take the insect for something that is otherwise utterly unlike 

 it, and such a hesitation would usually cost a bird the insect. 

 In this way incipient mimics should stand a better chance in 

 forest than in open country and be more likely to survive 

 beyond the incipient stages. I had previously applied the 



observation iu thinking out the value of merely incipient 

 likenesses, but had not thought of its bearing on the 'forest 

 versus veld ' problem when I replied to your question." 



EURTTBLA BIARBAS, DrUBT, AM' E. DRYOPB, CRAMER. — Pro- 

 feSSOI POULTON drew attention to a Letter he had received 

 nearly two years ago From Mr. Q. V. Leigh, describing the 

 Inc. 'ding of E. dryope and drawing the inference that the 

 species was distinct from hiarbat, Mr. Leigh had thus been 

 led by his own observations to revise his earlier conclusions 

 on the subject (Proc. Ent. Soc, 1909. p. xxxv). The letter, 

 dated Nov. 26th, 1910, was written from Durban: — 



"1 have to report that, breeding Eurytela dryope from a 

 wild female il cannot give the form <>f the male), I reared 

 22 offspring, all of which were t/r//i>/>r. Apparently, therefore, 

 the two species /■' . hiarbas and E. dryope are different. Mr. 

 A. D. Millar has a captured specimen, intermediate hetween 

 these two butterflies, and such a form may, I think, be the 

 result of a pairing between ilnjo/ie and hiarbas." 



M i LLBRIAH MIMICRY BETWEEN A.UBTRALIAN Bebs. — Pro- 

 fessor Poultom exhibited on behalf of Dr. R. C. L. Perkins 

 a male of Prosopu nvbilosa, Ckll., (Prosopidae), and of a 

 species of HctfictuB {Amir captured by him in the Cairns 



district of North Queensland (duly 1904). Dr. Perkins had 

 pointed out to the speaker the extremely interesting manner 

 in which the resemblance had been brought about, the hard 

 glistening yellow mark on the black scutellum and post- 

 scutellum of the Prosopw, and that on its lateral prothoracic 

 tubercles being mimicked by a yellow pubescence occupying 

 the same positions in the I/xliclus. The latter, having 

 departed from the general appearance of its group, was clearly 

 a mimic of the Prosopis, which bore a pattern also found in 

 many allied species. The males and females of both model 

 and mimic were alike, so that the resemblance would be equally
