Two % . In C. isoinera, the lower inner cell of under wing either 

 coincides with that above it at its apical end or extends beyond it. 

 The antennaa are longer. This is somewhat like Priopliorus pilosicnr- 

 nis, sent me from England by Francis Walker, Esq. 



Euura salicis-nodus. Walsh, % . 



I have received from Mr. Walsh the female, which differs from the 

 male in having the pale inner orbital lines distinct throughout. The

 plates, and the whole of abdomen, above and below, honey-yellow. 

 Each segment of abdomen tipped with black, above aud below, most 

 distinctly upon the tergum. The anal styles are tipped with black. 

 Both % and 9 bred by Mr. Walsh from galls received from New York.
