Mr. J.S. Baly on the Classification of the Eumolpide. 441 
being thickened and compressed. I only know two species, both from 
Port Natal; the second, described formerly by myself in this Journal 
(antea, p. 220) as a Bromius, I dedicated to H. Bohemann. 
Genus Acroruinium, Marshall. 
Recens. Corynod., Proc. Linn. Soc. 1864. 
Body oblong, convex, metallic, clothed with suberect hairs. Head per- 
pendicular, deeply buried in the thorax; antenne subfiliform, five 
upper joints slightly compressed and thickened, basal joint short, in- 
crassate, second nearly equal in length to the first, four following joints 
nearly equal, slender, each rather longer than the first ; eyes with their 
inner edge very slightly sinuate. Thorax subcylindrical above, lateral 
margin distinct, entire, surface coarsely punctured. Elytra broader 
than the thorax, convex, coarsely punctured, covered with suberect 
hairs, which are rather more scattered than in Bromius and the other 
allied genera. Legs robust; thighs produced into an indistinct angle 
beneath ; intermediate tébie obsoletely notched near the apex; the 
three lower joints of all the ¢arsi of equal breadth, second joint trian- 
gular, third narrowed at the base, semiovate ; wngurculr appendiculated. 
Prosternum united in a single piece with its episterna. 
Type, Acrothinium Gaschkevitchii, Motsch. Etud. Entom. 1860, p. 23. 
The only species hitherto known as belonging to the genus is 
found native in Northern China and Japan, where it appears to be 
common. Both the Rey. T. Marshall and Motschulsky, in their dia- 
gnoses, have omitted to notice the pubescence on the upper surface 
of the body: this character, together with the absence of the sutural 
grooves between the prosternum and episterna, removes the genus 
from the Corynodine to the present subfamily. Motschulsky has 
described the insect as belonging to Chrysochus, a genus with which 
it has no affinity. 
Genus Lorna, Baly. 
Body subelongate, parallel, subcylindrical, non-metallic, clothed with 
coarse suberect hairs. Head deeply buried in the thorax, perpen- 
dicular ; antenne subfiliform, the five upper joints slightly thickened 
and compressed, first joint incrassate, second short, third, fourth, fifth, 
and sixth slender, equal, each rather longer than the first ; eyes entire. 
Thorax transversely convex, subglobose on the disk ; lateral border dis- 
tinct, entire. Elytra broader than the thorax, subcylindrical, coarsely 
punctured. Legs robust; thighs simple; external surface of inter- 
mediate fb¢e not notched; basal joint of tarsus narrower than the 
second, the latter triangular, the third broad at the base, transverse, 
closely articulated with the second, the two conjointly cordate ; wn-
