carpini, Koch, on hornbeam. 



These are all admitted by Signoret to be good species, and he adds nine others 

 as European, all of which are doubtless to be found in Britain. They arc —

JeUneki, Frauenf., on laurustinus. 



aceris, G-eoffr., on Acer pi atanoides (not a native tree, but introduced 



from Europe nearly 200 years ago, and now common); 

 probably also on sycamore and maple, as in the parallel 

 case of Rhinocola aceris {vide vol. xiii, p. 42). 



In the Verh. d. k. k. zool.-botan. Gesells., 1867, Herr von Frauenfeld enumerates 

 the species of Aleurodes known to him, including A. enphorbice, Low, fomid on 

 Euphorbia peplus, but while he reckons it as doubtfully distinct he does not indi- 

 cate the species to which it may possibly be referred. 



There exist, therefore, with regard to the natural history of Aleurodes, not 

 only much that is curious, but also, considering the paucity of observers, the great 

 probability of much remaining to be learned, and of new species to be discovered. I 

 liave too little opportunity of working in this direction to be able to entertain the 

 expectation that I can do much, but I have written this note in the hope of enlisting 

 the attention of British entomologists, possibly of some of those who have been accus- 

 tomed to rear small Lepidoptera, or, at any rate, of some of the more enterprising of 

 the rising generation of investigators. — J. W. Douglas, 8, Beaufort Grardens, Lewis-

Secretion of toater -beetles. — The following curious note from Mr. T. T. Cooper's 

 ''Mishmee Hills " (King & Co., 1873), p. 178, has naturally escaped the attention of 

 M. F. Plateau, who, in his learned treatise " Sur une Secretion propre aux Coleop- 

 " teres Dytiscides" (Ann. Soc. Ent. Belg., xix, pp. 1 — 10), would otherwise, doubtless, 

 have had something to say upon its subject : — "In the evening, when we camped, at 

 " the Bramapootra, some of the men collected a. number of edible beetles. These 

 " little insects, which arc a species of water-beetle, are found in immense numbers 

 " during the cold weather in the dry shingly bed of the Upper Bramapootra. They 

 "are about the size of a finger-nail, with bronzed wing-shields, and when handled 

 " exude a liquid resembling walnut-juice, of a strong but not unpleasant odour. The 

 " Khamtees seemed to consider them a great delicacy when boiled, and for several 

 " days the odour of the beetles seemed to imfreghate their bodies, to their intense
