ANISOT0MID.E. PHALACRUS. 161 



Extremely abundant throughout the metropolitan district, during 

 the greater portion of the year, but most so in the autumn. " Rivel- 

 stone-wood, near Edinburgh, under the bark of firs, in the winter." 

 — Dr. Leach. 



Sp. 6. coruscus. Brevior ovatus, valde convexus, niger, nitidissimus, elytris 

 loevibus, ad suturam unistriatis, pedibus nigris. (Long. corp. 1 — 1£ lin.) 



Ph. coruscus. Paykul.—Steph. Catal. p. 67. No. 701. 



Short, ovate, very convex, very glossy black : head very obscurely punctured : 

 thorax very convex, the disc most obsoletely punctured : elytra scarcely punc- 

 tulated, very convex, with an impressed stria on each near the suture, ab- 

 breviated anteriorly, head pitchy-black beneath, scarcely punctate : legs black; 

 clothed with ashy-down: antennae black, with the terminal joint rather 

 elongated and very acute. 



The deep black colour, smooth elytra, with a single stria on each, and very acutely 

 terminated antennae, distinguish this from the following species. 



Far from uncommon on flowers in the neighbourhood of London. 

 " On the flowers of Ranunculi, in Devonshire." — Dr. Leach. 



Sp. 7 . picipes. Brevior ovatus, convexus, niger, nitidissimus, elytris Iwvissimis, 



strid suturali unicd, pedibus piceis. (Long. corp. 1 lin.) 

 Ph. picipes. Kirby? MSS.—Steph. Catal. p. 67. JVo. 702. 



Less than the last: short, ovate, convex, black, very shining, head and 

 thorax as in Ph. coruscus : elytra very smooth, with a single sutural stria, 

 not abbreviated at the base: legs and antennae pitchy-black, the former 

 palest. 



I obtained this insect by the above name from Mr. Marsham's cabinet : it may 

 not possibly be more than a variety of the foregoing, with the legs paler, and 

 the sutural striae rather deeper and longer than usual. 



The locality is unknown to me, although I have captured the 

 insect myself. 



Sp. 8. substriatus. Brevior ovatus, valde convexus, niger, nitidissimus, elytris 



obsolete punctato-striatis. (Long. corp. 1 lin.) 

 Ph. substriatus. Gyllenhal.—Steph. Catal. p. 67. No. 703. 



Short, ovate, very convex, deep glossy black; head and thorax as in Ph. coruscus: 

 elytra impunctate, obsoletely but regularly punctate-striated, the striae an- 

 teriorly vanishing : body beneath and legs pitchy-black, the latter with an ashy 

 pubescence : antennae black, with the terminal joint rather large, narrower 

 towards the apex, and somewhat obtuse. 



The comparative obtuseness of the antennae and obsoletely striated elytra at 

 once discriminate this from Ph. coruscus. 



Found near London, and in Suffolk : also in Glamorganshire and 

 Norfolk.
