6S [August, 



Harli/ appearance of Colias Edusa. — Considering that most Lepidoptera are so 

 backward, it may be worth while noticing in the Magazine that I saw one very fresh 

 Colias Udusa yesterday, at Folkestone (a male, I think), oia the Eailway Bank, and 

 my friend, Mr. J. W. Q-ore, saw another on West Cliff. — Thos. H. Beiggs, Lincoln's 

 Inn : 24:th June, 1872. 



marly appearance of TriphcBna suiseqiia. — In former years, T. subsequa has 

 invariably followed janthina, orhona, and fimbria, never occurring with me before 

 August. 



None of the above three species have yet appeared, thongli, strange to say, I 

 took a female subsequa last night at sugar. It was in admirable condition, having 

 evidently just emerged. 



I also noticed lately, hovering over Ononis, evidently depositing their eggs, many 

 H. marginata ; several taken with the net were, however, 'passe. A. nebulosa, N. 

 brunnea, ]£. hccipara, and A. ligustri rare, and this year unusually abundant at 

 sugar, and N. conflua is becoming common. — -G-EO. Nohman, Cluny Hill, Fon-es : 

 7th Julij, 1872. 



'Note on the occurrence of rare Lepidoptera in the Isle of Man. — KefeiTing to 

 the annoimcement of the occuirence of rare Lepidoptera in the Isle of Man, in the 

 last number of this Magazine, page 44, I believe most entomologists will join with 

 me in desiring to know the details of their capture, especially as there are four 

 species mentioned which have not been jDreviously observed in the British islands ; 

 and I hope Mr. Hodgkinson will be kind enough to give yom- readers the benefit of 

 any information he may possess. 



I have no desire to criticise the somewhat novel method which Mr. Gregson has 

 chosen for allowing a knowledge of the existence of these treasures to ooze out, 

 because so great is the suspicion and doubt through which a new species has to 

 make its way to public recognition, that a modest man may well shrink from facing 

 it ; biit the mere mention by Mr. Hodgkinson that he saw certain insects in his 

 friend's cabinet is not sufficient to justify their introduction into the list of native 

 species. 



I regret to say that the prevalent disbelief of statements as to the occurrence 

 of new or even rare inse(?ts is more than justified by the frauds which have been 

 perpeti'ated through the introduction into England of large numbers of continental 

 Lepidoptera in the pupa state, which have been subsequently distributed as British, 

 doing no small damage to science by rendering the real facts of the distribution and 

 peculiarities of British insects almost impossible of attainment. — -Edw-in Biechall, 

 Airedale Cliff, Newlay, near Leeds : July 13th, 1 872. 



The relationship between colour and edibility in larva. — The note on this sub- 

 ject by Mr. Doubleday in the last number of the Ent. Mo. Mag., p. 45, does not 

 appear to me to tell agaiiist Mr. Wallace's explanation of the bright colours of cater- 

 pillars. The law discovered a priori by Mr. Wallace, and verified experimentally 

 by Messrs. Jenner Weir and A. G. Butler, only amounts to the fact that brightly- 

 coloured, hairy, and spinous larvse are refused by a lar<ie number of insectivorous
