A. R. Wilson. — Melanippe tristata ? — I would talie it as 

 a great favour if you would name the accompanying moth. 

 The only moth that it resembles is Melanippe tristata, but it 

 differs from it materially, being much lighter, and the black 

 bands being narrower and more interrupted. I took about 

 eighteen of them in June among junipers ; they were abundant, 

 but the wind was high, and I had great difficulty in catching 

 them. They are all light; in fact I have sent you about the 

 darkest of the lot. 



[Mr, Wilson's Geometra appears to be a light-coloured 

 specimen of Tristata, Linn, (not of HLibner). 1 believe 

 Baron von Nolckeu first pointed out that two species were 

 confounded under the name of Tristata by European ento- 

 mologists. Dr. Staudinger has adopted his views, and the 

 two species stand thus in the second edition of his 'Catalogue 

 of European Lepidoptera : ' —

Edivard Thomsoi. — Food-plant of Gonepteryx R/iamni. 

 — Can you, or any of your readers, tell me any other food- 

 plant for Gonepteryx Rhamni besides the two buckthorns, — 

 Rhamnus catharticus and R. fraugula ? 



[I have said in 'British Butterflies,' p. 147, that the two 

 buckthorns are the only shrubs on which Rhamni is known 

 to feed. I have no later information on the subject; and it 

 will be interesting if another food-plant should be discovered.

 my garden, but could not find that she deposited eggs. —
