316 riiYTOPiiAGA. [P /union. 



In Dr. Power's collection there is a doubtful specimen of Pheedon, 

 which must be apparently referred to this species ; it has the elytra, 

 however, much more strongly punctured, and the punctuation of the 

 thorax also stronger and less even ; P. etulce, however, varies in this 

 respect in different specimens, and I think Dr. Power's specimen is an 

 extreme variety ; it may, however, prove to be a new species, but in any 

 case requires further confirmation, as it does not appear to agree with 

 any described European species. 



This species must not be confounded with Plagiodera armoracice, the 

 Clirysomela armnraciae of Linne and Fabricius ; the nomenclature of this 

 and the following species has given rise to much confusion, as the names 

 betulae and cochleanae have been applied to both ; Linnets Oh. betulte, 

 however, which was by Stephens and others supposed to be identical 

 with this species, is in reality Phyllodecta (Phratura) vulgatissima. 



P. cochleariae, F., nee Panz. (leevigatus, Duft. ; neglectus, Sahib.). 

 Very like the preceding, but smaller and narrower, and of a brighter 

 blue colour, sometimes with a strong greenish reflection ; the thorax is 

 less closely punctured on disc than at sides, and the elytra have the 

 humeral callosity very much less pronounced, and in many specimens 

 almost obsolete ; the punctured striae of the elytra are moderately strong, 

 and the interstices are extremely finely punctured; the anal segment of 

 the abdomen is only testaceous at the sides. L. 2^-3| mm. 



On Cruciferae ; also in marshy places at roots of grass, in moss, &c. ; common and 

 generally distributed throughout the greater part of the kingdom. 



P. concinnus, Steph. Very closely allied to the preceding, as a 

 rule, of a bright green or golden green colour, but sometimes coppery, 

 golden or greenish purple or blue ; it may be distinguished from the 

 foregoing species by having the upper surface more shining and the 

 interstices of the elytra finely but evidently punctured and more or less 

 rugose, and the striae less regular, the inner ones being finer and less 

 distinct ; the humeral callosity is a little more pronounced, but this is 

 not a very evident character; the antennae, which have the apex of the 

 scape, as a rule, more or less ferruginous in P. cochlearice, are, in this 

 species, entirely black. L. 2-3| mm. 



Salt marshes ; at roots of grass, in flood refuse, &c. ; very local ; rare in England ; 

 Gravesend (Marsh) ; Chatham (Walker) ; Southend (Stephens) ; Portsmouth district ; 

 recorded from Stoke Wood, Devon, in Piirfitt's catalogue ; Lancaster, in a marsh 

 (Chappell) ; Scotland, locally abundant in salt marshes on a cruciferous plant, Solway 

 and Clyde districts ; Mr. W. Leunon has sent it to me in plenty from a salt marsh 

 near Dumfries. 



PHYLLODECTA, Kirby. (Pkratora, Chevrolat.) 



This genus contains about twenty-five species, which are found chiefly 

 in Northern Asia and Europe ; one or two have occurred in Syria and
