very positively as to its structure. I am by no means sure that this is really the 
species Motschoulsky intended to describe as L. basalis.

169. Laccophilus chinensis, Boh., M.C.—Ovalis, subdepressus, sat latus, perni- 
tidus, rufo-testaceus, elytris fere equaliter fusco-irroratis, fascia sub-basali con- 
spicua pallida. Long. 33, lat. 2 m.m. 
In this species the fuscous marks on the elytra can scarcely be traced as being 
flexuous lines, but appear to be small sinuous dark marks, separated by yellow 
ones of about the same size : the sides, however, and a conspicuous fascia near the 
base are yellow. The male has the front and middle tarsi but little dilated ; its 
apical ventral segment has the hind margin a good deal oblique on each side, but 
very little sinuate; in the female it is still less truncate on each side, but yet 
scarcely sinuous.

170. Laccophilus restrictus, n. sp.—Ovalis, subdepressus, nitidus, testaceo-rufus, 
elytris fere eequaliter fusco-irroratis; prothorace valde transverso. Long. 32, lat. 
2m.m. 
The sexes in this species are not very easy to distinguish: the male has the 
front and middle tarsi but little imerassate, and the apical ventral segment has the 
hind margin acuminate in the middle and very oblique at the sides; in the female 
the middle part is scarcely longer than in the male, but it forms a broader lobe 
rounded at the extremity, and the hind margin close to the sides is more deeply 
sinuate. This species has the outline less narrowed in front than is usual in the 
genus.

171. Laecophilus solutus, n. sp.—Ovalis, subdepressus, nitidus, testaceo-rufus, 
elytris lineis tenuissimis, flexuosis et disintegratis, fuscis. Long. 4, lat. 24 m.m. 
The dark marks ou the elytra are fine, linear, and very irregular, and more or 
less broken up into short pieces, they leave the sides untouched, and become 
obsolete at the extremity. In the male the front and middle tarsi are moderately 
incrassate ; the apical ventral segment is produced in the middle and sinuate at 
each side of the hind margin, so as to forma small prominent middle lobe: in 
the female the hind margin is broadly rounded, being not much produced in the 
middle.
