the white spot between the first and second median nervules 

 well developed, as was sometimes the case in Pyrameis 

 atalanta, and always so in P. huntera. Thus these three 

 species were linked together hy a very insignificant dot ; 

 always present in one species, and occasionally appearing in 

 the other two. 



Mr. F. W. Frohawk exhibited a bred series of Smerinthus 

 tilice, L., showing considerable variation in extent of markings 

 and depth and hue of colour, one specimen being a remark- 

 ably rich red form. Mr. J. Jenner Weir remarked on the 

 way the series were arranged, showing the gradual passing of 

 the green into the red form. 



Mr. Dennis exhibited a very dark form of Vanessa catdui, 

 L., taken in S.W. Berks, i892,and Q-Kd.va'^Xtsoi Colias edusa,'Ph., 

 reared by him from ova obtained from a female captured in 

 August ; the larvae pupated in September, and the first imago 

 emerged on 13th November. 



Mr. R. South exhibited examples of certain malformations 

 in Lepidoptera, and read the following notes thereon : — 



No. I. Papilio machaon, L. — The malformation in this 

 specimen consists of an unnatural rounding off of the apex 

 of the left fore-wing and a shortening of the tail of the left 

 hind-wing. With regard to the short tail, this in itself, and 

 if it affected both hind-wings, would not be considered a 

 malformation, as there is a race of P. machaon inhabiting 

 Kashmir with exceedingly short tails. 



No. 2. MelitcEa athalia, Rott. — In this example the right 

 hind-wing only is shorter, but it is interesting to note that 

 the markings are almost identical, spot for spot, with those 

 of the fully-developed left hind-wing. The right antenna, 

 however, appears to be somewhat shorter than the left one. 



Nos. 3, 4, and 5. — Here we have a short series of mal- 

 formed specimens of the same species, i.e. Lycczna bellargus, 

 Rott. The first example (No. 3) has the left hind-wing 

 reduced to about one-half its proper size, but there is no in- 

 dication of any crumple or crease, and I cannot detect any 

 fault in the neuration ; the fringes are perfect, but slightly 

 narrower than on the normal right hind-wing. The ocellation 

 of the under-surface of this ill-formed wing is, however, 

 aberrant, and does not agree with that of its fellow. 



The second and third specimen of bellargus may be taken 

 together as they each exhibit the same kind of malformation, 

 but on opposite sides. Thus wc find that the outer margin 

 of the left fore- wing of No. 4 and the right fore- wing of No. 

 5 is slightly concave below apex, and that the apex itself is in
