separately rounded at apex, finely punctured ; breast testaceous, abdomen 
black, scarcely punctured ; legs ferruginous or pitchy, posterior femora 
black. L. 13-2 mm. 
Chalky and sandy places; on Senecio jacobea, and also on Senecio vulgaris ; 
locally common in the Isle of Wight on Rew Down, Ventnor, and in other places ; 
Portsmouth district, Lumps Pond, Southsea; London district, local and not 
common, Folkestone, Bexley, Darenth, Mickleham, Southend (Champion, Power, and

red or brownish-red colour, with the head, breast, abdomen and apex of 
posterior femora black or pitchy ; antennze and legs (except posterior 
femora) lighter than the rest of the body, the former rather short ; 
thorax one and a half times as broad as long, smooth and shining, and 
finely punctured ; elytra rather distinctly, but very variably, punetured, 
the punctuation becoming obsolete towards apex ; they form a somewhat 
regular oval, and are obtusely rounded at apex ; on the exterior margin 
towards apex they are furnished with long whitish curved cilia, which 
are the chief distinguishing mark of the species ; immature specimens of 
this and the two following species are often almost entirely ferruginous. 
L. 2-23 mm. 
Male with the first joint of the anterior tarsi strongly and orbicularly 
dilated, and the fifth ventral segment impressed with a very obsolete line 
in the centre. 
On low plants, usually in marshy places; rare; Wicken Fen, in some numbers 
(Power and Crotch) ; Wallington, Northumberland (Power) ; Mr. Blatch records it 
from the Isle of Wight, Bristol, Gloucester, Bewdley, Sutton Park, and Knowle; it 
is probably often passed over. 
The 7. castanea of Stephens’ collection is really Z. luridus, and the 
specimens in the Britisa collection were referred, as a rule, to 7. brunnea 
prior to the appearance of Mr. Crotch’s catalogue.
