110 THE entomologist's KECORU. 



other species niiglit have specially male characters developed in the 

 pupa. An examination of the pupa-cases of the species exhibited 

 to-night yielded the following results : In ;S'. pavonia, I), pudihimda and 

 0. dispar the antennae- cases are nearly as well developed in the female 

 as in the male pupa, whilst in the imagines the antenna} are only very 

 slightly pectinated in the J and only occupy a small portion of the 

 space covered by the pupal cases. In li. querent there is no develop- 

 ment suggestive of })ectinated antenn;e in the pu])a, though the antennje- 

 cases arc ratlier more raised in the male than iu the female pupa ; in 

 (). potatoria the development is hardly noticealile ; in the imagines ol 

 lioth species the pectinations are strongly marked in the J s, slightly 

 so in the 2 s, the latter species being rather the more favoured in this 

 respect. From these facts I am inclined to think that tlie first group 

 have evolved from a type or types that had the pectinations of the 

 antennai well-developed in both sexes and in which, probabl^^, either 

 sex would be attracted by and fly to the other, that the J s subsequently 

 lost the pectinations through disuse, whilst in the ^ s of S. paiwuia 

 they have been still further developed. In the second group the 

 evolution would seem to have been from simple to })ectinated antemue, 

 the (J s having advanced farthest in this respect, whilst the puptB have 

 not yet fully res])onded to the change." Mr. Koutledge exhibited a 

 collection of Coleoptera taken l)y him near Carlisle, auiong them being 

 Silplia ni(/rit(i, Cocclnclhi \A-pnnctat(i, Pterostichns versicolor, Aviara 

 ontt(t, Limoiiiiis cijIlndyicnH and liavynotus schimhcrrl. Mr. Tutt read a 

 })ai)er on " Nature's Scents," in which he pointed out that, as a rule, it 

 was the inconspicuous flowers which had the richest perfume, blue and 

 reil flowers being mostly devoid of odour ; that this development oi 

 })erfume subserved the purpose of attracting insects to the blossoms and 

 so ensured cross-fertilization ; other scents, both in the animal and 

 vegetable kingdom, were disgusting and jirobably subserved a jDrotective 

 function. Mr. J. A. Skertchley mentioned the case of a South American 

 flower which was of a dee}) red colour ; it was perfectly sc(;ntless by 

 day l)ut during the night, when its colour rendered it practically 

 invisible, it gave off a very powerful })crfnme ; the plant was visited in 

 large uumliers liy a species of a Hawk-moth. 



March, 20tJi, 18<J4.— Exhibits :— Mr. Prout ; a large number of 

 specimens of Coreniia feyriujarin, Haw., to illustrate his paper. Mr. 

 l)attley ; a living J and ova of Anisoptcri/x ncscuhiria, in Kiln, on a twig 

 of birch ; the eggs were deposited in a necklace-like ring, encircling 

 tlie twig just beyond a small shoot ; there were about 24 eggs, counting- 

 round the twig, and the band varied from 4 to 9 eggs in width, so that 

 in all there were 150-200 eggs. They were covered with down from 

 the anal tuft, and appeared to l)e ovoid in shape, and attached by their 

 smaller end. I )r. Secpieira ; Aiaphidasi/s strataria, FdnoJis piniperda, 

 lli/beriiid Iciicojiliedvia, Alencix piciaria, all ])red, from the New Forest; 

 also several beautiful varieties of Larcntiacaesiata, Mclanippe montanata, 

 Mclanthia (dhicillatd, and 31. bicolorata. Mr. Goldthwait ; Colias edusa, 

 with var. heJicc, and intermediate forms ; one of the C. edusa had the 

 marginal pale spots so strongly developed on the hind wings, as almost 

 to form a band. Mr. Lane ; CaJocaiupa vetiisfa from Aberdeen. Mr. 

 ('. Fenn ; C. ferrugata and C. unidentaria, including a Scotch form of 

 the latter, and a specimen with tlie median liand extremely narrow. 

 Tiiese two species were also exhibited l)y other members. Mr. Bayiie ex-
