is very long, extending about a quarter of an inch below the end of 

 the pupa. It remains about twenty-one to twenty-eight days in this 

 state. There is no doubt this species is very badly attacked by 

 ichneumons, and also by dipterous flies, in all its stages, including 

 the ovum. It is also eaten, whenever caught outside its house, by 

 ants, mantis, cockroaches, &c., more particularly in the first two 

 stages. The butterfly is fairly common, and has been fully described 

 by Mr. Eoland Trimen.— Geo. F. Leigh, F.E.S. ; Durban, Natal,

Entomological Society of London. — Wednesday, February 1st, 

 1911.— Mr. G. T. Bethune-Baker, F.Z.S., in the chair.— It was 

 announced that the Council had nominated the Eev. F. D. Morice, 

 M.A., as President for the current year. — Mr. W. J. Kaye exhibited 

 several Heliconii from Eastern Ecuador, including the forms H. ruhri- 

 l)icta, adonidcs, and feyeri with streaked hind wings. He observed 

 that it seemed now to be possible and even likely that H. melpomene 

 aglaope would eventually be proved to be linked with H. plesseni 

 through these newly discovered forms, and that this species would 

 then have to be sunk as a subspecies of H. melpomene. Similarly, 

 H. notabilis through ilia and feyeri was probably only a subspecies 

 of H. erato, though the material was insufficient at present to form 

 a conclusion. — Dr. Nicholson exhibited a new species of Tacliyporus 

 which he has named fasciatus. There were two specimens taken at 

 Wicken Fen from under sedge refuse, the one in April, the other in 

 August, 1910. This species is intermediate between T. solutus, Er., 

 and T. clirysomelinus, L. It differs from the former in the shape of 

 tlie antennae, which are of the same length, but are not thickened 

 towards the apex ; by its finer puncturation throughout ; by the pro- 

 nounced broad black band on the elytra ; and by the fact that the 

 marginal bristles of the elytra are long and stout, as in T. chrysome- 

 linus, and not short and fine, as in T. solutus. — ^Mr. H. J. Turner 

 cxliibited several very interesting forms of Luperina guencei, includ- 

 ing two new aberrations: — (i) ab. murrayi (n. ab.), which is quite 

 tj^pical L. gueiieei in texture, shade of colour, and in markings, with 

 this very marked difference, that the submarginal area between tlie 

 dark marginal lunules and the sulmiarginal line is much paler than 

 any other portion of the wing, throwing out by contrast these dai'k 

 lunules very conspicuously ; (ii) ab. fusca (n. ab.), of which the three 

 specimens exhibited are undoubted L. cjueneei 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 

 ferruginous tint. The contrast ])et\veen ground colour and markings 

 is very much stronger than in any of the other forms. — Mr. Cliampion 

 exhibited on behalf of Mr. J. H. Keys the black variety of Athous
