130 Mr. Walter F. H. Blandford on the 
stronger, suture longitudinally impressed before apex ; posterior 
margin gently rounded and fringed with aureous pubescence 
which conceals the very shortly produced apical angles ; 
posterior impression narrow, sublinear, concave, hidden by 
apical margin. Underside ferruginous, with scanty pubescence, 
abdomen concave, not strongly punctured, sides of 2nd and 4th 
segments scarcely produced, last segment with a large deep 
transversely oval impression, bordered in front by a fringe of 
aureous hairs, and reaching the prominent apical margin. Anterior 
tibix with five carine, and indistinct traces of others at base ; 
intermediate tibiz with a single carina on anterior surface ; 
posterior tibiz dilated, with outer border convex, and apex 
produced into two serrate lobes on either side of tarsal articu- 
lation, densely ciliate, with yellowish hairs. Posterior coxe with 
a prominent free margin to inner and apical borders, which with 
the posterior margin of the trochanter is sharply serrate. 
I cannot refer this fine and distinct species to any 
of Chapuis’ groups. I therefore propose for it a distinct 
group, Crossotarst mutici, characterized in the female 
by the gently declivous elytra, without elevated inter- 
stices or conspicuously produced apical angles, and with 
a narrow deep posterior impression, in which it 
approaches C. minav, Walk. The structure of the 
posterior tibia, and the abdomen, together with the 
absence of a distinct scutellum, are also characteristic 
features. The specimen is undoubtedly a female—in 
the conventional sense. 
Crossotarsus niponicus, sp. 1.

infuscatis ; prothorace subquadrato, irregulariter punctato, punctis 
ad basim haud profundioribus; elytris lineato-punctatis, stria 
suturali per totum, ceteris modo ad basim apicemque impressis, 
apice convexe declivi, angulis externis productis, depressione 
angusta ; abdominis segmento primo spinula obliqua armato.
