Retrospective Criticism. 377 



the strange irregular manner in which the figures are num- 

 bered, and the confused arrangement of the species in the 

 plates ; blemishes which, without possessing any counter- 

 balancing advantage, cannot but cause the reader much un- 

 necessary trouble and perplexity. Yours, &c. — W. T, Bree.

Retrospective Notices, by J. C. Dale, Esq., on Insects, in re- 

 lation to Remarks by Mr. Bree, Mr. Westwood, and others. — 



The Variety of Argynnh Agldia (Vol. V. p. 750., Vol. VI. 

 p. 175.) is very similar, on the under side, to one I have from 

 the cabinet of the late Dr. Abbot ; but, on the obverse, mine 

 scarcely varies from the common one, except in the liturse 

 near the base of the superior wings : and I have another spe- 

 cimen, taken near Peterborough, which completely decides its 

 being only a variety, being, on the reverse, Aglaia on one 

 side, and Caroletto on the other (or Ge6rgius of Dr. Abbot's 

 MSS.). 



The figure 122. (Vol. V. p. 749., Vol. VI. p. 175.) is un- 

 questionably also another variety of Aglaitf ; and very similar 

 to Mr. Curtis's figure (Brit. Ent..) of one caught in Ips- 

 wich : " the prevailing green tint of the posterior wings 

 beneath, and the small (smaller than usual) silver spots," I 

 have never observed in A. Adipp^. 



Fig. 124. (Vol. V. p. 751., Vol. VI. p. 175.), I think, is very 

 likely P. T>\a (but, without seeing a specimen, it is difficult 

 to pronounce decidedly, as the doing this depends chiefly on 

 the second wings beneath), and it is another example of the 

 additions made to our list of British Papiliones since the time 

 of Harris and Lewin, &c. An exact copy of P. Lathonia 

 (Latona) of Gamlingay, from Petiver, whose work is scarce, 

 would enable us to form a better opinion whether it be the 

 same species ; but I have also doubts about that, as my La- 

 thonia, taken by Dr. Abbot at Whitewood, Gamlingay, and 

 Shelford's also, which I have seen, are the true Lathonia. 

 Ray (p. 126.) mentions several being taken, in Cambridge- 

 shire, by Vernon, Antrobus, and others. Mr. Scoresby found 

 Colias Palae v no (and I have a pair of the same, alias Euro- 

 pomtf, from Russia, not Europomi St., or Philodic^ Godap., 

 which I also have from America) and Melitae v « D\a (purple 

 under-wing fritillary), in great numbers, on the east coast of 

 Greenland, 71° N. 



The fine Procerus tauricus being found in Siberia extends 

 the hope that this northern latitude may yet furnish further 

 novelties in entomology.
