194 RHYNCHOPHORA. [ Eusomus. 
Africa, and Northern and Central Asia; one only occurs in Britain and 
it requires further confirmation before it can be regarded as really in- 
digenous; the members of the genus have somewhat the facies of 
Polydrusus, from which they may be known by the very convex ovate 
elytra, short scrobes and emarginate rostrum. 
EB. ovulum, Ill. About the size of Polydrusus sericeus, slender, black, 
clothed with yellowish-green, slightly metallic, round scales, which are 
sometimes more yellow on the alternate interstices of the elytra; antenne 
with the scape and base of the first joint of the funiculus ferruginous ; 
rostrum narrower than the head; eyes convex; scutellum wanting ; 
elytra oval with close-lying pubescence; anal segment of abdomen 
pubescent ; femora with a spiniform tooth, that on the posterior pair 
being very feeble, tarsi with the first joint elongate. L. 6-7} mm. 
On Achillea millefolium, among grass, &c.; extremely rare; “Taken by Mr. 
Edleston, at Grange” (Ent. Monthly Mag. viii. 83). The species has been recorded 
from Guestling, near Hastings, but Mr. Bennett, who recorded it, tells me that his 
specimen was wrongly named, and must be referred to another species; 2. ovulum, 
therefore, appears to require further confirmation as British. 
SCIAPHILUS, Steph. 
In this genus the head is narrower than the thorax, the eyes searcely 
prominent, the antenne long and slender, and the scrobes strongly 
deflexed ; the thorax is transverse and the elytra are oval; the whole 
upper surface is thickly covered with grey scales and strong outstanding 
scale-like setee, which are more evident on the elytra; the limits of the 
genus are not as yet properly defined ; about thirty species are enumer- 
ated in the Munich catalogue and about twenty in the European catalogue 
of Heyden, Reitterand Weise, but some of these most probably will have 
to be placed near Polydrusus ; only one species occurs in Britain. 
S. muricatus, F. (asperatus, Bonsd.), Black or fuscous-black, 
thickly covered with scales, which vary in colour froma dirty grey to 
yellowish-grey and sometimes show a slight metallic reflection ; antennee 
red with the first and second joints of funiculus elongate; rostrum glabrous 
at apex, with a V-shaped impression; scutellum very smal], but distinct ; 
thorax short, subeylindrical; elytra oval, with the alternate interstices 
slightly raised and a row of sete on each interstice, and with rather fine 
but distinct punctured strie, apex deflexed and acuminate; all the femora 
with a small sharp tooth. L. 4-6 mm. 
Male with the tibiz armed with a rather distinct hook. 
In woods and hedges ; by beating and sweeping ; often in moss ; somewhat local, 
but more or less common and generally distributed from the Midland districts south- 
wards ; rarer further north ; Manchester district, general but rare; Liverpool ; North- 
umberland and Durham district ; Scotland, occasional in moss and herbage, Solway, 
Tweed and Forth districts ; Ireland, Dublin, Waterford, Galway, Armagh, and 
probably general,
