Phyllotreta.| PHYTOPHAGA. 
On Nasturtium and other Crucifere ; rare ; Scotland, Solway, Forth and Clyde 
districts ; the species was introduced into the British list on the authority of one 
specimen from Mr. Wollaston’s collection, without locality, named by M. Allard. 
P. ochripes, Curt. (excisa, Redt.). Oval, convex, shining black, 
with the base of the antenne and the legs, except posterior femora 
which are black, reddish-testaceous ; elytra with a longitudinal yellow 
band on each, enclosing a common oval black Space on disc, their 
external margins being very deeply emarginate in middle; occasionally 
the bands are entirely divided; antenna stout, with the fifth joint 
much elongate, and strongly dilated in the male ; thorax convex, with 
sides rounded, rather strongly punctured, especially at sides; elytra 
somewhat strongly punctured in front, and much more finely behind ; 
legs somewhat variable in colour, usually as above, but sometimes more 
or less infuscate. L, 24-22 mm. 
On Erysimum alliaria, Nasturtium amphibium, and Cardamine amara; local ; 
London district, common and generally distributed ; Weybridge, Mickleham, Cater- 
ham, Shirley, Walton, Forest Hill, Highgate, Dulwich, St. Mary Cray, Sevenoaks, 
Chatham, Dartford, Maidstone, &e. ; Rudham, Norfolk ; Henley ; Hastings; Powder- 
ham Marshes, Devon ; Ockbrook, Derbyshire (from specimens taken in which locality 
it was first described by Curtis) ; Scarborough. 
P. sinuata, Steph. Oblong oval, rather depressed, black, shining, 
with the base of the antenne and of the tibix reddish, each elytron 
* with a longitudinal yellow band; these bands are abruptly curved in- 
wards towards the suture at base and apex, and enclose a common 
rectangular black space, a point which will at once distinguish the 
species ; the outer margin of the bands is strongly emarginate in middle; 
head and thorax closely and subrugosely punctured, antenne rather 
short and stout; elytra distinctly punctured towards base, obsoletely at 
apex. L. 2-2! mm. 
Male with the fourth and fifth joints of the antenne dilated. 
On Raphanus raphanistrum and other Crucifere ; rare; Chatham and Sheerness 
(Walker) ; Quy Fen, Cambridge (Power) ; Wicken Fen (Champion) ; Oxford ; Hamp- 
shire ; Swansea; Sutton and Knowle, near Birmingham (Blateh) ; Bretby Wood, 
Repton (Garneys) ; York ; Liverpool. Ireland, Rathkurby, near Waterford (Power). 
P. tetrastigma, Com. In general appearance this species much 
resembles P. ochripes, from which it may be at once known by its black 
legs, which have the apex of the tibie alone reddish ; from P. sinwata 
it may be distinguished by its larger size, and by not having the yellow 
bands on the elytra abruptly bent inward at base and apex, the space 
between them being elongate oval ; occasionally the bands are divided, 
forming four patches; the antenne are rather long, and are pitchy or 
ferruginous at base ; the thorax is not very closely and rather finely 
punctured, and the elytra are rather strongly and not closely punctured 
at base, the punctuation becoming obsolete towards apex; the antenne 
are simple in both sexes, and in the male the fifth ventral segment 
of the abdomen is furnished with a rather deep triangular fovea which 
almost reaches the base. L, 21-23 mm.
