SCIENTIFIC NOTES. 85 



and on the 14th Sati/nis riilici was taken opposite the depressing 

 bathing-place of the Eaux Chaudes. A hot tramp to St. Benoit along 

 the right bank of the Bleone resulted in several male F. iiit'leai/er, one 

 S. fiiiia, and my first and last ^'. brisei>i. The next few days saw 

 nothing fresh to report. I have often noticed that a single specimen 

 appears, as the advanced guard of a species, and not another is seen 

 for a week or more, when the main body come on. I had come to 

 Digne especially to get the Satyrids, and a few other species, and I had 

 taken them all, with L. celtis, L. roboris, and xY. acaciae besides. My 

 last note, written on the day of our arrival home, reads curiously in 

 the light of recent events: "20th, Digne to Grenoble; 21st, Grenoble 

 to Paris ; 22nd, Paris to London ; 28rd, Austrian ultimatum to 

 Servia. Where shall I collect in 1915 '? " 



.^^CIENTIFIC NOTES AND OBSERVATIONS. 



Agriades cokidon ab. roystonensis, Pickett. — In Tlie F'.ntinitohxiisi's 

 Record, vol. xxvi., p. 275, appears an article by Mr. C. P. Pickett, in 

 which an asy'mmetrical form of A. coridon is described under the 

 varietal name "roystonensis." It will probably obviate considerable 

 confusion in the future if Mr. Pickett will more precisely indicate 

 which forms are included under this name. In Mr. Pickett's first 

 paper [Ent. i^^-c, xxvi., p. 59) he refers to the exhibition of a specimen 

 of A. coridon by Mr. Newman at the South London Entomological 

 and Natural History Society, "a 2 specimen with asymmetrical 

 wings, the smaller pair dusted with blue" {ibid, p. 25), and subsequently 

 refers to the capture by himself and others of other specimens. These, 

 he says, have " one side more or less dusted strongly with blue," and 

 as they are " similar " to Mr. Newman's specimen one may assume 

 that all have one pair of wings dusted with blue, and this pair smaller 

 than the other. On page 60 Mr. Pickett says, "I . . . . can 

 now total 48 females of this form, and have also seen a lovely asym- 

 metrical male.'' 



There the matter remained until the publication of Dr. Cockayne's 

 masterly examination of these forms in the Kiit. luc., xxvi., 221, in 

 which, before describing specimens in detail, he says, " Last year . 

 . . a considerable number of specimens were taken, whic-h had the 

 wings on one side smaller than the other and a variable amount of 

 blue scaling on the small side. Mr. Pickett recorded 43 examples in 

 his paper in the Ent. Her., xxvi., p. 59, and doubtless more had been 

 captured. The form has recived the name ab. inequalis." 



In my own notes, p. 272, I also referred to these forms as " ab. 

 ineqnalis, Tutt," as I had previously done in describing Mr. Pickett's 

 exhibit at the London Natural History Society (p. 212). Mr. Pickett 

 corrected me (p. 260) though, as his name was not then published, 

 and the specimens appear to come within Mr. Tutt's description {Nat. 

 Hist. Brit. Butts., iv., 80, I do not think I was in error. In any case, 

 if I sinned, I feel that I sinned in good company. 



Mr. Pickett says, in his recent paper, that Tutt " surely meant the 

 usual form where the blue was either streaked or splashed on one side 

 more than the other." This may be so, as no specimen similar to any 

 of the "roystonensis" is mentioned by Tutt, and one is therefore almost
