S. hemisphericus, L. Broad oval, suborbicular, somewhat nar- 
rowed in front and behind, black, or pitchy black, shining, rather convex 
but depressed on disc, clothed with thin and scanty greyish pubescence ; 
head moderately large, antenne dark, with base yellow, second joint as 
broad as first and not much shorter; thorax very short, narrowed in 
front, very finely punctured, with sides often yellowish, base sinuate ; 
elytra rather strongly and closely punctured ; legs more or less obscurely 
testaceous, with femora darker ; tibiae with very long spurs. L. 23-

Male with the last ventral segment of abdomen slightly emarginate at

S. orbicularis, Panz. (pailescens, Steph.). Closely allied to the 
preceding species, of which it has been by some authors considered a 
variety ; apart, however, from its colour, which is pale fuscous or 
fusco-testaceous, it may be known by the closer and finer punctuation of 
the elytra, and rather thicker pubescence ; the interstices between the 
punctures of the elytra, moreover, are slightly rugose. L. 23-35 mm.

EUBRIA, Germar. 
The genus Eubria, which by some authors has been regarded as 
forming a separate tribe Eubriina, or even family Eubriade, is easily 
distinguished by having the antenne serrate from the third joint inclu- 
sive, the second joint being minute, and by the strong engraved lines on 
the elytra; only one species is known, which occurs very rarely in 
Britain, and is uncommon on the Continent; £. marchantie, Duv., is 
now generally regarded as a variety of EL. palustris. 
E. palustris, Germ. Orbicular, convex, black or dark pitchy brown, 
rather shining, extremely closely and finely punctured; head rather 
small, deeply sunk in thorax, eyes moderately prominent, antennx rather 
long, pitchy with base lighter; thorax double as broad as long, narrowed 
in front, posterior margin very slightly sinuate ; scutellum large ; elytra 
broadest behind middle, very finely pubescent, with five deeply engraved 
lines on each, the first of which reaches from base along seutellum and
