This species is the type of the genus Erruca ; Lcemocharis can 

 scarcely be said to have a type ; I therefore prefer to consider L. 

 stidta and allies as representing that genus.

Although I do not intend to incorporate in the present paper 

 all the new Zygsenidse described by Felder, but only those genera 

 of which we possess representatives in the collection of the British 

 Museum, I have been tempted to quote the above as being a 

 transition from Erruca to Myrmecopsis.

The genus Myrtnecopsis has been confounded by Dr. Herrich- 

 Bchaffev vfith FsetcdospJiex ; it was not, however, founded upon 

 Hiibner's type (which was P. zethus); it diifers entirely in neu- 

 vation from that insect and its allies, and must therefore be re- 

 tained as distinct with Newman's designation. Herrich-Schaffer 

 had the acumen to see how entirely different the two types were ; 

 but he took the type of Pseudosphex out of its genus and consti- 

 tuted for it his genus Abrochia ; he appears to me, however, to
