somewhat securiform, and the first joint of the middle tarsi is not 

 thickened. In my specimens the elytra are not widened behind as in 

 2V. aquaticus, but are more gradually narrowed towards the apex. 



2V. lujpocrita has the tibiae reddish ; it is narrower and more con- 

 vex than N. palusfris, and the external interstices of the elytra are 

 distinctly alutaceous. It bears somewhat the same relationship to 

 N~. palusfris as N. substriatus, Wat., does to i\T. biguttatus, I\

TWO NEW BRITISH BEETLES. 

 BY J. It. LE B. TOMLIN, M.A., E.E.S., AND NOEMAN II. JOT, M.E.C.S., F.E.S. 



LlTARGUS COLOBATUS, Rosenh. 

 Resembles L. bifasciatus, F., in general colouring, but is easily distinguished 

 by its shape, smaller size, and more shining appearance ; it is broader in proportion 

 to its length, not so parallel-sided, and more abruptly narrowed in front and behind ; 

 the pubescence is longer and yellower, and the punctuation is much finer ; the club 

 of the antennse is narrower, the last joint in particular being much longer ; the 

 thorax has only a very slight trace of a longitudinal impression at the base. 



Long., 2-2-2 mm. 



Mr. J. Ray Hardy took fourteen specimens of this species in 

 June, 1907, in Sherwood Forest, from a fungus growing on a dead 

 holl} r log, and from the leaves about it. 



LONGITAESUS NIGEERIMUS, Gyll. 

 A very distinct, moderate sized species; colour entirely black, with a slight 

 aeneous reflection on the upper side ; tarsi pitchy ; antennae rather long and slender ; 

 thorax distinctly and diffusely punctured, but sometimes almost smooth; elytra 

 broad, with well-marked shoulders, strongly and rather thickly punctured. 



Long., 2'5 mm. 



Easily distinguished from all our other dark coloured species by 

 its large size and black antennae and legs. 



Dr. W. Wallace, of Grimsby, took four specimens by sweeping 

 at night on September 7th, 1907, near Cleethorpes, Lincolnshire, and 

 there is an example in Mr. Tomlin's collection labelled " Greathide." 

 In the 1891 European Catalogue, L. nigerrimns is recorded from 

 Britain, but we do not know on what authority ; the last Catalogue 

 gives " Northern Europe " only.
