Psylliodes. | PHYTOPHAGA. 391 
On Cruciferz ; I have never seen a British example of this species, but Stephens 
records it as “taken near London, in Suffolk, and about Bristol.” ; 
P. luridipennis, Kuts. Oblong-ovate; head and thorax brassy 
green, elytra shining reddish-brown, antenne 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 posterior 
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. 33-4 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, nec F. (rape, Ul.). Oblong-ovate or elliptical, 
convex, under-side black, upper-side deep blue, head and thorax some- 
times greenish; head small, antenne fuscous with base testaceous; 
thorax about half as broad again as long, narrowed towards the front, 
very finely punctured, often almost smooth on dise ; elytra broader than 
thorax, with fine rows of punctures, interstices obsoletely punctured ; 
legs reddish-testaceous, with the posterior femora nigro-eneous, and the 
tarsi more or less infuscate. L. 2-35 mm. 
Damp places ; on Cruciferze ; more common in some districts than in others, but 
generally distributed throughout the kingdom. 
P. cuprea, Koch (cupronitens, Forst.; herbacea, Foudr.). Oblong- 
ovate, rather elongate, moderately convex, of a greenish-eneous or 
brassy colour, with a more or less distinct coppery reflection ; head 
small, vertex distinctly punctured, front with a smooth triangular space 
between the antenne ; thorax broader than long, nairowed in front, 
closely and rather distinctly punctured; elytra long, depressed on disc, 
with rather fine but distinct rows of punctures, interstices obsoletely 
punctured; legs reddish-testaceous, posterior femora nigro-eneous, 
anterior and intermediate femora often infuscate at base. L. 25-3 mm. 
On low plants, especially Cruciferze ; sometimes on poppies ; not uncommon and 
generally distributed throughout the greater part of the kingdom, 
P. instabilis, Foudr. (picipes, W.C., nec 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 
strie 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. cuprea, and have the anterior and intermediate femora more often 
infuscate. L. 23-27 mm.
