 Oxyptilus delairaricus, Zcll. Verb. z.-b. Ges. Wien, sxiii. p. 318.

 less conspicuous than in 0. pilosellw. An indi- 

 stinct pale spot lies on the dorsal margin one 

 fourth from the base. There is a white spot

 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

 the upper one nearly straight, the lower one
