426 THE ENTOMOLOGIST. 
I am much interested in this subject, and shall greatly 
value farther details. Please, therefore, inform the readers of 
the ‘ Entomologist’ when the moths come out. 
Thomas Parmiter.—I regret my inability to make out the 
name of the moth you have so minutely described. Could 
you trust it to some safe hand when you are sending to 
London? 
Larva of Phibalapteryx aquata.—M. Berce has dis- 
covered, in the Forest of Fontainebleau, the previously 
unknown larva of this very interesting geometer. He has 
succeeded in rearing it, and has thus obtained specimens in 
the highest state of perfection. It feeds on Clematis Vitalba, 
and not on Juniperus communis, as was supposed: it is 
found in May and July, and may be looked for in England. 
Eyes of Insects.—Dr. Pouchet, residing at No. 1, rue 
Hautefeuille, Paris, is desirous of comparing the highly- 
‘developed eyes of certain insects with those of insects having 
simpler eyes, while they are merely in a rudimentary state ; 
and he will be obliged for living specimens of blind insects, 
remitted by post in damp moss, together with information 
respecting the places they inhabit. 
Moths and Sugar.—Under the heading of “moths and 
sugar” your correspondent asks certain questions, to which 
you invite areply from either of your correspondents, the 
Rev. J. Greene or Mr. Doubleday. As I had taken pen in 
hand without noticing your special invitation, I venture still 
to give my opinion and experience. I1st.—As to the greater 
frequency of males than females at sugar. Allow for the 
generally somewhat later date of emergence of the latter sex, 
and I am of opinion that of many species there will not be 
much difference in the number of captures of the two sexes. 
The greater sluggishness or (to be more polite) inactivity, 
and the domestic duties of the females of some species, will 
account for their discrepancy in numbers at those convivial 
gatherings, at which the males assemble in such force. The 
letter of Mr. Doubleday to yourself, contained in the same 
number, indirectly answers the latter question as to eggs. I 
can attest to the same fact, having frequently obtained eggs, 
and hatched larve from the same, from moths captured at 
sugar.—[Rev.] H. H. Eyles ; Enfield, October 6, 1871. 
Caterpillar of Goat Moth.—A boy has just brought me a
