NOTES AND OBSERVATIONS. 319 



month of June. But here I pause, because there is one circumstance which 

 detracts seriously from the value of this gentleman's testimony, and which 

 makes me hesitate before accepting him as an absolutely trustworthy guide. 

 He is — to put it mildly — slightly inaccurate in his authorities. He states, 

 for instance, that "Lang, in bis ' Pthopalocera Europse ' (of which there is 

 only one edition), gives Erebia manto, Melmiargla ines, Thais rumina, 

 T. polyxena, &c., as being found in Corsica." It will scarcely be credited, 

 but Lang does not mention Corsica as a locality in connection with any one 

 of the four insects named. He states, again, that Mr. W. F. Kirby, iu his 

 ' Manual of European Butterflies ' (only one edition), names Corsica for 

 Voritis apolUnus, Thais cerisyi, Syrichthus therapne, Hesperia nostrodamus, 

 Erebia melas, Ccenonympha corinna, &c. This statement is equally inac- 

 curate, as far as T. cerisyi and E. melas are concerned ; S. sao var. therapne 

 and (7. corinna are included in the list of my own captures. Mr. Kirby 's 

 authority for D. apollinus is Ochsenheimer, who puts it under the head of 

 Sardinia, which country Mr. Kirby, for the sake of convenience, includes 

 with Corsica. Mr. Coleby says: — "I have found two specimens of E. 

 meJas, but of these two I will not be certain "; as though one should say — 

 " here is a peach for you, but perhaps it is only a gooseberry." His Thais 

 rumina was not only " a battered specimen," but it was also " in very bad 

 condition." as indeed battered specimens are wont to be. There is a 

 downright honesty about these two avowals which commands my utmost 

 respect. Is Mr. Coleby sure that he took Lyccena bcetica in Corsica? 

 because Kirby gives L. telicanus, but not bcetica; and I took two undoubted 

 specimens of the former. Pieris chloridice — a South Russian July insect — 

 is not a very likely species to be taken in Corsica in March. If Mr. Coleby 

 can establish this, it will be an interesting fact. As to "over eighty 

 different sorts," I confess I am sceptical, even when such vars. as aristeus 

 of Satyrus seinele, tigelius of Pararge megara, and therapne of 8. sao, are 

 thrown in as "sorts." At the same time, I am free to allow that my own 

 estimate was under the mark ; but then it did not pretend to be more than 

 a guess, and I was not fortunate enough to have Mr. Kirby 's excellent little 

 ' Manual ' at hand to refer to. Since my return, I have looked up the two 

 doubtful Lycmias, mentioned in my paper. I have seen the coloured figure 

 of Boisduval's L. argus var. caUiopis, and it does not at all agree with the 

 Blue that was so common at Tattone, which seems more likely to be the 

 L. agon var. Corsica of Bellier de la Chavignerie, whose description exactly 

 fits it ; and what we took for a peculiar form of the female of L. icarus, is 

 probably the L. astrarche var. astiva, or southern summer form, of 

 Staudinger. — R. S. Standen ; 67, Earl's Court Square, S.W. 



BOAltMIA EEPANDATA PARTIALLY DoUBLE-BROODED. — At the end of 



May last some ova of Boarmia repandata were sent to me from the South 

 of Ireland. They began to hatch on 3rd of June, and for about a month 

 the larvae from them fed up without showing any material difference in 

 relative size. Early in July some few of them began to exhibit a disposition 

 to grow much faster than the others, and on 22nd two were preparing to 

 pupate. At this time about one-half of the brood had developed this 

 tendency of feeding up rapidly, and these all pupated about the middle of 

 August, the moths from them emerging between the 10th of that month 

 and 17th September. The other half of the brood showed no increase in 

 size, and are now hybernating in, to all appearances, the same condition as 

 they were in at the end of July. Mr. McArthur informs me that larvae
