144 SERRICORNIA, [Rhagonyera, 
apex, female with the last ventral segment very slightly sinuate on each 
side at apex. 
On flowers, by sweeping grass, &c.; local; London district, not common, Chatham, 
Leith Hill, Esher, Woking, Birdbrook, Aylsham, Tonbridge, ‘Tilgate Forest ; 
Hastings; New Forest; Glanvilles Wootton; Devon; Dean Forest; Swansea ; 
Cannock Chase; Trench Woods; Robins Wood, Repton; Knutsford, Cheshire ; 
Leyburn, Yorkshire ; Bowdon, Manchester; not recorded from the Northumberland 
and Durham district, but probably occurs; Scotland, local, Solway, Tay, Dee, and 
Moray districts; Ireland, near Dublin, Armagh, Belfast, Larne, &c. 
R. limbata, Thoms. (fesfaceus, var., auct.). Very like the pre- 
ceding, but easily known by having the femora more or less broadly 
dark, and the whole of the margins of the thorax testaceous ; the colour, 
however, is variable to a certain extent, and would not be enough to 
constitute the insect a separate species; Thomson, however, has 
pointed out that the sexual characters are different, the male having 
the seventh ventral segment depressed and subtrunecate at apex, and 
produced into a tooth on each side, and the female having the last 
ventral segment slightly emarginate at apex. L. 33-4 mm. 
By sweeping flowers, grass, &c. ; much commoner than the preceding, and gene- 
rally distributed throughout the country ; it is extremely abundant in the Midlands, 
R. pallida, F. (pallipes, F.). A narrow, elongate, and graceful 
species; head, thorax, and under-side black, elytra of a light testaceous 
colour ; head finely punctured, considerably different in shape in the 
sexes, antenne long and slender; thorax about as long as, or a little 
longer than, broad, extremely finely punctured, narrowed in front, with 
an obsolete central channel ; scutellum black ; elytra with long aud 
scanty pubescence, sculpture rugose and shallow; legs clear yellow. 
L. 5-7 mm. 
Male with the head broader than in female, and the eyes very large 
and prominent, and the third joint of the antenne longer in proportion 
to the second; the antennz are much longer in the former sex than in 
the latter. 
By sweeping and beating in woods; common and widely distributed throughout 
England and Wales and the greater part of Scotland; Ireland, Armagh, Belfast, and 
Dublin, and probably common. 
R. elongata, Fall. (paludosa, Redt., nec Fall.). Flongate, entirely 
black, with the base of the antennz and tibie, and, as a rule, the apex 
of femora and more or less of the tarsi testaceous or obscurely tes- 
taceous; head varying in the sexes, antennie longer in male than in 
female ; thorax subquadrate, slightly narrowed in front, with a more or 
less obsolete depression or channel in middle of disc, posterior angles 
well marked; elytra broader than thorax, with rather long and scanty 
greyish pubescence, rather closely and rugosely punctured, with traces 
of raised lines; under-side black, with margins of segments often a little 
lighter. L. 5-6 mm,
