In order to explain in possibly explicit manner the sculpture on 

 the declivities of the described new species, the subjoined figures are 

 given for comparison of these declivities belonging to two other spe- 

 cies known from Russia x ). One of them, Carphoborus minimus Fab г., 

 makes its galleries in the Pinus silvestris L. and is distributed over 

 the middle and south of Russia as well as over nearly all Europe; ano- 

 ther, Carphoborus rossicus Sem. 2 ) bores in Picea and was found, till 

 now, only in this country, Government Vjatka. Carphoborus minimus 

 Fabr. (fig. 3) somewhat resembling Carphoborus cholodkovskyi, sp. n. 

 has scarcely visible tubercles only on the interspace 3rd, whose end 

 is joined only to interspace 9ht. As to Carphoborus rossicus Sem. 

 (fig. 4), this species is to be distinguished from all other Carphoborus 

 by its ribbed elevated till their base, interspaces 1st, 3rd, 5th, 7th and 

 9th and by shortened and separated interspaces 5th and 7th. 



1 ) The 5rd species of this genus found in Russia (East Sibiria, Jakutsk) 

 and described according only one specimen by E g g e r s as Carphoborus ju- 

 rinskii (Eggers. Ent. Blatt., 1910, p. 36) is unknown to me.
