Larva. 

 Thaxici; C:iu. Ent., xxiii, p. 34, Feb., 18111. 



Moth. — One S . Antenna? well pectinated to tin; tijis; \)a\[)i passin.n' beyond the front, longer 

 than in X. angulosa ov frrrnginea. IJody and fore wings oulieron.s gray, witli iilack lines and 

 liatches. Collar edged with black; over the scntelliini a transverse wliite stripe, beliind which is 

 a bhick patch. 



Fore wings quite broad, shorter and broader than in any Lophodouta or Notodonta, and pointed 

 at the ape.K. On base of wing, at origin of cubital vein, a short silvery white stri])e, from which 

 a black line passes along the whole cubital vein, this and its branches being black, aud the l)ase 

 of the wing iu front of the line dusky black. Wing covered by two white lines more or less edged 

 with black, the linear black discal mark being nearest to the extradiscal line; inner (extrabasilar) 

 line much curved and dentate, sending a tooth inward along the internal vein. Extradiscal line 

 much curved outward opposite the discal mark and but slightly scalloped. Three subapical black 

 iutervcnular black slashes, one in nearly each space behind, that in the second <;ubital space 

 being large and distinct. The .space between the two Hues filled iu behind the third cubital venule 

 with black, reheved by fawn-bi'own on each side of the internal vein. Tuft on inner edge black. 

 Fringe fawn color, with venular spots. Hind wings sordid white; no discal mark or extradiscal 

 line. Beneath, sordid white; fore wings with faint discal mark and extradiscal line; hind wiugs 

 ■with two nearly parallel ol)lique dusky costal stripes on outer half of the wing. 



Expanse of wings, i 40 mm.; length of b(xly, r? 16 mm. 



Larva. — "Length, 30 to 40 mm.; very robust; tapers slightly at either extremity; most 

 noticeably posteriorly. Anal legs moderately long. Color green, more or less lined and dashed 

 with yellowish white and very thickly and irregularly longitudinally dotted with dull winered dots, 

 more numerous along lower lateral margin, coalescing into a more or less distinct line; troplii, 

 thoracic feet, and tips of abdominal prolegs more or less marked with the same red color. Head 

 with a broad central yellow area bordere<l with reddish brown, tapering toward posterior margin 

 and continuous with very characteristic yellow stripe along the dorsum of the body, which is also 

 bordered, though narrowly, with wine-red, and more or less dotted aud suffused with same color, 

 particularly on segments 1, 5, and 6. This stripe narrows rapidly on first segment, is uniform 

 on second, widens very considerably to fifth, extending down on the side, narrows again to the 

 posterior margin of the seventh, whlens gradually from anterior margin of eighth, and narrows 

 again slightly toward tip of anal plate. In the broadest portion, on segments 3-7 aud 8 to tij). the 

 central space is green, irregularly lined, and dotted with whitish. 



"Tlirce specimens from Atlanta, Ca.; two from St. Louis, Mo., and onefrom Fortress Monroe, 

 Ya." (Riley MS.) 



Pupn. — " Similar to that oi L.ferriujinca, but somewhat more tapering, and projecting at the 

 tip in two dorsally directed, very strong, short widely separated spurs. (Anterior half of pupal 

 shell wanting.") (Riley MS.) 



MahiU. — Larva occurs in September; the moths in May, June, and July. (Riley MS.) 



Food plant. — Quercus. (Thaxter aud Riley.) 



This is evidently Tepper's DryHobia tortuosa and HerrichSchaeff'er's species, as I have 

 believed for several years past, aud now feel sure after seeing specimens of it in Mr. Edwards's 

 collection.
