scalloped; internal anj^le rdiiiided, and a little within tlie nuddle of the ininT niariiin is a 

 prominent tult otdailc scales: outer edge scalloped. 



Venation: 'I'lie seut)nd and third snbi-oatal vennles are very near each other, the std)(;ostal 

 cell very nari-ow, linear; the fourth subcostal vein arises within the middle of the subcostal ci-ll. 

 The upper braucli of the third subcostal is very short and passes straight to the costa just before 

 tlie apex. The upper discal vein is curved somewhat obliquely inward to the origin of the fifth 

 subcostal venule, then passing very obliquely, and uncurved, to the middle of the discal sjiace, 

 where it meets the lower discal vein, which is perpendicular to the cubital venule from which it 

 arises. The venation of both wings is in fact just as in Schizura. Hind wings a little more 

 pointed at the apex than in Schizura; costa straight, bent down somewhat at the apex; outer 

 edge obliijue, not very full, bent slightly on the first median interspace. 



Legs: Femora buried and concealed in the long scales ot the breast; fore tibia^ densely 

 pilose, presenting a flat ex])anse on each side; the nuddle and hind tibi* with two long sharj», 

 nearly equal spurs. 



Abdomen long, cylindrical, the tip s(juare, scarcely tufted. 



Coloration: Gray with darker streaicsobli([nely 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 with that 

 genus. It only differs in the scalloped fore wings, the rather stouter and shorter palpi, the 

 stronger pectinations of the antenna*, the distinctly scaled pronotal pieces, and the long hairs on 

 the breast; tlie fore wings are also longer and narrower than in Schizura, and the outer edgemore 

 oblique, while the inner edge has a slight tuft. Our generic name, Xylinodes, was given to it from 

 the resemblance of the markings of the fore wing to the noctuid genus Xylina, in which the fore 

 wings are also decidedly slashed. The name lauassa should be dropped, since it was proposed by 

 JMiinster in 1S3I) for a genus of sharks (Beitr. Petref, i, 1S3'J). Mr. Druce (Biol. Ceutr. Amer., 

 p. 242) points out the fact that lanassa is preoccupied, and apparently ignorant that I had pro- 

 posed the name Xylinodes for tlie genus, changed the generic name to Pliya. 



^(/(/.—"Globular and smooth" (Dyar). Further observations are needed. 



Cocoon. — A regularly oval thick earthen cell lined with silk, the larva transforming either on 

 the surface or within the earth. 



Larva. — Head bilobed: on first abdominal segment a hump supporting a large double tuber- 

 cle, and on the eighth segment a decided hump bearing two small x)iliferous warts. End of body 

 and anal legs raised, much as in Schizura. Freshly hatched larva: ''Tuliercles on first abdominal 

 segment brown; anal feet partly aborted."' (Dyar.) 



GeoijrapMcal distribHtioii. — This genus is peculiar to the New World, extending through the 

 Appalachian and Austroriparian into the eastern portion of the Campestrian subprovmce, as far 

 Avest as Colorado, South Dakota, and Salt Lake, Utah. This genus also occurs in the Mexican 

 (Sonoran) subprovince as Mr. H. Edwards has described (Ent. Amer, i. p. 129). Janassa laciiiiosa 

 is from Jalapa (Schaus) and Mazatlan.
