30 4 RHYNCHOPHORA, [ Sidinia. 
yellowish brown bands which meet, or almost meet, in front; elytra 
with a large common spot of the same colour behind scutellum, which 
reaches at least to middle, and is usually contracted in middle and more 
or less dumb-bell shaped; striew fine, concealed by the scales; legs 
Squamose or pubescent. L. 2-25 mm. 
Sandy places near the coast; very local, but sometimes in great abundance where 
it occurs; on and at the roots of Arenaria maritima; Sheerness; Harwich ; 
Hastings district ; Portsmouth district, Southsea ; New Forest ; Lymington Salterns 
Cin profusion at the roots of Arenaria at the end of August in hot sun after a thunder 
shower) ; Isle of Wight, Black Gang Chine, Chale, Ventnor; Chesil Beach ; Devon; 
it is sometimes found at the roots of grass in September and October. 
S. primitus, Herbst. Extremely lke a small specimen of the 
preceding, which it resembles in the general colour and in the mark- 
ings of the thorax and the elytra ; it may, however, be known by its 
narrower and considerably smaller form, and by having the whole of 
the antenne and rostrum black or pitchy-black ; if we compare ordinary 
specimens of both species, the scales of S. primitus appear to be darker 
and more coppery, whereas those of S. arenarie are of a more greyishi- 
yellow tint. L. 13-2 mm. 
Sandy places; by sweeping herbage; often found in sand pits and in moss; very 
local; London district, not uncommon, Norwood, Shirley, Esher, Mickleham, 
Birch Wood, Horsell, Caterham, Wimbledon, Ashtead, Chatham, Maidstone, Sheer- 
ness, Dartford; Asbwicken, Cambridge; Dover; Hastings district; Southsea; 
Shirley Warren, Southampton ; Glanvilles Wootton; Yardley, near Birmingham 
( Blatch). 
S. sodalis, Germ. (cretaceus, Bris. ; statices, Moncreaft). Oblong- 
ovate, black or dark ferruginous, densely and entirely clothed, when 
fresh, with short and rather broad scales which are greyish-brown with 
a slight reddish tinge, especially on thorax, and with an indistinct 
sutural and a still more indistinct humeral line composed of slaty-grey 
scales, which are also scattered about the elytra; the scutellum is 
greyish-white and the legs, rostrum and antenne more or less ferru- 
ginous ; underside with whitish-grey scales; rostrum moderately long, 
curved ; thorax transverse, with the sides rounded, constricted before 
apex ; elytra a little broader than base of thorax, with fine punctured 
striae (which are more or less hidden by the scales), interstices flat, with 
rows of short white sete. L, 2-25 mm. 
In flowers of Armeria vulgaris ; very local; taken in plenty at the Island of Portsea 
by Mr. Moncreaff, who discovered it in the summer of 1866. 
GYMNETRINA. 
The Gymnetrina, like the Cionina, may be distinguished by having the 
funiculus of the antenne composed of five joints; from the latter tribe 
they may be known by the formation of the ventral segments of the 
abdomen and the fact that the pygidium is more or less exposed ;
