of the Genera Homopheta, Asphera, and Oe¢edionychis.

(Plates XIV. & XV.*) 
In the ‘ Proceedings’ for 1894 (p. 609) I have given the descrip- 
tions of many species belonging to the group of bladder-clawed 
Halticine, which until then were simply Catalogue names as 
published by Clark. The number of further species which I have 
received since enables me to publish here a considerable addition 
to my former paper; where Clark’s names have been retained for the 
same species I have stated this, but by far the greater portion of 
my species were not known to Clark. The genera Oedionychis and 
Asphera as at present understood almost rival in species the 
Galerucid genus Diabrotica, and it is frequently very doubtful to 
which of the two genera a species should be referred. Von 
Harold has tried to point out the differences between Oedionychis, 
Asphera, and the allied genera (Coleopterol. Hefte, xv. p. 91), and 
lays the principal stress on the more or less elongate first jomt of 
the posterior tarsi in Asphera in contradistinction to the corre- 
sponding very short joint in Oedionychis, which in most. cases 
holds good, but in many instances there are intermediate degrees 
as well as in the more or less inflated claws, so that it is uncertain 
to which genus these species should be referred; these are, 
however, rather exceptional, and vy. Harold’s definition must be 
accepted for want of a better one. All the species described here 
are contained in my collection. 
HOMOPH@TA CLAVAREAUT, Sp. 0. 
Black, a frontal spot and the clypeus flavous; thorax fulvous, 
impunctate ; elytra nearly impunctate, fulvous, a broad transverse 
band at the base and another narrower one below the middle, 
black. 
Length 9 millim, 
Head black, very shining, with some punctures near the eyes 
the latter widely separated, with a flavous transverse spot at the 
intermediate space, frontal elevations narrow, likewise flavous as 
well as the clypeus; antenne extending beyond the middle of the 
elytra, black, the first joint fulvous below, third and fourth joints 
equal; thorax twice as broad as long, the sides feebly rounded, 
with narrow thickened margins, the anterior angles strongly pro- 
duced and thickened, the surface fulvous, impunctate, rather 
convex; scutellum black; elytra with narrow, reflexed margins, 
microscopically finely punctured, fulvous, with a rather broad 
basal band occupying about one-fourth of the length of the elytra, 
its posterior edge oblique, widest at the suture, another narrower
