14 THE ENTOMOLOGIST. 



I have not met with this species myself, and so have not included 

 it in my list. 



It is by no means improbable that other species of Rhopalocera 

 may occur in the Enfield district, as the area I have worked is 

 extremely limited ; in fact, twenty of the species contained in the 

 above list were captured in a single field, about three acres in 

 extent, situate a few hundred yards from the house. Of the other 

 five species, two (F. pnlychloros and P. megcBva) were taken on 

 " The Cedars Estate " itself, and the other three {A. paphia, E. 

 hyperantlies, and T. quercus) in a wood which is distant about 

 one mile.

ADHASTUS FALLENS, Fab., A BRITISH SPECIES. 



By Eev. H. S. Goeham, F.Z.S., &c. 



The species standing in our lists as Adrastiis limhatus, Fab., 

 is not that species according to Riesenwetter, but agrees with 

 Adrastus palleiis, Fab., and this appears to me to be the true 

 determination. All the specimens in my own collection are to be 

 referred to the latter. A. limhatus, F., is, among other points, to 

 be separated from A. pallens by having the tbird joint of the 

 antennge much longer than the second, and the legs more or less 

 infuscate. There is a little confusion in Riesenwetter's diagnosis 

 of ^. Umbatus from the repetition of the word " testae eis," where 

 " infiLScatis " is plainly the word he intended. The antennae in 

 A. limhatus are also infuscate, with the base yellow. In A. pallens 

 they are wholly yellow, at the most faintly infuscate in the apical 

 three or four joints. There is a variety oi A. pallens with the 

 suture infuscate ; this is (according to Herr von Riesenwetter) 

 the Elater limhatus of Paykull and Gyllenhal. The synonymy of 

 our species will therefore stand : —
