[January, 



(p. 249) Motschulsky also describes (inter alias) the following new species : — 



Lathridius pini, 1. c., p. 236, pi. 6, fig. 3, Russia and England. 



L. undulatiis, p. 242, England and South Russia. 



Corticaria horealis (Wollaston, M. S.), 1. c., xl, i, p. 70, England, 

 (p. 246) Myrmecoxenus, still apparently gemcs incertce sedis, is transplanted by 



Motschulsky to the Cucujidce from the Lathridiiy to which it was referred by 



Lacordaire. 



(p. 255) Melolontha hippocastani is incidentally referred to by Perty (Mitth. Naturf. 



Ges. in Bern, 1867, 305) as M. vulgaris, var. 

 (p. 261) Cyplion coarctatiis and C. fuscicornis are S n,nd ? of the same species, 



teste Kies., Berl. Ent. Zeit., 1867, p. 407. 

 (p. 281) Cryphalus ahietds, Ratz., and C. tilicc, Gyll., arc identical, teste Feri^ri, 



Col. Hefte, ii. 



(p. 296) Donacia geniculata and D. l(Bvicollis, Thomson, Sweden, = D. sericca, 



partim. We shall of course fi.nd these two novelties here, 

 (p. 301) Plectroscelis Icovicollis, Thomson. Coleopterists must examine their P. 



concinna for this insect. 



It may probably be not generally known that Motschulsky, in Bull. Soc. Nat. 

 Mosc, xxxviii, 2, p. 291, describes a new species of CaralmSy viz., C. anglicus, taken 

 near London ! Vide Record Zool. Lit., 1866, p. 299. It is, of course, most likely 

 that in this i-efcrence, as in some, at least, of his other localities, he has made 

 some mistake. — E. C. Rye, 7, Park Field, Putney, S.W., December, 1868. 



Notes on Cryphalus hinodulus and Hylurgus pilosus. — On some aspens growing 

 near Abergavenny I have detected certain beetles, which are interesting not only 

 on account of their rarity but also on account of their habits. Last spring I 

 observed that two of these trees, which arc from 20 to 30 years old, had been 

 blown over in a manner similar to that in which poplars often suffer, viz., they had 

 been snapped across at about the level of their lower branches ; one of them had 

 fallen last winter, the other during the previous one. On both I found evidence 

 of their having began to decay before they pelded to the stonn, but the more 

 recent one was still so far alive as to be attempting to throw out leaves, yet many 

 of its branches had long been dead and one side of the stem was so also ; this I 

 soon foimd to be caused by a small beetle belonging to the family Hylesinidw. This 

 beetle, Cryphalus hinodulus, Ratz., appears not to have been taken in England 

 since its original capture by Mr. E. W. Janson at Highgatc ; and I may observe 

 that very few of my specimens present the (sexual) spines at the apex of the 

 elytra ; and that, when present, the spines are very small. This species, unlike 

 Eylesinv^ crenatus, which commences its attack close to the ground, first attacks 

 the branches, and then advances downwards. A colony is probably commenced 

 by one, or by a few pairs ; but they rapidly multiply. There are about a dozen of 

 the young aspen trees {VopuVii^ tremula) on which I find them, and of these, 

 besides the two already mentioned, they have this season killed a third tree. The 

 leaves which it threw out abundantly last spring are now all black and dead, and 

 I suspect that this is entirely the work of the present season. A fourth tree is 

 far gone, and several others are invaded. Like most of the Xylophaga, it only
