 at about middle ; the anterior tibia are only slightly curved. 



On various VmbeUifercB ; the larva has been observed in France on Helosciadium 

 nodiflorum and Crithmum maritimum ; the species is often found at the roots and 

 by sweeping in marshy places ; local, but not uncommon where it occurs ; Barnes, 

 Shirley, Forest Hill, Northfleet, Higham, Dnlwicb, Netting Hill, Hammersmith 

 Marshes, Esher, Cowley, Merton, &c. ; formerly common in Battersea Fields, near

B. alternans, Steph. (Juh'ni, Sahib.). Very like the preceding in 

 appearance and general structure, but on the average rather longer and 

 easily distinguished by the absence of tessellated small black patches on 

 the elytra, which are banded with alternate uninterrupted lines of brown 

 and light scales ; the thorax has three lighter bands, the central one 

 being often more or less obsolete, and is closely and rather coarsely 

 punctured ; the striae of the elytra are rather fine ; the head has a deeply 

 impressed stria on the vertex ; the antennae are red or pitchy-red with 

 the club darker, and the legs are pitchy-red or blackish, with the tarsi 

 often lighter; the colour of the scales is somewhat variable. L. G 7 min. 



Marshy places; at roots of plants, Ac.; often in company with the preceding 

 species, of which it has by some authors been regarded as a variety ; very local, but 

 sometimes not uncommon where found ; Battersea ; Xottin? Hill ; Barnes : Lee ; 

 Hammersmith Marshes; Eastry ; Rudhain, Xorfolk; Pegwell Bay; Sandwich; it 

 appears to be almost confined to the south-eastern counties of England. 



K. polygon!, L. (nrator, L.). Of shorter and broader form than the 

 preceding species, which it somewhat resembles in coloration ; black, 

 thickly clothed with greyish, brown and black scales, which are arranged 

 in lines ; head with whitish scales, antennae ferruginous with club 

 fuscous ; thorax subtransverse, with the sides slightly rounded, and with 

 three very distinct testaceous or whitish lines; elytra with distinct 

 punctured striae, with the suture in front white, posteriorly chequered 

 with black and white, disc with three abbreviated dark brown or black 

 lines, alternating with elongated white ones, one dark brown or black 

 line on each side of scutellum at base, and two on each side meeting or 

 approaching one another near apex, being most conspicuous ; legs reddish 

 or pitchy red, anterior tibiae with a tooth or raised prominence towards 

 the middle of the inner margin. L. 5 G mm. 



On Leguminosce ; also on Polygonum, Lychnis respertina, Silene inftata, &c. ; 

 common and generally distributed from the Midlands southwards ; Manchester dis- 

 trict, general on the coast, the larrae feeding on Lychnis and capsules of Silene 

 (Chappell) ; rarer further north ; Northumberland aud Durham district rare ; Scot- 

 land, occasional, Solway, Clyde, Forth, Tay, Moray, and probably other districts;
