106 ADEPHAGA. [Be}7ihidiur7h 



i. Antennae with the first three or four joiuts red . . . B. assimile. Gt/ll. 

 ii. Aiiteniia? with the first joint only red B. Clakei, Dates. 



B. fumig-atum, Duft. In general contour and appearance this 

 species agrees very closely with the KofapJnis group, and especially 

 resembles B. adustum; it is, however, distinguished from all the 

 members of that group by the double frontal furrows, and the fact that 

 the striai of the elytra are evanescent at sides and apex ; the head and 

 thorax are obscure greenish bronze, elytra testaceous spotted or banded 

 with black, or black with testaceous markings, as in B. flammulatum, 

 &c ; antennae fuscous -with first two joints red ; thorax transverse, "with 

 sides rounded in front and c^^ntracted behind, posterior angles shai-p 

 right angles, dorsal furrovr distinct, base with a small deep fovea on 

 each side ; elytra ovate, fii-st stria next suture reaching apex, the next 

 abbreAriated, the others still more so, or evanescent ; legs testaceous. 

 L. 3-4 mm. 



Local, and not common, although occasionally plentiful where it occurs ; formerly 

 found at Xotting Hill and in Hammersmith Marshes; Swansea : Alverstoke ; Essex 

 and Lincolnshire Fens; not recorded from the north of England, Scotland, or 

 Ireland. 



S. assimile, GyU. (Spencei, Steph.). Bluish black or greenish ; 

 antenn;^ fuscous with three or four basal joints red ; thorax a little 

 broader than long, rounded in front, rather strong!}- contracted behind, 

 somewhat convex, posterior angles right angles, dorsal furrow terminated 

 in front and behind in a transverse depression, base with a deep but 

 small fovea at each angle ; elytra with a plain subapical spot and the 

 apex itself testaceous, with strongly punctured striae on disc, becoming 

 obsolete towards sides ; legs testaceous or reddish. L. 3 mm. 



Marshy places, amongst dehris of reeds, &c. ; local, but not uncommon ; Gravesend, 

 Sheerness, Chatham, Battersea ; Eeigate : Deal ; Hythe ; Isle of Wight ; Slapton 

 Ley, Devonshire ; Hornsea, Yorks ; Whittlesea Mere ; Lincolnshire and Cambridge- 

 shire Fens; recorded from Ireland, but not from the north-of England or Scotland. 



B. Clarki, Daws. Rather larger thaji B. assimile, from which it is 

 distinguished by its elytra being shorter in proportion, and by the much 

 greater breadth of the thorax .especially at base : it is also a brighter 

 insect and darker coloured ; the anteimae are pitchy with only the basal 

 joint red ; thorax with sides moderately rounded in front and not 

 strongly narrowed behind, posterior angles right angles or slightly pro- 

 minent, disc convex, base with a rather large fovea on each side; 

 elytra rather convex, strongly striated, the strice next sxiture very deep, 

 becoming more feeble towards sides, with a reddish testaceous subapical 

 spot near margin (sometimes almost obsolete), and the apex itself 

 often testaceous ; legs entirely reddish testaceous. L. 3-3 j mm. 



Marshy places, at roots of grass and in moss ; local and not common ; Lee, Strood, 

 Wimbledon; Ramsgate ; Thornton Ee^ervoir, Leicestershire; Shipley, near Horsham ; 

 Dorchester; Colchester; Scotland, rare, Tweed district. 



As Dawson, who first described the species, remarks (G. Brit. 199), in 

 its general structure and in the deep strias and punctuation of the elytra, 

 this species is allied both to assimile and ijilrijies, but it is a more
