Tomicus. — The recent researches of MM. Eichoff and 

 Chapuis have shown tlie necessity of subdividing this genus. 

 The sections thus established diflfer principally in the parts 

 of the mouth, and must be maintained as genera on any con- 

 sistent principles. 



Cryphalus Abietis. — It has been recently shown that this 

 species is identical with C. asperatus, Gyll., which name it 

 will have to take. 



Dendroctonus, Erichson. — The type of this genus is D. 

 micans, the finest of the European species of this group, and 

 one not hitherto found in England. 



Hylastes rufus. Marsh. — This name has been restored, as 

 far earlier than Gyllenhal's, and as being recognizably de- 

 scribed, more so in fact than the generally received H. 

 obscurus (Trifolii, Mull.) 



Baris Abrotani, Germ. — The name " picicornis," used for 

 this insect by VV^alton, seems to be hardly desirable. It is 

 certain that B. Abrotani and B. Lepidii were confounded, 

 and, from their relative distribution, probably the latter was 

 the type : certainly Stephens had B. Lepidii in view. Hence 

 in the confusion it will be best to ignore the name " jnci- 

 cornis." 



Ceuthorhyncluis versicolor. — This species has only six 

 joints in the funiculus, as remarked by Thomson, and differs 

 in that respect from the true quercicola, Fabr.., which has 

 seven, and is consequently a true Ceuthorhynchus. 



C. pallipes. — Under this name I have intended to de- 

 signate the curious variety found hitherto only on Lundy 

 Island by Mr. Wollaston. It resembles C. contractus in all
