Psylliodes.] PHYTOPHAGA, 393 
base testaceous, legs pitchy with the posterior femora cyaneous ; head 
finely punctured, antenne comparatively short and stout ; thorax twice 
as broad as long, narrowed in front, finely punctured, the punctuation 
consisting of larger and smaller punctures intermingled ; elytra with 
joderate rows of punctures, interstices finely, but distinctly, punctured 7 
in this and all the following species the posterior tibiae are short and 
considerably arched on their under-side, and the posterior femora are 
very broad. L. 3-3! mm. 
Chalky places; on Solanum duleamara ; local, but not uncommon where it occurs; 
Darenth, Esher, Croydon, Caterham, Mickleham, Westerham, Maidstone, Dartford, 
Chatham ; Hastings ; Hayling Island ; New Forest; Glanvilles Wootton; Horning 
Fen, Norfolk ; Wicken Fen, Cambridge ; Ireland, near Waterford (Power). 
P. chalcomera, Ill. (hyoscyami var., Weise). Oblong-ovate, 
subelliptical, of a deep blue colour above, antenne pitchy black, with 
the base reddish-testaceous ; legs red or ferruginous with the posterior 
femora nigro-eneous; thorax with double punctuation ; elytra with 
rather strong rows of punctures, interstices finely but distinetly punc- 
tured and somewhat rugose ; from the preceding species it may easily 
be known by its red legs, and from P. napt by its larger size and stronger 
sculpture ; it is considered by Weise (l.c. p. 821) to be merely a variety 
of P. hyoscyamz, and it certainly only differs from that species in a few 
slight particulars. L. 3-4 mm. 
On Carduus nutans and Circea, also on Nasturtium officinale ; local; London dis- 
trict, not uncommon and widely distributed ; Hastings ; Folkestone ; Eastbourne ; 
Brighton ; Hunstanton, Norfolk ; Yorkshire; Scotland, Tweed and Forth districts ; 
it probably occurs in many intervening localities ; Ireland, Armagh. 
P. hyoscyami, L. Very like the preceding, but of a bronze-green or 
slightly coppery colour; under-side nigro-zneous ; antennex black with base 
reddish-yellow ; legs reddish-yellow with posterior femora dark ; thorax 
with the punctures smaller but thicker and closer than in P. chalcomera ; 
the punctured striz of the elytra are also, as a rule, but apparently not 
always, deeper. L. 3-4 mm. 
On Hyoscyamus niger (Common Henbane) ; very rare as a rule, although oceasion- 
ally found in some numbers ; Shirley, near Croydon (Ry e); Merton, Surrey (Power); 
Manchester district, in some numbers (B. Cooke); Seotland, Forth district, “ Dal- 
meny, Mr. Greville,” Murray’s Cat. ; Ireland, Firhouse near Dublin. 
P. luteola, Miiller (propinguus, Redt.; pallida, Steph.). Elongate 
ovate, entirely testaceous or ferrugino-testaceous, with the labrum, the 
antenne towards apex, the breast and abdomen, and the posterior femora 
in part, ferruginous or infuscate; head obsoletely punctured; thorax 
transverse, rather thiekly and very finely punctured : elytra comparatively 
narrow, depressed on disc, with regular rows of distinct but comparatively 
fine punctures, which are less pronounced at apex; the species some- 
what resembles P. afinis, but may at once be known by its narrow and 
more elongate form, testaceous head and generally lighter colour, and the 
much finer punctuation, L, 21-23 mm,
