MONOTOMID.^. 115 



R. oblongicollis, Blatch and Horner (Ent, Mo, Mag. xxviii. 

 (2 Ser. iii.), 1^92, o03) ; R. jmnctidatus, Guilleb, (Ann, Soc. Ent. Fr. 

 1897, Bull. 226). Of a ferruginous colour throughout, although the 

 head and thorax are occasionally dusky or pitchy ; the insect is more 

 cylindrical and convex than the other species, except E. nitidulus, F., to 

 which it most nearly approaches. Head rather elongate, very slightly 

 narrowed behind, scarcely as wide as the thorax, uniformly punctured, 

 the punctures being distinct and not close. Eyes rather small and not 

 very prominent, antennpe ferruginous, with an ovate club ; thorax 

 oblong, parallel-sided, with all the angles rounded, margined at sides and 

 base, punctuation not close, a little stronger than that of the head, a 

 distinct but very small space behind the centre smooth, base gently 

 emarginate. Elytra elongate, narrowed behind, rather finely and 

 closely punctured in regular rows, the sutural I'ows only being in evident 

 strijfi, punctuation at sides finer than on disc, interstices equal, flat, and 

 finely alutaceous, the sutural interstices only with a row of fine 

 punctures on each. Legs ferruginous . Abdomen and underside 

 punctured, the last ventral segment without any depression. 

 L. 3^-4 mm, 



Sherwood Forest, Notts, and Bagot's Park, Stafibrdshire, vmder 

 oak-bark (Blatch and Horner). Mr. Champion (Ent. Mo, Mag. xxxiii. 

 (2 Ser. viii.), 1897, 278) points out that this insect is evidently conspecific 

 with R. 2)unctulatus, Guillebeau, described from Nantua, Southern France : 

 this insect is stated by its author to difler from R.fei-rugineus, Payk. 

 and R. 2MrallelocoUis, Er., by the fine punctuation of the thorax, 

 and the shortness of the second joint of the antennae, and from 

 R. nitidulus, F., by its ferruginous colour and the absence of the fovea 

 on the last ventral segment. Mr. Champion possesses a specimen 

 from the Rev. T. Blackburn's British collection, without locality 

 attached. 



MONOTOMIDiE. 



MONOTOMA, Herbst. 

 M. Fauvel (Ent, Mo. Mag. xxxi. (2 Ser. vi.), 1895, 141), in a letter to 

 Mr. Champion, has pointed out that I am in error in considering 

 M. qitadrifoveolata, Aube, as synonymous with Jl. subqioadrifoveolata, 

 Wat.j and that the synonymy ought to stand as follows : 



1. 21. rufa, Redt., 1849 : 



JSubquadrifoveolata, Waterh. 

 Quadri-imjiressa, Reitt. 

 Ferruginea, Bris. 

 Quadrifoveolata^ Fowl. 



2. M. quadrifoveolata, Aube, Crotch. 



Sid>quadrifoveolata, Fowl. 



This alteration must therefore be made (y. Brit. Col. iii. p. 274).
