forni, the var. huxteri, and two new and very distinct forms, one of them with a 

 very pale, ahnost white, sub-marginal band, which he was namino' var. murrayi, 

 and the other several very dark melanic specimens which ho was naming var. 

 fusca. Both worn and almost bred conditioned specimens were shown. Mr. 

 Newman, autumn bred specimens of var. hutchinsoni, of Polygonia c-album 

 they were from the same 9 as the yellow forms. — Ht. J. Turner, Hon.

Entomological Society of London : Wednesday, Fehruary 1st, 1911. — 

 Mr. G. T. Bethune-Baker, F.Z.S., in the Chair. 



It was announced that the Council had nominated the Rev. F. D. Morice, 

 M.A., as President for the current year. 



Mr. W. J. Kaye exhibited several Heliconii from Eastern Ecuador, inclu- 

 ding the forms H. ruhripicta, adonides, and feyeri with streaked hind-wing. 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 throxigh these 

 newly discovered forms, and that this species would then have to be sunk as a 

 sub-species of H. melpomene. Similarly, H. notabilis through ilia and feyeri 

 was probably only a sub-species of H. erato, though the material was insufficient 

 at present to form a conclusion. Dr. Nicholson exhibited and described a new 

 species of Tachyporus which he has named fasciatus. There were two speci- 

 mens taken at Wicken Fen from under sedge-refuse, in April and August, 1910. 

 This species is intermediate between T. solutus, Er., and T. chrysomelinus, L. 

 It differs from the former in the shape of the antennae, which are of the same 

 length, but are not thickened towards the apex ; by its finer punctuation 

 throughout ; 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. chryso- 

 melinus, and not short and fine, as in T. solutus. Mr. H. J. Tiu-ner, several very 

 interesting forms of Luperina gueneei, inckiding two new aberrations: (i), ab. 

 murroAji (n. ab.) which is quite typical L. gueneei in texture, shade of colour, 

 and in markings, with this very marked difference, that the sub-marginal area 

 between the dark marginal lunules and the sub-marginal line, is much paler 

 than any other portion of the wing, throwing out by contrast these dark lunules 

 very conspicuously ; (ii). ab. fusca (n. ab.), of which three specimens were 

 exhibited, are undoubted L. gueneei 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 grotind coloiu- is much 

 darker than in typical examples, very dark grey with, in a good light, faint 

 flushes of a ferruginous tint. The contrast between grovmd colour and markings 

 is very much stronger than in any of the other forms. Mr. Champion, on 

 behalf of Mr. J. H. Keys, the black variety of Athous hxmorrhoidalis, F., from 

 Dartmoor, recorded by the latter in the Ent. Mo. Mag., xlvi, p. 262 ; and also a 

 red variety of the ^ of Agahus bipustulatus, L., from the same locality. The 

 Rev. A. T. Stiff, who was present as a visitor, exhibited some second brood 

 specimens of Polygonia c-alhum var. Imtchinsoyii. The vars., including three 

 intermediate, emerged on October 16th, 19th (:3), 20th, 21st (2), 22nd, 23rd and 

 26th, 1910. It is believed that there is no record of var. ludchinsoni having
