be known by the absence of erect setae, 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 striae on the elytra are fine but dis- 

 tinct ; legs and antennae red or ferruginous, club of the latter and the 

 femora more or less dusky. L. 34 mm. 



On clover, trefoil, vetch, &c. ; common in the London district and the south of 

 England; less common further north, and rather rare, as far as mv 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 Twe^d 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 tlie 

 front much less deeply excavated, the thorax closely and minutely punc- 

 tured, the elytra elongate, Avith 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 ddated and 

 rounded ; elytra elongate, with the sides nearly straight, and with rather 

 deep punctured striae, maculated at shoulders and scutellum, interstices 

 indistinctly variegated with fuscous and ashy scales ; abraded specimens 

 often occur with scanty silvery-grey scales; underside thickly scaled; 

 legs black, with the base and apex of the femora and the tibiae and tarsi 

 testaceous. L. 4 t^ mm. 



On the melilot trefoil (Melilotiis qfficinalis); very local, but occasionally found in 

 numbers ; Chatham ; Reigate; Plumstead ; formerly at Hammersmith ; Ryde, Isle of 

 Wight ; Yorkshire ; Northumberland and Durham district, rare, So\ith 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 ; antennae 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 striae; tibiae red. L. 5-5^ mm.
