Lobotrachelus, Motschulsky (l.c. p. 438) says that all the species de- 
scribed by him (Et. Ent. 1848, p. 73) under the generic name of Cce/o- 
sternus belong to this genus, of which he describes the following new Cin- 
galese species : — L. olivaccus, hifasciatiis, cinerascem, and fulvus, 1. c. p. 439 j 
and L. cmciatus, ohliquevittakis, piceofasciatiis, and setigenis, 1. c. p. 440.

Ceuthorhynchides. 
Ceuthorhynchus. The habits of the larv£e of C. glaucus and C. quadridens

Soc. Ent. Fr. 4® s(^r. tome vi. p. 172. 
Ceuthorhynchus suturellus (Gy 11.). W. Tylden records the occurrence in 
Britain of a species identified with this, but differing from Gyllenhal’s de- 
scription in certain points indicated by him. Ent. M. Mag. ii. pp. 266-267. 
Ilye also doubts the correctness of the determination (/. c. pp. 267-258). 
Ceuthorhynchus suturalis (Fab.) is also recorded as British by Power 
(Entomologist, iii. p. 80). 
Pachyrhinus. Power (Entomologist, iii. p. 80) records the capture of a 
species of this genus new to Britain, which proves to be the true P. 4- 
nodosus (Gyll.), whilst the species previously recorded under that name is 
P. denticollis (G}dl.).
