88 MEMOIKS OF THE NATIONAL ACADEMY OF SC1E^'CES. 



Abdoiueii cylindrical, sometimes (llehrocampa pulvetea) with a row of dorsal tufts, besides- 

 the oue often present at the base on the first abdominal segment. 



The Notodontidte are associateil with theCeratocauipida', Saturniida', and Jlciuiieucida', both 

 as regards their larval and adult characters. In the moths the. head characters are soinewliat like 

 those of tlie ISaturiiians, tlie clypeus being larj;e and lonj;er than wide, while there are but three 

 branches of the cubital vein in either pair of wings. 



Lufval rharactvrs. — The body is noctuiform, and either smooth and unarmed, or with simple 

 subdorsal lines, or gaily banded and spotted, and armed either with double or simple tubercles, 

 situated either on the eighth" abdominal segment alone or ou other abdominal segments. These 

 tubercles may be double at the end and nutant, or the single one on the eighth abdominal segnuMit 

 may bear a horn and the larva become si)hinx-like. Often the body is hairy and banded, but not 

 usually (except in Datana) both hairy and banded. The eggs low, hemispherical, usually reticulated. 



The pupa obtected, with no vestigial characters; either unarmed or with a well-develoi)ed 

 crenuister. It is either subterranean or more usually protected by a thin, rarely dense, sdkeu 

 cocoon. 



There are seven well-marked groups of the family which may be regarded as of the rank of 

 subfamilies. The most generalized of these groups ajjpear to be the Pyganina-, the Gluphisime 

 seeming to be a side branch, which has undergone reduction and modilicatiou in each stage.

Subfamily I.— Glupiiisin.e. 



Motli. — Head small, not prominent, broad in front; eyes hairy; anteumt shorter than usual, 

 with long pectinations extending to the tips. Palpi small, feeble, slender, not reaching the front. 

 Thorax either smooth or well crested. 



Fore wings shorter and broader than usual; apex of hind wings moderately produced. No- 

 subcostal cell; the first subcostal venule of the hind wings varying much in length, usually very 

 short. Legs densely scaled, the scales spreading out on each side. Abdomen short, tapering in 

 S rapidly to the end. 



The species are ash-gray, varying in being whiter or darker iu hue. But a single genus yet 

 known.
