This species was described in my 

 Synopsis from the rudiment of a female

 thus the paler colors are explained. I 

 have seen 15 specimens male and female.

A pair caught in copula at San Diego, 

 California by Mr. Crotch induced me to 

 separate them as species. The size and 

 external appearance is similar to 

 D. niadida. The wings are hyaline, 

 with the anterior margin to the mediana 

 and a small space at the base of the hind 

 wings flavescent. The male is similar 

 to D. madida but the superior append- 

 ages have about a dozen small teeth on 

 a line beneath the apical half. The 

 female has on each side of the thorax 

 an oblique pale band, better defined and 

 broader near the legs ; on each side 

 along the abdomen a black band is 

 indicated and is more developed at tlie 

 apex of the segments ; the dorsal median
