ape, claws appendiculate, prosternum broad, subquadrate, ils base 
truncale, the anterior margin of the thoracic episternum concave. 
The species for which I am obliged to establish the present genus, 
has entirely the facies of a Colasposoma but the appendiculate, not 
bifid claws forbid the reception of the insect in that genus, the 
anterior legs in the male resemble much those of a species of 
Sybriacus although they are not so strongly incrassate as in that 
genus; Sybriacosoma will find its place amongst the Zphimeince. 
Sybriacosoma ornata Jacoby (Novit. Coleopt. 1895, p. 3). 
Piceous, antenncæ and legs fulvous, the seventh and eighth and the 
terminal joint of the former, black, head and thorax cupreous, closely 
punctured, elytra closely semipunctate-striute, purplish, the sutural 
and lateral margin, a transverse band below the base and a stripe at 
the posterior portion, aureous. 
Mas. The anterior femora dilated, the tibiæ curved and widened at 
the apex. 
Fém. The shoulders, acutely raised, the sides with an angulate costa 
and a small tubercle. 
Var. À. Legs piceous. 
Var. B. Thorax and elytra metallic blue. 
Length : 2 lines. 
Head distinetly and rather closely punctured, the vertex more 
strigosely punctate, aureous as well as the sides to a greater or 
smaller degree, the middle portion cupreous or purplish, the 
epistome not separated from the face, labrum and palpi fulvous, 
eyes very widely separated, antennæ filiform, the apical joint 
thickened and elongate-ovate, the second joint one half shorter than 
the first, both thickened, third joint elongate, twice as long as the 
second one, the lower six fulvous, the following two joints and the 
apical one, piceous. 
Thorax twice and a half broader than long, the sides nearly 
straight, slightly narrowed in front, surface transversely convex, 
very closely and finely punctured, purplish-cupreous, the margins 
narrowly metallic aureous, scutellum not longer than broad, with 
a few fine punctures, metallic green, elytra not wider at the base 
than the thorax, with a slight transverse depression below the base, 
this depression, in shape of a narrow transverse band, a longitudi-
