Sitones. } RHYNCHOPHORA. 225 
conspicuous ; eyes flat ; rostrum with a plain central furrow; thorax 
about as long as broad, very closely punctured, with the sides almost 
straight and the anterior margin raised ; elytra with fine, but distinct, 
punctured striz, gradually narrowed for posterior third; antenne and 
legs red, club of the former, and the femora pitchy or black. L. 
4—4* mm. 
By sweeping vetches and other plants; occasionally in moss in winter; not uncom- 
mou and generally distributed in the London and southern districts ; common in the 
Midlands and as far north as Yorkshire; less common further north; Scotland, not 
common, Solway, Tweed and Forth districts; it is probably widely distributed in 
Ireland, 
As Mr. Rye observes (Ent. Monthly Mag. I. p. 230), the smaller size, 
more depressed eyes, and longitudinal bands of colour, distinguish this 
species from S. flavescens, with which it agrees in many points of struc- 
ture. Its depressed eyes, metallic hue, aud shorter, more robust, and 
less parallel elytra separate it from S. lineatus,; and the very prominent 
eyes of S. tilalis at once distinguish the latter insect, which resembles 
in markings the greenish-grey specimens of S. suturalis: S. suturalis, 
when quite fresh, is sometimes a very brilliant insect, of a coppery red 
colour, and is the prettiest of all our species, but it is very easily abraded 
and not often seen in its best condition. 
S. ononidis, Sharp (guttulatus, Chevr.). Closely allied to the 
preceding species, but differing in being rather larger, less cylindrical, 
not so convex, and clothed with scarcely metallic scales ; its eyes, more- 
over, are a little less prominent, not so circular in outline, but more 
elliptical ; the elytra are not so strongly punctate-striate and the inter- 
stices are quite flat, instead of being slightly convex; underside clothed 
with greyish scales. L. 4-43 mm. 
On Ononis spinosa; very local; first recorded by Dr. Power from Herne Bay in 
September, 1865, and subsequently by Dr. Power and Mr Champion; Whitstable 
(Champion) ; St. Lawrence, Isle of Wight (one specimen taken by myself in the early 
spring of 1882); Heysham and Lancashire (Reston); Dr. Power had apparently 
taken the species at Herne Bay in 1854, and it was most probably mixed with his 
suturalis. 
S. lineatus, L. Black, upperside clothed with fuscous scales, 
which are lighter on three lines on thorax, and on the elytra are more or 
less lineated, but the latter are very variable, and sometimes quite uni- 
colorous ; head with a central furrow, eyes moderately prominent, an- 
tenn rather long and slender, red or ferruginous ; thorax transverse, 
with the sides moderately but evidently rounded, anterior margin some- 
what raised, finely and very closely, but rather distinctly punctured ; 
elytra long and parallel, with rather fine, but distinct, punctured strie ; 
legs moderately long, femora dark, tibiee and tarsi red or ferruginous ; 
underside thickly clothed with ashy or greyish scales. L. 4-5 mm. 
Male with the anterior tibis curved, and armed with a small hook,
