114 ADEPHAGA. [^BemUdluM. 



B. quadrig-uttatum, F, Head and thorax brilliant black, with a 

 brassy or greenish reflection, elytra black with four light yellow patches, 

 two at shoulders more or less triangular, and two round ones before 

 apex ; forehead with two strong parallel furroAvs ; thorax about as long 

 as broad, cordiform, very convex, with sides rounded in front and 

 strongly but gradually contracted from about middle to base, posterior 

 angles almost right angles but scarcely prominent,dorsal line distinct, basal 

 foveae deep ; elytra oblong-ovate, with punctured strife plain towards 

 base only, smooth from middle to apex ; legs testaceous, femora (at least 

 above) and knees dark. L. 4-5 mm. 



Sandy banks of ponds, streams, and rivers ; common and generally distributed in 

 the southern and midland districts ; local, but not rare in the north. Scotland, rare, 

 Lowlands, Tweed, Forth : a small variety occurs at Luccombe Chine, Isle of Wight, 

 which Mr. Gorham discovered in company with Dr. Sharp and myself, and which we 

 thought at tiist must be B. quadripusttdatum , the smallest specimens being only 

 from '6 to 3i mm. in length. 



B. quadripustulatum, Dej. (Fig. Ent. Annual, 1871). Inter- 

 mediate betAveen the preceding and B. quadrimaculatum ; from the 

 latter it differs in its larger size and dark legs, from the former in its 

 smaller size, shorter build, more transverse thorax, smaller and rounder 

 elytral spots, and much more regular sculpture of the elytra, the punctured 

 striae extending much further towards apex ; from both species it may , 

 be distinguished by its entirely black antennae. L. 3|-4 mm. 



Rare ; first taken by Mr. Gorham in a marshy place at Bearsted near Maidstone, 

 and afterwards at Rusper nt-ar Horsham ; one specimen was recorded from Repton, 

 Burton-on-Trent, by the late Mr. \V. Garneys. 



B. quadrimaculatum, Gyll. Head and thorax dark metallic 

 greeii or brassy black ; elytra black, with four light yellow patches 

 shaped as in quadriguttatum ; thorax sciilptured as in that species, 

 distinctly broader than long, with the posterior angles acute, minutely 

 prominent ; antennae dark with four basal joints red ; elytra ovate, with 

 fine but distinct punctured striae reaching nearly to apex, evanescent at 

 sides ; legs entirely testaceous, femora sometimes dusky. L. 3 ram. 



Damp and sandy places near ponds or streams ; common and generally distributed 

 in the southern and midland districts, local in Yorkshire and Lancasliire, but ap- 

 parently entirely wanting in the extreme north ; I can find no record from the 

 Northumberland district, Scotland, or Ireland, but it probably occurs in the latter 

 country ; according to Schaum it is abundant over the whole of Europe, and also in 

 North America, where it appears as B. oppositum. Say. 



B. lunatum, Duft. Blackish or greenish bronze, shining, elytra 

 with a very distinct more or less crescent-shaped orange spot on each on 

 the posterior third, which meet or almost meet at suture ; antennae dark 

 with three basal joints testaceous ; thorax transverse, convex, rather 

 short with sides very strongly rounded in front and contracted behind, 

 posterior angles acute, projecting, dorsal furrow distinct, basal foveae 

 deep, base coarsely punctured ; elytra about twice as broad as thorax at 

 base, rather depressed, with very deep, plainly punctured striie, which
