be known by the absence of erect sete, and by the colour of the elytra, 
which are clothed with dark brown scales on disc, and light scales to- 
wards sides, which form a conspicuous patch at each shoulder, and 
cause them to appear more or less lineated towards sides, the disc being 
always dark ; there are also three lighter lines, often more or less obso- 
lete, on the thorax; the colour, however, is variable and the insect is 
sometimes greyish ; the shoulders are strongly marked ; the thorax is 
finely punctured, and the punctured striz on the elytra are fine but dis- 
tinct ; legs and antennz red or ferruginous, club of the latter and the 
femora more or less dusky. L. 38-4 mm. 
On clover, trefoil, vetch, &e.; common in the London district and the south of 
England; less common further north, and rather rare, as far as my experience goes, 
in the Midlands, Knowle, near Birmingham, Repton, &c.; Filey, Yorkshire (com- 
mon) ; Northumberland and Durham district, rather uncommon but widely distri- 
buted ; Scotland, rare, Solway and Twecd districts ; it has not apparently occurred 
in Ireland. 
S. meliloti, Walt. Most nearly allied to the preceding species, 
the head, thorax, and depressed eyes being very similar, but with the 
tront much less deeply excavated, the thorax closely and minutely punc- 
tured, the elytra elongate, with the shoulders subrectangular and 
rounded, and without the conspicuous light patch; the colour is black, 
clothed more or less thickly with cinereous and silver-grey, or coppery 
and fuscous scales: head narrow, closely punctured, front flat, with a 
deeply impressed longitudinal line ; eyes depressed and comparatively 
small; thorax as broad as long, with the sides moderately dilated and 
rounded ; elytra elongate, with the sides nearly straight, and with rather 
deep punctured striz, maculated at shoulders and scutellum, interstices 
indistinetly variegated with fuscous and ashy scales ; abraded specimens 
eften occur with scanty silvery-grey scales; underside thickly scaled; 
legs black, with the base and apex of the femora and the tibie and tarsi 
testaceous, L. 4-45 mm. 
On the melilot trefoil (Melilotus officinalis); very local, but occasionally found in 
numbers ; Chatham; Reigate; Plumstead ; formerly at Hammersmith ; Ryde, Isle of 
Wight ; Yorkshire; Northumberland and Durham district, rare, South Shields and 
near Hartley. 
S. flavescens, Marsh. Black, thickly clothed with brownish or 
yellowish-brown scales, which are very little variegated, the elytra at 
most being furnished with a few very small and obscure grey and black 
dots ; head with a central furrow; antenne red with the club pitchy, 
or with the base only red ; thorax about as long as broad, very finely 
punctured, with the sides almost straight, and with three obscure 
lighter longitudinal bands; elytra with the shoulders well marked, not 
setose, with fine punctured strie; tibie red. L, 5-54 mm. 
Male with the fifth ventral segment of abdomen subtruncate at 
apex.
