NOTES AND OBSERVATIONS. 129 



departures from tlic normal are only found in certain localities. It 

 is therefore interesting to observe that the intercalated pair of 

 antennfe is not, as regards the club, conformable with the natural 

 antenna of this individual, being, in fact, five-jointed instead of 

 four-jointed. We have, in fact, the antennae of one variety 

 added to those of an individual that itself is of a different variety ; 

 just, as we have already seen, we have in the case of h a right- 

 hand structm'e formed on the left-hand side of the body. 



It is seen from our figure that the joint 2, which is the com- 

 mon property of two antennae, is evidently a double joint. Now, 

 as the scape, sc, is the common property of three antennae, it 

 would be interesting to examine whether it bears any trace of a 

 triple structure ; it is evidently thicker than natural, but this 

 may only be due to its having a thicker joint 3 than is natural. 

 The structure of the joint 3 is amongst the most peculiar of the 

 questions that are suggested : according to the view we take it is 

 part of b and c, right-hand and left-hand structures. Is it a 

 double joint, and is one side of it left-hand, the other right-hand ?

NOTES AND OBSERVATIONS. 



Note on Aporia crat^gi. — Eeferring to the occurrence of this 

 species in open places rather than woods, Mr. W. Warde Fowler, in 

 ' Nature ' (No. 1320), says that iu the years 1857-1859 he used to find 

 it " tolerably abundant" on a common about a mile and a half to the 

 west of Cardiff. This common was quite an open one, without any 

 adjacent woodland and very little hedge timber. In No. 1321 of the 

 same periodical Mr. Goss states that he met with the species "in 

 abundance in the New Forest in 18GG, 18G8, 18G9, and 1870." He 

 adds, " It rarely occurred in or near dense woods, but preferred the 

 open heaths and wastes of the Forest, where thistles were plentiful. 

 In 18G7 I found the species swarming, about midsummer, in hay-fields 

 on hill-sides in Monmouthshire. There were a few small orchards, 

 but not much wood in the neighbourhood." 



Ee a Hunt for Phorodesma smaragdaria. — Having just received 

 the March number of the 'Entomologists' Monthly Magazine,' and 

 read Mr. Auld's description of a hunt for P. smaragdaria, I am simply 

 amazed to think that in these matter-of-fact times we should have a 

 veritable Rip van Winkle arise in our midst to tell us this old story, 

 which we all knew so well, as sometldwj new. Or is it that we live in 

 such very fast times, that the discovery of this particular larva about 

 eiglit years ago, when its whole history was made known, has already 

 become ancient history, and the true facts lost in the dim past ? that 

 we are treated to this mythical, and not very elevating anecdote, of the 

 •' beetle-catcher and his friend," which, I need hardly say, existed only 

 in the imagination of the narrator. The memory of my late friend 

 (Mr. Machin) alone induces me to notice Mr. Auld's absurd statement, 

 and to inform him that the correct account is to be found in the
