tion fed freely on the leaves, mainly»eating them from the edge 

 inwards, but now and then they devoured holes in the leaves. 

 The adult is shiny black, with paler incisions on the venter; the 

 legs pale, and also the base of the wings. 



The insects were very kindly identified for me by the Eev. 

 F. D. Morice, who writes me that L. mcestus of Zaddach is the 

 same as L. brevicornis, Th. (1862) (non Cameron). 



NOTES AND OBSERVATIONS. 



Some Aberrations of British Lepidoptera: Euchloe carda- 

 mines. — Thanks to the photograph on page 28, antea, I am able to 

 identify the albinistic aberration of cardamines, taken at Cock Clarks, 

 Essex, as ab. lasthenia, Milliere (Ann. Soc. Linn. Lyon, 1860, 3me 

 livr. pi. 10, figs. 1 and 2). Milliere figures a male. Mr. L. C. Hocking 

 also figures a male. I have in my collection a female lasthenia 

 taken in the environs of Sedan, Department of Ardennes. The 

 example figured by Milliere was captured at Digne, Basses-Alpes, 

 by Donzel. I think it may be interesting to publish this information 

 in the ' Entomologist.' — -Charles Oberthur, Rennes, Ille-et-Vilaine, 

 France, February 5th, 1913. 



The form figured by Mr. Hocking, and identified by M. Oberthiir 

 as ab. lasthenia, Milliere, is included in the account of E. cardamines 

 in Tutt's ' British Butterflies,' 1896, p. 245. Milliere's description is 

 as follows : " Larger than the type. The front wings and the hind 

 wings appear to be more elongate, and less rounded than those of the 

 type. The insect, in fact, seems to me to present an entirely different 

 facies to that of the several male and female cardamines under 

 my eyes ; so much so that this butterfly might well be a distinct 

 species. . . . The apical orange blotch, which is a little less vivid 

 than in ordinary cardamines, occupies the same position, but the 

 border of the apex is entirely without black ; also the discoidal 

 spot. In lieu of the characteristic spot and the black border 

 broken with white, absolutely nothing is visible except the milky 

 ground colour. The basal area of all four wings is quite white, 

 and the under side markings, which in male cardamines always 

 show through more or less above, are indistinguishable. The hind 

 wings are also remarkable. The green under side spots of the type 

 are replaced by spots of a very faint greenish yellow, arranged almost 

 in the same way as in ordinary cardamines. Antennae white. The 

 plumules of the frontal tuft (toupet) pure white. Abdomen rather 

 slender and long, white, as well as the legs." Milliere, in fact, seems 

 to have thought that, if not a distinct species, lasthenia might prove 

 to be a hybrid with sinapis. 



Further Notes on Hesperiid Classification. — In the paper by 

 me, concluded at page 28, I did not make it sufficiently clear that, of 

 the Swiss authorities cited, I am indebted to Dr. J. L. Reverdin alone 

 for the many and minute distinguishing characters of the Hesperiids 

 under review. Also that Plate iii. was originally designed and
