In the summer of 1915 the first-named of the authors of this worlc 

 collected a great number of bark-beetles of the genus Scolytoplatypus, 

 Blandf., from a forest containing both deciduous and coniferous trees, 

 near Vladivostok. These beetles are on the wing in May and June and 

 occur mostly in shaded, damp places. A variety of trees were cut 

 down and left as baits, and it was found that the most attractive were 

 maples, xicer mono and A. tnandschimcwm. The galleries of these 

 beetles, which resemble those of S. tycon, Blandf., occurring in Japan, 

 are described. The authors believe that this species will prove to be 

 new and call it provisionally, S. ussuriensis, sp. n. An English 

 summary is appended and contains also a description of some of the 

 characters distinguishing the females from the males.

This is a description in EngHsh of two new species of Carphoborus, 

 viz :— C. cholodkovskyi, sp. n., found under the bark of dying Pinus 

 silvestris, and C. teplonchovi, sp. n., found in that of dead Picea 

 obovatu and Abies sibirica, in Perm and Vologda. The galleries of both 

 these Scolytids resemble those of C. minimus, F., which occurs on 

 Pinus silvestris all over central and southern Russia and nearly the 

 whole of Europe, and of C. rossicus, Sem., boring in Picea, which also 

 occurs in Russia.

This report covers the first year of the existence of the Bureau and 

 gives an elaborate account, containing many tables, calculations and 

 formulae, of the investigation as to the pests of clover carried out on the 

 lines laid down by the Tula conference [see this Review, Ser. A, iv, 

 J). 292 sqq.]. The conclusions arrived at are summarised as follows : 

 Apion sp. is undoubtedly a pest of clover seed, and in the year under 

 report it has caused damage varying from 5 to 36 per cent, and a 

 reduction of seed varying from 2 to 55 per cent. The weevils injure 

 both pollenised and unpollenised flowers, the percentage of the shortage 

 of seed roughly approaching that of injured flowers, though there is no
