Oxyptilus delawaricus. 



(PLATE II. FIG. 7.) 

 Oxyptilus delawaricus, Zell. Verb. z.-b. Ges. Wien, xxiii. p. 318. 



Head light reddish brown; palpi projecting about 

 the length of the head beyond it, acuminate, 

 light reddish brown, whiter beneath and at the 

 tips ; antennae fuscous, dotted with white on 

 their uppersides. 



Fore wings light reddish brown, paler than in 0. eri- 

 cetorum and 0. pilosellce ; but not so light as in 

 0. periscelidactylus. A few whitish scales are 

 scattered along the costa, which is also slightly 

 shaded with fuscous beyond the middle. There 

 is a faintly indicated whitish antemedian spot, 

 less conspicuous than in 0. piloselloe. An indi- 

 stinct pale spot lies on the dorsal margin one 

 fourth from the base. There is a white spot 

 at the base of the fissure, not preceded by a 

 dark shade as in our English examples of 0. pilo- 

 sellce, but somewhat extended upwards directly 

 towards the costa, and partly connected by a 

 line of white scales in the cilia within the cleft 

 to the first of two pairs of whitish bands which 

 cross the lobes : the first pair, before the middle 

 of the lobes, point obliquely outwards in oppo- 

 site directions, the lower one being somewhat 

 interrupted and less conspicuous than the upper ; 

 the second pair beyond the middle are narrower, 

 the upper one nearly straight, the lower one
