Mr. G. Lewis on the Japanese Rhipidoceride. ga 
V.—Note on the Japanese Rhipidoceride: a new Genus 
and Species. By G. Lewis, F.L.S. 
THERE are only two species of this family known to me from 
Japan, and of these one is a species of Sandalus, described 
and roughly figured as S. segnis, Lew., Ent. xx. p. 315, 
1887, and for the other it seems necessary to establish a new 
genus. 
HORATOCERA (visibilis, cornuta), gen. nov. 
The characters of this genus are in the greater part the 
same as those of Callirrhipis, the differences chiefly being 
that the antenne are inserted in the head much wider apart, 
and the joints 3 to 10 are longer and coequal and about a 
quarter to a third of the lengtlt of the appendage they bear ; 
the eyes are more prominent, smaller, and much more clearly 
faceted; the scutellum much longer than broad; the pro- 
sternal process is shortened posteriorly, and does not reach 
beyond a point which corresponds to the middle of the coxe ; 
the inner process of the claws is much less conspicuous. 
Type H. niponica (the figure gives the outline of the 
species and the claw of the hinder tarsus). 
I possess a second species from the Andaman Islands. 
In Callirrhipis the prosternal process is long and narrow 
posteriorly and overlaps the anterior part of the mesosternum ; 
in some of the species, notably C. fasciatus, Waterh., it is 
very long, but in the type of the genus, C. Dejean?, Latr., it 
is of moderate length.
