EUMOLPINA. 
This important tribe contains upwards of one hundred and fifty genera, 
which, however, for the most part contain only a small or comparatively 
small number of species; they are chiefly found in tropical countries, 
only eleven genera and twenty-six species occurring in Europe; one 
only is found in Britain, Lamprosoma (Oomorphus) concolor, which in 
the Munich catalogue is classed with the genus Lycnophaés under a 
separate tribe Lamprosomina ; the Eumolpina are chiefly distinguished 
by having the clypeus emarginate, the antenne broadly distant at base 
and inserted on the forehead behind the base of the mandibles, the 
anterior cox round, and the tarsi with the penultimate joint plainly 
bilobed. 
LAMPROSOMA, Kirby. (Oomorphus, Curtis.) 
This genus contains, as far as is at present known, about one hundred 
and twenty species, of which no less than thirty-nine have been described 
since the publication of the Munich catalogue; the majority of the 
species are found in Central America and Brazil, Cayenne, Bolivia, &e., 
but a few have been described from North America, Cuba, and other 
neighbouring localities; only one species occurs in Europe, which was 
described by Curtis; its position for some time was much disputed ; 
Stephens placed it near Simplocaria with the Byrrhide; it is a small 
and very shining black insect, and at first sight strongly resembles a 
Phedon ; the head is small and sunk in the thorax, and the mandibles 
are short and stout; the antenne are received in furrows on the pro- 
sternum, aud are short; the mesosternum is hidden; the legs are stout, 
with the tarsi dilated, and the claws are thin and small. 
XZ. concolor, Sturm. Ovate, very convex, shining black with a 
slight bronze reflection; head exceelingly finely wrinkled, antenne 
short with joints 7, 9, 10, and 11 thickened, the 8th being smaller, 
2nd joint red ; thorax transverse, much narrowed in front, rather thickly 
and finely punetured ; scutellum small; elytra with rather fine rows of 
larger punctures, interstices broad and very finely and diffusely punctured; 
legs black, claws very small; the punctuation is rather stronger in certain 
larger specimens, which are perhaps females. L. 2-3 mm.
