On Crucift-ni' ; I IIMVC never seen a Hritinh example of tliw species, but Steplicim 

 records it as " taken near Loini.ni, in Suffolk, and about Bristol." 



P. luridipennia, Kuts. Oblong-ovate ; head and thorax brassy 

 green, elytra shining reddish-brown, antennae testaceous darker towards 

 apex, hind femora brassy pale at the base ; in the descriptions the legs 

 are given as brassy green, but in the specimens I have seen they are of 

 a clear reddish-testaceous colour, with the exception of the posti-iir 

 femora ; the species is of the size and build of P. hyoscyami, but is 

 narrower ; its smaller size, more brassy colouring, and more finely and 

 closely punctured elytra will distinguish it from P. chrysocephala, of 

 which insect, however, I cannot but think it is an extreme and local 

 variety, which has been to a certain extent altered by its insular habitat. 

 L. 3|-4 mm. 



This species was discovered by Mr. Wollaston in Lundy Island, off 

 the coast of Devon, and has never apparently occurred in any other 

 locality. 



P. napi, Koch, nee F. (rapcp, 111.). Oblong-ovate or elliptical, 

 convex, under-side black, upper-side deep blue, head and thorax some- 

 times greenish; head small, antennae fuscous with base testaceous; 

 thorax about half as broad again as long, narrowed towards the front, 

 very finely punctured, often almost smooth on disc ; elytra broader than 

 thorax, with fine rows of punctures, interstices obsoletely punctured ; 

 legs reddish-testaceous, with the posterior femora nigro-aeneous, and the 

 tarsi more or less infuscate. L. 2-3| mm. 



Damp places ; on Crncifene ; more common in some districts than in others, but 

 generally distributed throughout the kingdom. 



P. cuprea, Koch (cupronifenx, Forst. ; herbacea, Foudr.). Oblong- 

 ovate, rather elongate, moderately convex, of a greenish-aeneous or 

 brassy colour, with a more or less distinct coppery reflection ; head 

 small, vertex distinctly punctured, front with a smooth triangular space 

 between the antennas ; thorax broader than long, nairowed in front, 

 closely and rather distinctly punctured; elytra long, depressed on ili.-r, 

 with rather fine but distinct rows of punctures, interstices obsoletely 

 punctured; legs reddish-testaceous, posterior femora nigro-aencnus, 

 anterior and intermediate femora often infuscate at base. L. 2i-3 mm. 



On low plants, especially Cruciferac ; sometimes on poppies ; not uncommon and 

 generally distributed throughout the greater part of the kingdom. 



P. instabilU, Foudr. (//in/**, W. C., nee Redt.). Very like the 

 preceding, but rather smaller, broader and darker, with the head and 

 thorax more diffusely and finely punctured and more shining, and the 

 striae of the elytra finer and almost effaced behind ; the interstices of 

 the latter are finely rugose and rather dull ; the legs are stouter than in 

 P. ruprea, and have the anterior and intermediate femora more 

 infuscate. L. 2-2 ram.
