266 PHYTOPHAGA. [ Ursodcicita. 



under-side is often dark, the remaining parts being lighter or darker 

 rufous or testaceous ; occasionally the whole body is dark with the 

 antennae and legs fuscous ; antenna? moderately long, reddish ; scutellum 

 smooth ; elytra more thickly and strongly punctured than thorax ; legs 

 moderately loug, testaceous. L. 4J-8 mm. 



On whitethorn blossom, Umbellifene, &c. ; rare ; Epping Forest ; Coleford, 

 Gloucestershire (Power) ; Matlock, Lovers' Walks, not uncommon ; I have found it 

 on the only two occasions I have collected in this locality, and Stephens records it 

 ns having been tken plentifully in the district; Ripon (Water-house) ; Yorkshire 

 (Blatch). 



Our specimens seem chiefly to belong to the var. chlorotica, Latr., 

 which has the under- side, and usually the upper side, entirely testaceous, 

 and the var. lineola, Lac., in which the under-side, vertex, suture, and 

 lateral margin of elytra are dark ; the var. gldbrata, F., which is entirely 

 black, with the antennae and legs fuscous, has not, as far as I know, 

 occurred in Britain. 



O. lineola, Panz., nee Lac. (ni<jriceps y Brit. Cat.). This species 

 much resembles the preceding, and, like it, is very variable in size and 

 colour ; it may, however, be known by the rather long pubescence of 

 its upper surface, which is more thickly punctured ; the thorax is longer, 

 and the under-side is more sparingly punctured and pubescent ; the 

 elytra in both this and the preceding species are sometimes broad and 

 rather flat, and sometimes narrow and convex ; the head and breast are 

 usually, but not always, black. L. 4-7 mm. 



On sallows, whitethorn blossom, &c. ; rare ; Ashtead (Blatch) ; Gravesend ; 

 Dtirenth ; New Forest (Power) ; Matlock ; very common in a wooded valley on the 

 Yorkshire Wolds on Spiraea ttlmaria in July (Allen Barker). 



V. liumeralis, Latr. Deep violaceous-blue, almost black, with two 

 red spots towards base of thorax and the shoulders of elytra reddish ; 

 the upper surface is sometimes immaculate. 



On the blossom and in the decaying wood of the whitethorn ; r<tre ; Ashtead 

 (Champion); Coombe Wood (1837) and Norwood (1887) (S. Stevens); Darenth 

 (Power) ; New Forest (Stephens, Power, &c.). 



DONACIINA. 



This tribe contains two genera, Donacia and Hcemonia, which are 

 chiefly found in cold and temperate countries ; they are characterized by 

 having the head prominent and somewhat narrowed behind the eyes, 

 the antennae long and slender and not very distant at base, the thorax 

 quadrate, much narrower than the elytra, which are punctured in 

 distinct rows, and the posterior coxae widely distant ; the first segment 

 of the abdomen is equal to the rest taken together; the tibiae are com- 

 pressed on their exterior margin, and arc more or less distinctly carinatc,
