and straight to tlio middle of the discal space, where it meets the lower 

 diseal which is thrown off" at right angles to its nervure, and npon this 

 nei"vule the discal fold terminates in a fork". The upper branch of the 

 3rd s. c. is very short and proceeds straight to the costa. 



Costa of the hind wings bent down somewhat at the apex. Outer 

 margin oblique, not very full, bent slightly on the first median interspace. 

 Legs very hairy, fore tibiae very pilose, presenting a flat expansion on 

 the outer side; middle and hind tibife with two long sharp nearly equal 

 spurs. Abdomen long and cylindrical; tip square, hardly tufted. 



In its coloration and style of markings the only species of this genus 

 yet known is gray, with darker longitudinal streaks and slashes. It is 

 more streaked than any member of this subfamily, and from this charac- 

 ter and the resemblance it bears to Xylina in its style of coloration, as well 

 as its elongated wings and general appearance, the generic name has 

 been selected. 



This genus seems to be the connecting link between Coelodasys and 

 allies and Heterocampa, Lochmteus and other closely related genera. 

 It dift'ers from Heterocampa in its narrow wings, straight costa and an- 

 gular hind wings, and in possessing a tuft on the fore wings. Indeed, 

 the short stout palpi and strong pectinations, the very distinctly scaled 

 pronotal pieces and the tufted primaries, together with the densely 

 pilose sternum, will prevent the genus from being confounded with any 

 of its allies. 



Xylinodes virgata nov. sp. 



% . Pale cinereous. Pronotal pieces discolored with ligneous brown. 

 A broad median thoracic dusky line, succeeded on the abdomen by a 

 dark spot. Primaries light ashen with brown scales arranged in streaks, 

 which on the costa proceed obliquely towards the outer margin, ending 

 upon the subcostal nervure. Towards the apex are two distinct brown 

 streaks, which are parallel to the costa; between and below the second 

 streak are two whitish streaks. A dark brown discal dot is placed upon 

 the lower discal nervule, and beyond it is a brown streak. In the 

 middle of the discal space is a light line which passes over the discal 

 dot and continues along the lowest subcostal interspace to near the 

 outer margin. Below the median the wing is slightly tinged with och- 

 reous. Just below the basal portion of the median nervure is a brown 

 streak, and the internal border is mottled and streaked with dark cine-
