Enodis, L. noji Kl., = atrata, Kl. ; nigripes, Br. and Zad. — The 

 wings in this species are lighter coloured than in violacea, the dark 

 violaceous tint, as a rule, only extending to the middle, while the 

 hinder pair want it entirely. Easily known from it otherwise by the 

 form of the 8rd transverse cubital nervure ; longer 3rd cubital cellule ; 

 by the recurrent nervure in the hind-wings being received nearer the 

 middle of the cellule, and by the accessory nervure being appendicu- 

 lated further from the middle. If anything, the head is more strongly 

 dilated behind the eyes, and the front is more projecting. 



Berberidis. — The peculiar structure of the sheath of the ovi- 

 positor in the ? renders that sex easily recognisable, but the ^ is not 

 at all readily separated from the same sex in enodis. The antennae 

 apparently are a little longer ; the antennal tubercle is deeper, so that 

 the carinae are sharper, the 3rd cubital cellule is longer, the recurrent 

 nervure in hind-wings is received nearer the end of the cellule ; 

 usually, the wings are darker. I am not quite satisfied that the 

 specimen (a (^) representing herheridis in Stephens' collection is 

 actually that species ; so that further evidence of the British nativity 

 is very desirable. 



G-RACiLicORNis, $ , = cyanella, Kl., = pilicornis, Leach. — This 

 species has a more slender body than any of the other species of the 

 same coloration, and is easily known from them by the head not being 

 dilated behind the eyes, by the more oblique 3rd transverse cubital 

 nervure, by the 3rd cellule being more dilated on upper-side, and by 

 the longer and more slender antennae. 



EusciPES, = violacea, Klug, non Fab. — Compared with ciliaris, 

 fuscipes is a larger and broader insect ; its head is, if anything, more 

 swollen, the incision in the clypeus is deeper, and otherwise it is
