rated punctures, clothed with long, erect, white pubescence; last 

 tergite with a fringe of long, white pubescence at the base, other- 

 wise bare, finely longitudinally rugose; first sternite with a distinct

 fringe of pale hairs slightly interrupted medially with a few dark 

 hairs ; sternites 3-6 indistinctly punctate, sparsely clothed with black 

 pubescence, the apical fringes black except for a few white hairs 

 laterally; apical sternite indistinctly punctate, clothed with sparse 

 black pubescence.

Paratype. — Male, Andrade, California, Colorado Sand Desert,

This is possibly the male of noctuma. It was collected at light 

 at 11 o'clock at night the same as the latter. As there is no other 

 evidence for uniting them as male and female of the same species 

 other than that they were collected at the same time and place, it 

 seems best to describe them as two species. D. subhyalina is quite 

 remarkable on account of the abnormally large eyes and ocelli. 

 Large ocelli are the rule in the genus Photopds^ but this species has 

 none of the other characters of that genus and is obviously a Dasy- 

 iivutilla. It may also be distinguished by the subhyaline wings which 

 is unusual in males of this genus.
