viz. glaiica, undnlata, indica (from America only !), shooterii, 

 etc., practicall}^ perfect transitions from immaculate pale 

 yellowish individuals (or pearly white as in undnlata) — 

 leucochroic — to almost immaculate black individuals — me- 

 lanochroic — are found in the same locality and at the same 

 time. These colour variations appear to be casual, and in 

 no way affected by the operations of natural selection. It 

 may be remarked that the dark N . irrorata is very common 

 in the United States, while the usually pale N . glauca of 

 Europe and N. undnlata of America are exceedingly common 

 throughout their area of distribution, the general conditions 

 being apparently much the same in all cases. The species 

 do not as a rule vary very greatly in size, except the protean 

 A'', undidata. 



"Note specially the three forms of N. mexicana, red, black, 

 and pale olive ; also the very rare immaculate form of A^. 

 glauca, var. macidata from North Africa. This has the usual 

 yellow and black abdomen of var. macidata.'''' 



Mr. W. J. Kaye exhibited a specimen of Papilio machaon 

 from Wicken, with the submarginal band of the fore-wings 

 internally edged with a broad black band, and with the dis- 

 coidal spot enlarged into a black blotch, which united with 

 the black band ; and a specimen of Hydrocampa stagnah's 

 with the basal black line obsolete, the inner edge of the 

 double submedian line strongly indicated, and the outer edge 

 very faintly marked ; also the cross band between the two 

 transverse bands almost obsolete. 



Mr. A. Buckstone exhibited two varieties of Polyommatus 

 icarus (alexis) : (i) Female, taken at Dorking, August 12th, 

 1900. With the right upper wing of the male colour. 

 (2) Female, a very small specimen, smaller than several 

 Cupido minima (cdsus) in his possession, the under side of 

 both upper wings having two of the spots joined by a black 

 line. 



Mr. Newman exhibited a specimen of Smerinthns ocellatns, 

 from a larvae taken in the Bexley Woods, August, i8gg, 

 feeding on sallow. It emerged June 2nd, igoo. Unfor- 

 tunately a beetle larvae got at the body, and then grease set 

 in. A specimen of Noctna neglecta, a red form received from 

 Dr. Freer (Rugeley), and captured by him this season at 

 Cannock Chase ; and a dark form of Ennomos fuscantaria, 

 one of some 400 examples of the species which he bred this 

 year. It emerged this morning (8th). The first imago of 

 the broods emerged at the end of July, and others continued
