species among those who had taken part in the controversy, 

 only three of the writers holding the opposite view, viz. Rev. 

 G. A. Smallwood, and Messrs. R. South and C. G. Barrett. 

 He then critically reviewed the various statements on the 

 subject, and argued that Mr. Smallwood practically gave in 

 all that he had contended for by finally assuming that T. 

 biundularia is a species, and T. crepuscidaria a sub-species, 

 and that Mr. South's remarks (" Entomologist," xix., 

 pp. 269 — 272), were utterly beside the question. 



Referring to Mr. Barrett's rem.arks (" E.M.M." xxxii., 229), 

 Mr. Tutt went on to say that the assumption that because 

 Mrs. Bazett had never seen T. crepnscularia in a certain wood 

 at Reading, therefore it did not occur, was not at all satis- 

 factory, and that as to his statement that the second brood 

 of T. crepuscidaria were " in markings and colour typical 

 southern T. biimdtdaria,'" the series exhibited by Mr. 

 Henderson, Mr. Mera, and himself were a sufficient refutation. 

 He had no hesitation whatever in referring the specimens 

 obtained by the keeper, who gave them to Mrs. Bazett, to T. 

 crepuscidaria, and not to T. hiundtdaria. He considered that 

 Mrs. Bazett had made a grave mistake in recording second 

 brood specimens of T. biundularia. Mr. Tutt then gave a 

 detailed account of Scotch T. creptisctUaria, of which he 

 exhibited some sixty specimens, and said that they more 

 closely resembled the typical German form than any other 

 British specimens. He referred to the evidence offered by 

 Messrs. Porritt, Tugwell, Fenn, and others, who had bred 

 both species, as to their distinctness, and pointed out broad 

 differences in the shape of the wings, &c. He said that 

 colour was no guide, for although, on the whole, T. 

 crepuscidaria, var. abietaria, was darker than T. biundularia, yet 

 some T. crepuscidaria were whiter than any T. biundularia. T. 

 crepuscidaria gave white, ochreous, fuscous, and black (brown) 

 forms ; T. biundularia white, ochreous, and black forms. Yet 

 the specimens were always abundantly distinct, and 

 parallelism of colour variation, he considered, would not 

 unite species. Mr. Tutt then pointed out that dates of 

 appearance were misleading if dates of years like 1888 were 

 compared with those of a year like 1S93. Third broods of 

 T. crepuscularia were then referred to, Mr. Tutt asking 

 members to compare the second broods of the species 

 exhibited by Mr. Mera, Mr. Henderson, and himself with 

 typical T. biundularia, and to say whether they were, as Mr. 

 Barrett had insisted, "obviously T. biundularia.'' The 

 differences, in his opinion, were patent when there was
