are not thickened towards the apex ; by its finer punctuation through- 

 out ; by the pronounced broad black band on the elytra ; and by the 

 fact that the marginal bristles of the elytra are long and stout, as in 

 T. chrifsomelinus, and not short and fine, as in T. solntiis. Variation 

 IN LuPERiNA GUENEEi.— Mr. Hy. J. Tumer exhibited several very 

 interesting forms of the little known species Lupcrina (jueneei, sent to 

 him for examination by Mr. Murray of St. Anne's-on-Sea, Lancashire, 

 including two new aberrations, riz. (i) ab. murrayi (n. ab.), named 

 after its captor, which is quite typical /.. tpteneei in texture, shade of 

 colour, and in markings, with this very marked difterence, that the sub- 

 marginal area, between the dark marginal lunules and the submargmal 

 line, is much paler than any other portion of the wing, throwing out by 

 contrast these dark lunules very conspicuously. In the worn specimen 

 this feature was even more apparent than in the perfectly fresh 

 example. In var. ha.vteri this same area instead of being lighter or 

 uniform with, is distinguishably darker than the general wing colour, 

 (ii.) ab. fusca (n. ab.), of which three specimens were exhibited, which 

 are undoubted L. (jueneei in all their characters but depth of colour ; 

 these are believed to be the first melanic specimens which have been 

 so far obtained. All the markings are much intensified, the ground 

 colour is much darker than in typical examples, very dark grey with, 

 in a good light, faint flushes of a ferrugmous tint. The contrast 

 between ground colour and markings is very much stronger than in 

 any of the other forms. In the worn specimen of this form this 

 contrast appears almost equally strong. There is no trace of the 

 " ochreous tinge" of the type nor of the typical " pale grey ground 

 colour." Varieties of Coleoptera. — Mr. Champion exhibited on 

 behalf of Mr. J. H. Keys the black variety of Athous Iiaeuiorrhoidolis, 

 F., from Dartmoor, recorded by the latter in the tbit. Mo. Ma;/, xlvi., 

 p. 262 ; and also a red variety of the S' of Aijabiis bipustiilatus, L., 

 from the same locality. Polygonia c-album, var. hutchinsoni in the 

 2nd brood. — The Rev. A. T. Stiff, who was present as a visitor, was 

 introduced by Dr. Chapman, and exhibited some 2nd-brood specimens 

 of the var. hutchinsoni of Pohjjonia c-albuin. He remarked that they 

 were bred from Wye Valley larvfe, received from Mr. L. W. Newman, 

 F.E.S., September 24th, 1910. The vars., including three inter- 

 mediates, emerged on October 16th, 19th (three), 20th, 21st (two), 

 22nd, 23rd and 26th, 1910. It is believed that there is no record of var. 

 ItiitcJtinxuni having been bred in the 3nd brood of c-albuiu. Mr. 

 Newman writes : " I have bred thousands of c-albuui of the second 

 brood in various years, and never one hutc/iinsoni, and I have never 

 heard of any one else doing so." Mr. Rowland-Brown and the 

 Chairman both observed that on the continent they had taken hyber- 

 nated specimens of P. c-albuui of the /lutchinsoni form. Papers. — Dr. 

 O. M. Renter communicated a paper entitled " Bryocorina nonnulla 

 Aethiopica descripta ab. 0. M. Renter et B. Poppius." — Col. Manders 

 sent a paper, which was read by Com. Walker, entitled " A factor in 

 the production of mutual resemblance in allied species of butterflies," 

 which was the sul)ject of some criticism from Dr. Chapman and Mr. 

 G. A. K. Marshall. Mr. Merrifield added a few observations with 

 regard to the comparative immunity of Pierine butterflies from the 

 attack of birds. Vote of Condolence. — A vote of condolence with 

 the family of the late Mr. J. W. Tutt was moved from the Chair, 

 all the Fellows present signifying approval by rising.
