PtHOPALIA. 



I know nothing about the value of these genera, as I have not even 

 seen the description of JErcmomydas nor have I seen a specimen of Feris- 

 socerus. I do not beheve that the presence of a recurrent veinlet near the 

 base of the upper branch of the cubital fork is of generic value, althouo-h 

 it has been used by Gerstaecker to separate Leptomydas from Rhopalia. 



Only one species is satisfactorily recorded and described from Europe 

 {Leptomydas lusitanicus from Portugal), but A. Costa described M. 

 sardous from Sardinia and I possess a specimen of Leptomydas from Corsica 

 which has a few distinct spines under the hind femora ; Dufour described 

 L. Iusita7iicus as occurring in Corsica, but stated that that species has 

 no spines beneath the hind femora. 3f. rvfipcs Westwood is a doubtful 

 species which was recorded with doubt from Sicily.
