forth the July following. The caterpillars from the eggs of 
this stock are bred about the first week in August. After the 
usual shifting of their skins they become full fed the end of 
September, and change to a chrysalis in a short time. In this 
state they continue through the winter and until the following 
May.”’—Edward Newman. | 
N.C. Tuely.— Food-plants of Gonepteryx Rhamni (Entom. 
viii. 231).—1 see by the October number of the ‘ Entomolo- 
gist’ that Mr. Wilson was at a loss to find the food-plants of 
Gonepteryx Rhamni. In addition to the buckthorns the 
larva will eat the leaves of the apple, pear, and medlar, which 
no doubt could be supplied in any locality without much 
trouble.—Edward A. Fitch; Maldon, Essex. 
G. Haggar.—Setina trrorella.—I once took a number of 
larve of Setina irrorella at Hayling Island, feeding on a 
ground-lichen which grows plentifully amongst the grass just 
outside the tide-mark. They afterwards fed fairly well on the 
gray lichens, which are not uncommon on apple and other 
trees, and I reared a set of moths. I believe this larva is 
exclusively a lichen-feeder.—[Rev.] H. Harpur Crewe; 
Drayton-Beauchamp Rectory, Tring, October 4, 1875. 
Food-plant of Setina irrorella (Entom. viii. 
234).—In reply to Mr. Haggar, I may say that judging from 
the quantity of imagos I have found stretching, and the 
situation where the insect occurs on the rocks—which are 
well clothed with lichens—at Douglas Head, Isle of Man, and 
where, as stated in the ‘ British Moths, “there seems no 
suitable place for tree-lichens to grow” (Mr. Haggar appears 
to have misread the paragraph), I believe we may safely 
infer that the larva does feed on lichens which grow on the 
rocks; at any rate, so far as the above locality is concerned. 
During the past season I bred a quantity of Nudaria mun- 
dana, the larve of which I found feeding on lichens growing 
on stones: by bringing a few pieces of the stone home I had 
no difficulty in rearing the insect. Perhaps Mr. Haggar 
might succeed in a similar way with Setina irrorella.—

plant of Setina irrorella, in the October number of the ‘ Ento-
