species, rupicola and arbuti, but says that he has never seen a 

 specimen of the former ; thus indicating the latter as his type. 

 In his Nat. Hist. Lep. Noct. ii. p. 197, he distinctly marks 

 H. arhiiti as type of Heliodes, and omits rupicola from the genus. 

 Dr. Staudinger takes the latter as type of Heliodes, and thus 

 applies Guenee's generic name to a group for which it was not 

 intended, with a type unknown to the author of the genus. 

 Anything more opposed to practical common sense can hardly 

 be imagined.

Re-union between the same Moths. — Mr. J. N. Young's note on this 

 subject (atite, 268) is of especial interest, following, as it does, so closely on 

 a parallel case mentioned by Mr. Eustace R. Bankes (E. M. M. n. s. ii. 

 274), in which the species affected was Ephestia kuhniella, and one exactly 

 similar that came under my own notice in 1889, in which a bred male and 

 female Spilosoma mendica, observed in cop. at 8 a.m. on May 25th, were 

 found in the evening of that day to have separated, and ova to have been 

 deposited, and on the following morning, at the same hour, they were again 

 found paired, more ova ultimately resulting. But the question that these 

 records suggest is whether a second act of pairing is frequent in wild 

 Lepidoptera, and, in fact, necessary for the due fertilisation of the ova con- 

 tained in the female ? It was a saying with many of our older collectors 

 that if you could take "a pair in cop." you were pretty sure of a "fresh 

 female," which would appear to imply that only freshly- emerged females 

 paired. But recent observation induces me to believe that this is by no^ 

 means so, and as an instance I may mention the following : — During a brief 

 stay at Eastbourne in August last'l found Lycana corydon very commonly, 

 and among them a great many pairs in cop. ; in some cases both male and 

 female, and in others one or the other, were, without doubt, quite freshly 

 emerged ; but in a large number it was only too evident that both had been 

 on the wing for a considKrable time, and it is hardly to be supposed that 

 with both sexes flying so commonly either would become worn before finding 

 a mate. — R. Adkin ; Levvisham, November, 1891. 



Abnormal emergence of Demas corylt. — On looking over my 

 breeding-cages yesterday, I was surprised to see in one of them a fine 

 freshly-emerged female of Demas corylL The larva from which it was reared
