ing of the whole insect, depicting a form of wing entirely 
foreign to the bittacids, but similar to that of most Trichop- 
tera. Hagen’s drawing of the wing of one of his speci- 
mens, however, is that of a typical Bittacus and agrees in 
venation and size with the wings of a species in the Harv- 
ard collection. Since none of the bittacids in this collec- 
tion has a short beak or a wing-form like that shown in 
Pictet’s figure, I believe that the four specimens which 
Hagen identified as antiquus were not that species. I also 
believe that Pictet’s type specimen of antiquus is not a 
true bittacid; it may have been a trichopteron, but since 
its identity is very uncertain, I propose that antiquus, 
which now carries the generic name Electrohittacus, be 
considered a nomen duhium. The species which Hagen pre- 
sumably had is described here as fossilis.
