IGO Dr. T. A. Chapman on 



Hyeres is 65 ^. No trace of either of these occurs in 

 the ItaHan races. Nor does Milliere record the slightest 

 trace of them (and he was rather keen on variations) 

 amongst over 50 specimens bred from Hyeres fifty years 

 ago. Without subdividing and naming aberrations on the 

 cristana and hastiana system, it may be useful to give 

 names to the principal forms. 



The typical form Hyerana, Mill., would be characterized 

 as having lighter or darker straw-coloured upper wings 

 with black discal spot and little or no black scaling, and 

 the disc of the hind wings more or less fuscous. This 

 would include the whole of the species as known to 

 Milliere and the species as a whole as it exists in Sicily, 

 As aberrations of this we should have Milliere's var. a, 

 hyerana, ab. alpha, Mill., with greater or less spreading of 

 the discal spot; hyerana, ab. nigro-punctata, n. ab., with 

 more or less conspicuous black scaling in dots and spots ; 

 hyerana, ab. ohsolcscens, n. ab., with the discal spot reduced 

 to a scale or two or absent. 



The very pale race at Capri would be hyerana, vax.pallens, 

 n. var., characterized by general lightness of the tint of the 

 upper wings, and especially by the pale hind wings, with 

 no fuscous tintinof. 



This form may occur as an aberration of the type form, 

 and may present as aberrations ab. alpha and ab. ohsolcscens. 



Then we have var. marginata, Wlsm, This is clearly not 

 a mere aberration of the type form, but is trying to establish 

 itself as a distinct race at Hyeres by swamping and 

 ousting the type, which it is very possible it has done at 

 some other locality or period. This has the aberration 

 marginula, n. ab., with the general aspect of a richly or 

 darkly coloured type specimen but possessing the fine red 

 line in the fringe. It may be regarded as an aberration 

 either of hyerana or marginata or as a cross between them. 

 To be an aberration of hyerana, however, its absence from 

 Sicily makes its claims very doubtful. 



The habits of the larva of H. hyerana at Taormina 

 differed remarkably from those of the same species at 

 Hyeres ; so much so, that at first, when the larvae I found 

 were small, I confess I had some doubts as to their being 

 some other species, unicolorana perchance (I may here 

 mention that I found no trace of ww'co/orawa at Taormina). 

 The great point of difference in habit was that instead of 

 being numerous on a plant, almost gregarious as at Hyeres,
