154 Mr. M. Jacoby’s descriptions of some new 
Psylliodes sumatrensis, n. sp. 
Black, upper side metallic green, the three basal joints of the 
antenne fulvous; thorax strongly and closely punctured; elytra 
distinctly punctate-striate, the interstices very finely punctured. 
Length, 13 line. 
Head remotely and finely punctured, without transverse groove, 
metallic green, the frontal elevations very narrow, oblique ; labrum 
and palpi black; antenne scarcely extending to half the length of 
the elytra, black, the lower three joints fulvous, the third joint 
shorter than the second; thorax one-half broader than long, the 
sides straight, the anterior angles oblique, the surface strongly and 
closely punctured throughout; elytra rather strongly punctate- 
striate, the interstices flat, very finely punctured; under side and 
legs black, the posterior femora stained with metallic green. 
Hab. Sumatra. 
Nearly allied to P. diffcilis, Baly, from Japan, but the 
thorax less transverse, the antenne much shorter, the 
posterior margin of the thorax not bisinuate, the sur- 
face more closely punctured, the elytral interstices flat 
throughout, and the general upper surface green instead 
of blue. 
Liprus flavilabris, n. sp. 
Dark piceous, with the labrum, antenne, and the four anterior 
legs flavous ; thorax bisulcate, impunctate ; elytra deeply punctate- 
striate, the base strongly raised. Length, 13 line. 
Of nearly black colour. The head impunctate, the frontal eleva- 
tions trigonate; labrum and palpi flavous; antenne filiform, 
flavous, the terminal joints slightly and gradually thickened ; 
thorax scarcely longer than broad, the sides deeply constricted 
below the middle, the surface impunctate, deeply transversely 
suleate near the base, the anterior portion with a more feeble 
suleus, the disc with a few whitish hairs; elytra with the basal 
portion convex, bounded below by a deep transverse depression, 
strongly punctate-striate, the interstices slightly convex, the sides 
perpendicularly depressed, the disc very sparingly pubescent ; legs 
flavous, the posterior femora piceous. 
Hab. Java. 
This species, of which a single specimen is contained 
in my collection, difiers from its congeners in the bi- 
sulcate and entirely impunctate thorax, as well as by its 
coloration,
