of the Lake of Retournemer, Vosges ; August 1918, at Hardelot, Pas- 

 de-Calais. At Retournemer larvae were in plenty on the leaves of 

 Comarum, with imagines. Among hundreds of specimens there is a 

 certain proportion of small and very dark ones, quite identical with my 

 Scotch example of fergussoni ; but, on the whole, size and colour seem 

 to be extremely variable. It seems probable that the GalernceUa of 

 Comarum is a distinct species from that found on Nymphaea, but I am 

 not quite sure that it is really separable from G. sagittariae Gyll. I 

 ma}' state here that many Galenicinae present in their ethology a 

 ciu'ious instability, various species of the same genus, even variovis races 

 of the same species, feeding on very different plants. An intei'esting 

 contribution to these facts has been recentl}^ published by my friend 

 P. de Peyerimhoff : it is the natural histor}' of Galeruca violacea, an 

 Algerian beetle feeding equally on Pulicaria and Rumex {cf. Ann. Soc. 

 Ent. Fr. 1915, p. 34). Analogous observations are reported on certain 

 species of the genera Bromhis and Graptodera. 



Bari/pithes .dupUcatiis Keys. — ^This species and B. p&llKcidifs have 

 in France separated areas, and they do not occur together. B. diij>li- 

 catus has a marked western range: 1 know it from Mortain, INTanche; 

 Pennes ; Morlaix and Brest, Finistere ; G-uerande, Loire-Inferieure, and 

 Limoges. At Boulogne-sur-Mer and in the vicinity of Niort I have 

 found only pelhicidiis, which, of course, is a very common beetle in 

 Northern and Eastern France, extending to AVestern Germany. 



Anfhonom^is ri/hi, v. comari Crotch. — I took a specimen of this 

 curious small weevil at Hardelot, Pas-de-Calais, where it probably feeds, 

 as in England, on Coinaritm palustre L.

SOME XOTES ON CETONIA AURATA. 

 BY K. Cr. I5LA1B, B.Sc., F.E.S. 



Baring the month of July the handsome Rose Chafer {Cctonia 

 aurata L.) was very abundant on the island of St. Mary's, Sci]l_y, 

 though strangely enough its distribution appeared to be practically 

 limited to the immediate coast on the eastern side of the island. Here 

 the insect was in numbers, during the early part of the month upon the 

 tlower-heads of thrift, but when this began to get over it preferred the 

 flowers of the wild carrot and bramble. Occasionally a Chafer would 

 fly past in the sunshine, but for the most part they were engrossed in
