 Thaller, Can. Ent., xxiii, y>. 34, Feb.. 1891. 



^[oth. — One (? . AiiteiintB well pectinated to the tips; ]iiilpi itassinj;- heymid the front, lonjjer 

 than in L. angiiloaa m- fcrriKjinea. Uody and fore wings ocheroiis gray, with black lines and 

 patches. Collar edged with black; over the scutelluni a transverse wliite stripe, behind which is 

 {I black i)atcli. 



Fore wings (jnite broad, shorter and broader than in any Lophodoiita or Notodonta, and pointed 

 at the apex. On base of wing, at origin of cubital vein, a short silvery white stripe, from which 

 a black line passes along the whole cubital vein, this and its branches being black, and the base 

 of the wing in 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 ninch curved aiul dentate, sending a tooth inward along the internal vein. Extradiscal line 

 much curved outwar<l oi)posite the discal mark and but slightly scallojied. Three subapical black 

 iutervenular black slashes, one in nearly each space behind, that in the second cubital space 

 beiu"- large and distinct. The sjjace between the two lines tilled iu behind the third cubital venule 

 with black, relieved by fawn-brown on each side of the internal vein. Tuft on inner edge black. 

 Fringe fawn color, with venular spots. Ilind wings sordid white; no discal mark or extradi.-^cal 

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

 ■with two neaily parallel oblique dusky costal stripes on outer half of the wing. 



Expanse of wings, $ 40 mm.; length of body, <? IG mm. 



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

 uoticeablv i)i>steriorly. Anal legs moderately long. Color green, more or less lined and dashed 

 with yellowish white and very thickly and irregularly longitudinally dotted with dull wine-red dots, 

 more numerous along lower lateral margin, coalescing into a nu>re or less distinct line; trophi, 

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

 wirh a broad central yellow area bordered with reddish brown, tapering toward posterior margin 

 and continuous with very characteristic j'ellow stripe along the dorsum of the body, which is also 

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

 particularly on segments 1, .5, and fi. 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, widens gradually from anterior margin of eighth, and narrows 

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

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



"Three specimens from Atlanta, Ga.; two from St. Louis, Mo., and one from Fortress TNIonroe, 

 Va." (Riley MS.) 



Pupa. — " Similar to that of L. ferruffinea, but somewhat more tapering, and projecting at the 

 til) in two dorsally directed, very strong, short widely separated si)urs. (Anterior half of i>n|>al 

 shell wanting.") (Riley MS.) 



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



Fond phint. — Quercus. (Thaxter and Riley.) 



This is evidently Tepjier's Drynohia tortitosa and Herrich-Schaefter's species, as 1 have 

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

 ■collection.
