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 Phihalapteryx agitata, — 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 a reply from either of your correspondents, the 

 Rev. J. Greene or Mr. Doubleday. As 1 had taken pen in 

 hand without noticing your special invitation, I venture still 

 to give my opinion and experience. 1st. — 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 

 chn attest to the same fact, having frequently obtained eggs, 

 and hatched larva) from the same, from moths captured at 

 sugar.— [AV^'.] E. H. Eyles ; Enfield, Octoher 6, 1871.
