4 THE ENTOMOLOGIST S RECORD. 



of the females, and the corresponding differences between the penis- 

 sheaths of the males. 



In a future note I hope to record the results of my attempt, made 

 six years ago, to find reliable rlistinctions between these two species 

 in their larval and pupal stages.

C(£nobia rufa, Hw., ab. fusca, n. ab. 



By EUSTACE R. BANKES, M.A., F.E.S. 



Forewings dark fuscous, somewhat tinged with red. Hindwings 

 dark grey, paler towards the base. The usual black dots on both fore- 

 and hindwings are either visible or traceable. The head, thorax, 

 cilia, etc., are proportionately dark as compared with the type. 



I have taken this interesting aberration, which differs from the 

 type in its remarkably dark colour, very sparingly of recent years in 

 the Isle of Purbeck, Dorset, among some hundreds of Coenohia rufa, 

 which have included examples of ab. pallcscrns, Tutt, and ab. Uneola, 

 Stph., as well as typical specimens and individuals of every inter- 

 mediate shade between these last and the darkest representatives of 

 ab../'»scft. Hitherto I have not come across any females approaching 

 the colour of the form under notice, but it would be rash to assume 

 from this fact that ab. fusca is confined to the male sex, for, in my 

 experience, females are rarely met with, and of them my captures have 

 only numbered eighteen. It may be mentioned, in passing, that all 

 have been taken at dusk or late dusk, and all, wath possibly one or 

 two exceptions, on the wing, and, curiously enough, seven of them 

 were secured on the rather cool and windy evening of August 2nd, 

 1905, when my total bag of C. rufa only included 26 individuals ! 



I have failed to find any published reference to this extreme form, 

 or to obtain any information of its occurrence elsewhere. 



A close acquaintance with L'. rufa, extending over some years, has 

 convinced me that, in the spots in the Isle of Purbeck where I have 

 found the imago most numerous, the larva must feed in the stems of 

 Jtmcus efusua, though this conviction still awaits the confirmation of 

 positive proof. 



Variation of Aglais urticae. 



By (Rev.) G. H. RAYNOR, M.A. 

 Some dozen years or more have now elapsed since my very good 

 friend Mr. W. H. Harwood, of Colchester, drew my attention to the 

 possibilities of this species in the Avay of variation. Since then I have 

 bred it in large numbers every year, and have also had the privilege of 

 seeing all the remarkable varieties reared by Mr. Harwood. After 

 studying the species for so long a period, I realised about a year ago 

 that it was high time to evolve some order out of the chaos, in the 

 way of arranging the specimens I possessed. With a view to 

 accomplishing this, I did what is absolutely necessary for the successful 

 study of any species, i.e., J got a thorough mental grasp of all the
