NEW BRITISH SPECIES NOTICED IN 1857. 65 



and 7 th) with a somewhat obscure ridge, the posterior 

 margin of the apical (1th) segment acutely serrate. 

 Length \\ lines. 

 Antennae half as long again as the head, robust and com- 

 pact, gradually incrassate towards the apex, joints 5 to 10 

 fully twice as broad as long, the apical joint as long as the 

 two preceding united, acuminate, pitchy black, the two basal 

 (1st and 2nd) and the apical (11th) articulations and the 

 palpi rufo-testaceous. Head thickly and finely punctate, 

 opaque, pitchy- black. Thorax nearly twice as broad as long, 

 wider than the elytra, narrowed in front, rounded at the 

 sides, the posterior margin lobed in the middle, deeply 

 notched towards the angles, which, although prominent, are 

 obtuse, sub-opaque, very thickly and rather deeply and 

 coarsely punctate, the punctures oblique and confluent, thus 

 giving to the sculpture a peculiar undulated appearance, with a 

 short scattered golden pubescence, pitchy-black, the margins 

 obscurely rufous. Elytra barely as long as the thorax, simi- 

 larly but not quite so strongly punctured, the outer posterior 

 angles with a deep notch, sparingly clothed with a short 

 golden depressed pile, sub-opaque, of a bright chestnut hue, 

 the region of the scutellum and the lateral margins faintly 

 pitchy. Abdomen shining, gradually narrowed towards the 

 apex, thickly minutely punctate, the punctures sparser on the 

 terminal segments, clothed, especially at the sides, with a 

 longish somewhat depressed golden pubescence, rufo-tes- 

 taceous, the fifth entirely and the base of the sixth segments 

 pitchy-black. Legs of a clear testaceous red. 



N.B. The above description was drawn up soon after the 

 specimens were captured ; the rufo-testaceous colour 

 of the abdomen has since deepened into brown, the 

 apical half of the penultimate (6th) and the entire 

 terminal segment alone now retaining that hue.
