363 PHYTOPHAGA. [Phylint retd. 



In damp places, by sweeping Crucifene, especially Nasturtium ojfficinale and 

 Cardamiite amara ; local ; Highpnte, Horsell, Aylsham, Reigtite, Maidstone ; 

 Windsor; Ditchingham, Suffolk; Hastings; Bretby Wood, Repton; Withington, 

 Cheshire ; Manchester and Liverpool district ; Northumberland and Durham district ; 

 Scotland, rtire, Solway and 'fay districts ; Ireland, Armagh (Johnson). 



P. ezclamationis, Thunb. (brassiere, F. ; quadripustulata, Payk.). 

 A small, short, convex species, which resembles a small Aphthona or 

 Thyamis rather than a Phyllotreta ; oval, convex, black, shining, with 

 two yellow patches on each elytron, which are variable in size and are 

 rarely united by a narrower or broader yellow line ; antennae testaceous, 

 more or less fuscous towards apex ; thorax convex, with sides strongly 

 rounded, closely and rather finely punctured; elytra very convex, 

 much broader than the base of thorax, thickly and somewhat strongly 

 punctured ; legs pitchy black, or black, with the tibiae and tarsi more 

 or less reddish ; the general colour of the legs, however, is variable. L. 

 li-li mm. 



Marshy places ; on Crncifera ; local, but not uncommon in many districts, and 

 widely distributed from the Midlands southwards ; rarer further north ; Northumber- 

 land and Durham district, not common, but baa been taken in several localities; 

 Scotland, very rare, Solway district ; Ireland, near Dublin. 



APHTHONA, Chevrolat.* 



In this genus the forehead is impunctate and furnished with rather 

 distinct lines and tubercles ; the anterior coxal cavities are open behind ; 

 the thorax has no basal furrow ; the pygidium is covered, and is 

 channelled on its upper surface ; the first joint of the posterior tarsi is 

 three times shorter than the tibia, and the spur of the posterior tibiae 

 is inserted at the outer side of the apical edge ; the species vary very 

 much in colour and considerably in size ; about one hundred and fifteen 

 are at present known, which are very widely distributed over the 

 greater part of the world, and range from Kamtschatka to the Cape 

 of Good Hope, South America, and the Australian region ; a considerable 

 number have recently been described from Central America, and it is 

 probable that the genus will ultimately prove to be a very large 

 one in point of numbers ; about forty species occur in Europe, of 

 which eight are found in Britain ; these may be distinguished as 

 follows : 



I. Upper surface mostly testaceous or pale yellow. 



i. Head testaceous, or ferruginous 5 size largi-r ... A. LOTESCBNS, Gyll. 

 ii. Head black, site smaller A. NIGIUOEPS, Sedt. 



II. Upper surface dark, greenish, bluish, purplish or 

 nigro-seneous. 



* Just after the sheet containing the table of genera (p. 333) had gone to press, 

 I discovered an error affecting this genus: on page 333, last line, " APHTHONA, 

 Chevr." should be erased, and inserted on pnge 334, line 9, immediately under 

 PHTLT.OTKETA, Foudr., at the end of paragraph b*.
