to the costa just before 
the apex. The upper discal A'eiu is cuiwed somewhat obliquely inward to the origin of the lifth 
subcostal A^enulo, then i)assing A-ery obliquely, and uncurA'’ed, to the middle of the discal space, 
Avhere it meets the Ioaax'i- discal vein, which is perpendicular to the cubital A^enule from Avhich it 
arises. The venation of both Avings is in fact just as in Scliizura, Ilind wings a little more 
pointed at the apex than in Schizura; costa straight, bent down somewhat at the apex; outer 
edge oblique, not very full, bent slightly on the hrst median interspace. 
’ Legs: Femora buried and concealed in the long scales of the breast; fore tibim densely 
pilose, i)resenting a flat expanse on each side; the middle and hind tibun with two long sharp, 
nearly equal spurs. 
Abdomen long, cylindrical, the tip square, scarcely tufted. 
Coloration: Gray Avith darker streaks obliquely crossing the costa. The single species of our 
fauna is more slashed and streaked than any of our other Notodontians. 
This genus, both in its larval and adult characters, is so near Schizura that it seems scarcely . 
necessary to regard it as separate, and it may ultimately be found best to unite it Avith that 
genus. It only differs in the scalloped fore Avings, the rather stouter and shorter palpi, the 
stronger pectinatioixs of the anteniiie, the distinctly scaled pronotal i)ieces, and the long hairs on 
the breast; the fore Avings are also longer and narrower than in Schizura, and the outer edge more 
oblique, while the inner edge has a slight tuft. Our generic name, Xylinodes, aa'us given to it from 
the resemblance of tlie markings of the fore wing to the noctuhl genus Xylina, in Avhich the fore 
wings are also decidedly slashed. The name laiiassa should be <lropped, since it Avas proposed by 
J\Iiiuster in 1839 for a genus of sharks (Beitr. Fetref., i, 1830). Mr, Driice (Biol. Ceiitr. Amer., 
j). 212) ])oiuts out the fact that lanassa is preoccupie<l, and apparently ignorant that I had pro- 
posed the name Xylinodes for tlie. genus, changed the generic name to Phya. 
jfjgg ^ — ‘‘Globular and smooth” (Dyar). Further observations are needed. 
Cocoon . — A regularly oval thick earthen cell lined Avith silk, the larva transforming either on 
the surface or AAMthin the earth. 
Larva. — Headbilobed; on lirst abdominal segment a hump supporting a large double tuber- 
cle, and on the eighth segment a decided hump bearing tAvo small ixiliferous Avarts. End of body 
and anal legs raised, much as in Schizura. Freshly hatched larva: “Tubercles on first abdominal 
segment broAvn ; anal feet partly aborted.” (Dyar.) 
Gcographieal distribution . — This genus is peculiar to the XeAv AYorld, extending throngli the 
Appalachian and Austroripariau into the eastern portion of the Campestrian subprovince, as far 
Avest as Colorado, South Dakota, and Salt Lake, Utah. This genus also occurs iu the Mexican 
(Sonoran) subproAduce as Mr. II. Edwards has described (Eiit. xVmer, i, p. 129). Janassa laciniosa 
is from Jalapa (Schaus) aud Mazatlau.
