On Nasturtium nnd other Crucifeno ; rare; Scotland, Solwny, Forth nod Clyde 

 dUtriot* j the m>eoie(i was introduced into the Hritiah list on the authority of one 

 specimen from Mr. Wollaston's collection, without locality, named by M. AUard. 



P. ochripeB, Curt, (excisa, Redt.). Oval, convex, shining black, 

 with the Imse of the antennae and the legs, except posterior femora 

 which are black, reddish-testaceous ; elytra with a longitudinal yellow 

 hand on each, enclosing a common oval blaok space on disc, their 

 external margins being very deeply emarginate in middle ; occasionally 

 the bands are entirely divided; antennae 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. 2|-2f mm. 



On ErysiiHum alliaria, Nasturtium amphibium, and Cardamina amira; local; 

 London district, common nnd generally distributed ; Wey bridge, Mickleham, Cater- 

 hara, Shirley, Walton, Forest Hill, Higbgite, Dulwich, St. Mary Cray, Sevenoaks, 

 Chatham, Dartford, Maidstone, &c. ; Kudham, Norfolk; Henley ; Hastings; Powder- 

 ham Marshes, Devon ; Ockbrook, Derbyshire (from specimens taken in which locality 

 it was first described by Curtis) ; Scarborough. 



P. ainuata, Steph. Oblong oval, rather depressed, black, shining, 

 with the base of the antennae and of the tibiae 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, antennae 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 antennae dilated. 



On Itnp'ianu* raphanistntm and other Cruciferm ; rare ; Chatham and Sheerness 

 (Walker) ; Quy Fen, Cambridge (Power) ; Wicken Fen (Champion) ; Oxford ; Hamp- 

 shire ; Swansea ; Sutton and Knowle, near Birmingham (Blatoh) ; Bretby Wood, 

 Repton (Garneys) ; York ; Liverpool. Ireland, Rathkurby, near Waterford (Power). 



P. tetrastig-ma, Com. In general appearance this species much 

 resembles P. oc.hripes, from which it may be at once known by its black 

 legs, which have the apex of the tibiae alone reddish ; from P. einuata 

 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 antennae 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 antenna? 

 are simple in botli sexes, and in the male the fifth ventral segment 

 of the abdomen is furnished with a rather deep triangular fovea which 

 almost reaches tho base. L. 2^-2^ mm.
