24 per cent, produced dark ones and ~j\ per cent, died before 

 pupation, some in a futile attempt at hibernation. The 

 darkening is an extraordinary extension of the fuscous 

 shading of the type. Another point is the general streaki- 

 ness longitudinally in an irregular manner, of some indivi- 

 duals, for which the varietal name of substriata may be used. 

 About half a dozen specimens are aberrant ; four are asym- 

 metrical, typical on one side and streaked on the other." 



Miss Margaret Fountaine exhibited Picris napi, var.Jiavcs- 

 cens, ? , from Modling, near Vienna, a very local form of the 

 summer brood, occurring, as far as is known, only at Mod- 

 ling. The ground colour is a rich ochre, and the black 

 markings, especially in one of the specimens exhibited, 

 extends over the greater part of all the wings. 



P. daplidice, showing an extreme form of var. bellidicc, 

 from Aix-en-Provence in April, in which the green is very 

 broadly extended over the hind wings on the under side ; 

 and a typical specimen of the summer brood. Also ab. 

 raphani, from Algeria in July, in which the green markings 

 are entirely absent from the central area of the hind wings. 



P. chlovodicc, <§ and ? , summer brood, from Asia Minor. 



Anthocharis cardamines, $ and ?, with all the closely-allied 

 "orange-tipped" Anthocharis, including A. gruneri, from 

 Greece; A. damone, from Syria; .4. cuphenoides, from the 

 South of France; and A. enpheno, from Algeria. Also spe- 

 cimens of A. bclemia and A. fallout, from the desert district 

 in /\lgeria, showing the distinction between these two closely 

 allied species to be quite unmistakable. And finally, A. 

 pechi and A. charlonia, also from South Algeria; with A. 

 tagis, v. bellczina, from Aix-en-Provence, in April ; and v. 

 insidaris, from Corsica, in May. 



A long series of Melitcea didyma, taken over an area of 

 some thousands of miles, and presenting a good deal of 

 variation in both sexes ; the inclination being that those 

 from Spain and Western Europe, were large and heavily 

 marked, while those from Asia were smaller and very much 

 more sparingly marked. 



Mr. Hy- J. Turner read a paper entitled " Our Authorities : 

 an Introduction to Entomological Literature " (see page i), 

 illustrating his remarks by a number of volumes of works 

 issued previously to 1800, exhibited by Messrs. Adkin, 

 Edwards, Sich, and himself.
