ADELA. 



A. biviella Zell. 



I have received both sexes of this species from Prof. Fernald, of Orono, 

 Maine. It is a prettier species than A. bella Cham., with the fasciae much 

 more distinct. Zeller describes only the $ . It has the head and palpi 

 dark brown with a very faint purplish tinge; the antennas with annulations 

 of dark purple and silvery white ; the body and legs dark purple, the legs 

 annulate with white ; hind wings pale purplish with darker ciliae ; thorax 

 and fore wings rich deep purple, appearing in some lights to be thickly 

 dusted with brightly scintillating golden scales ; behind the middle of the 

 fore wings is a straight white fascia widest on the dorsal margin, dark 

 margined before, and more faintly so on the costa behind ; before the 

 apex is another fascia which does not quite reach the dorsal margin and 

 which is dark margined before. Zeller represents this fascia as having a 

 sigmoid outline, but in one of my specimens it is perfectly straight and in 

 the other scarcely perceptibly sigmoid. Al. ex. 7 lines. 



The % (a single specimen), now first described, differs only in having 

 the hairs of the head straw yellow, those of the palpi whitish, and the 

 second fascia reduced to a very short white costal streak. 



The antennae are simple in both sexes. 



A. bella Cham. 



The fasciae in this species are as stated in the original description in 

 the apical part of the wing, only visible in certain lights and are very 

 indistinct even then ; perhaps it would be more correct not to describe 

 them as fasciae, but to say that the apical part of the wings is somewhat 

 suffused or overlaid with golden, except three or four narrow indistinct 

 transverse lines, which are of the general hue. In the % the basal half 

 of the antennae are densely clothed with long scales.

In my judgment the characters of this and similar species are sufficient 

 to distinguish them generically from Adela as represented by such species
