NEW BRITISH SPECIES, ETC., IN 1866. 91 



90. PACHYRINUS(PHYT0BIUS)DENTIC0LLIS,(Gyll.)Sch6n., 



Syn. Ins. iv, 584, 9 ; J. A. Power, Ent. 29, p. 80. 

 4-nodosuSj Wat. Cat., nee Gyll. 

 Dr. Power records the capture by himself at Lee of six 

 examples of a Pachyrinus living only in marsh-ground, 

 larger, more coarsely tuberculated, and with a shorter thorax 

 than the insect usually found in dry and chalky places, and 

 which represents the P. 4-?iodosus of our Catalogues. These 

 marsh specimens have been returned from M. Brisout de 

 Barneville as the true P. 4-7(udosus of Gyll. ; and the insect 

 formerly known to us by that name is considered to be P. 

 denticollis by M. Brisout. 



91. Ceuthorhynchus suturalis, Fab., Gyll., Schon., 



Syn. Ins. iv, 478, 4; J. A. Power, Ent. 24, 13. 

 A single specimen has been taken by Mr. J. Sidebotham, 

 in the spring of 1885, crawling on the sand, "on the Welsh 

 Coast." On the continent it appears to be rare, living on 

 sallow. It is about the size of a large C. sulcicollis, has un- 

 dentate femora, and may be at once known by the broad line 

 of white scales which extends from its neck to the apex of its 

 elytra. 



92. Ceuthoryhnchus suturellus, (Gyll.) Schon., Syn, 



Ins. iv, 558, 119 ; Rev. W. Tylden, Ent. Mo. Mag. 



vol. ii, p. 256. 

 Mr. Tylden records the capture near Hythe in May, 1865, 

 of specimens of a Ceuthorhynchus , allied to C. cyanipennis, 

 from a species of Cardamines, which he brings forward with 

 doubt as the suturellus of Gyll. These insects appear to be 

 specifically identical with others belonging to Mr. Crotch, 

 which were pronounced by M. Brisout (who had compared
