238 THE ENTOMOLOGIST. 



slightest cave in revising would have obviated, unless indeed 

 Monks Wood has power of locomotion to rival the famed 

 Wood of Dunsinane. 



In Mr. Stainton's ' Manual ' one would certainly like to 

 have found the descriptions of the various larvae given from 

 his own personal experience, or, failing this, from some 

 English entomologist's observations, who could describe the 

 larvae found in England, so that there should be no doubt as 

 to the identity of the specimens. 



I find that out of the sixty-five butterflies described by 

 him as British, fifty-two of the descriptions of the larvae are 

 compiled from other writers, five are undescribed, leaving 

 eight only that may presumably have been described from 

 Mr. Stainton's own observations. 



The following table will show this more forcibly: — 

 Twenty-six from Duponchel — C. Edusa, A. Cardamines, A. 

 Galathea, H. Semele, H. Janira, C. Pamphilus, L. Sibylla, 

 A. Iris, C. Cardui, G. C-Albnm, A. Adippe, A. Aglaia, A. 

 Selene, A. Euphrosyne, M. Ciuxia, M. Athalia, M. Artemis, 

 N. Lucina, T. Pruni, T. W-Album, T. Quercus, P. Alsus, P. 

 Alexis, T. Tages, S. Paniscus, P. Comma ; nine from Freyer 

 — C. Hyale, D. Daplidice, A. Paphia, C. Phlaeas, C. Dispar, 

 C. Chryseis, P. Cory don, P. Adonis, P. iEgon ; five from 

 Sepp — L. iEgeria, H. Tithonus, H. Hyperanthus, V. Poly- 

 chloros, A. Lathonia ; three from Boisduval — A. Crataegi, P. 

 Napi, L. Sinapis ; two from H. Doubleday — T. Betulae, T. 

 Alveolus; two from Ochsenheimer — T. Rubi, P. Argiolus; 

 one from Westwood — P. Agestis ; one from Logan — P. Ar- 

 taxerxes; one from Hiibner — V. Antiopa; one from Duncan 

 — E. Blandina ; one from Zeller — P. Sylvanus ; (descrip- 

 tions upon such authorities as Doubleday and Westwood are 

 satisfactory, and the source from which they come proves 

 their reliability). Eight descriptions probably original — P. 

 Machaon, G. Rhamni, P. Brassicae, P. Rapae, L. Megaera, V. 

 Atalanta, V. lo, V. Urticae. Five larvae undescribed — E. 

 Cassiope, C. Davus, P. Acis, P. Avion, P. Actaeon. 



But to turn to individual examples, and take, for instance, 

 the larvae of Atalanta : Mr. Stainton tells us they are soli- 

 tary, differing in this respect from the larvae of our other spe- 

 cies of Vanessa. My experience is quite at variance with this 

 statement. Only during this last summer I found seventeen larvae
