732 MR. M. JACOBY ON THE [NoV. 3, 



surface closely and finely punctured, the interstices somowhat 

 wrinkled. Elytra strongly and regularly punctate-striate, the 

 interstices impunctate and sHghtly convex, costate at the sides and 

 apex. Legs fulvous, the tibiae with a darker more or less distinct 

 mark, the posterior femora dark aeneous. 



Hosokute. 



C. chalceola is evidently closely allied to C. granulifrons, Baly, 

 of which I have the type for comparison, but in that species the 

 thorax is more finely punctured as well as the elytra; the antennae 

 are nearly entirely fulvous as well as the tibiae, and the shape of 

 the insect is rather narrower and less robust. It may be, however, 

 that the present insect is but a local form of Baly's species. 



Ch^tocnema japonica, sp. nov. 



Ovate, convex, aeneous ; antennae and legs fulvous ; head rugose- 

 punctate ; thorax closely and strongly punctured ; elytra deeply 

 punctate-striate, the interstices minutely punctured. 



Length 1| line. 



Head extremely finely granulate, strongly and very closely 

 punctured throughout, the punctures sometimes confluent. Antennae 

 not extending further than the base of the elytra, fulvous, the apices 

 of all the terminal joints stained with fuscous ; the second, third, and 

 fourth joints of nearly equal length. Thorax transverse, slightly 

 widened at the middle, the sides slightly rounded ; surface closely 

 covered with round punctures, which are more strongly impressed at 

 the sides than at the disk, the latter with a more or less distinct 

 central, smooth, longitudinal space. Elytra a little widened towards 

 the middle, very strongly and regularly punctate-striate; the inter- 

 stices minutely punctured when seen under a strong lens, costate at 

 the sides. Legs pale fulvous, the posterior femora stained with 

 greenish aeneous. 



Hakodate, the sandhills, Fukushima, Niigata. 



Closely allied to C. ingenua, Baly, from China, hut more robust 

 and of larger size, the head more strongly and closely punctured, 

 and the elytral interstices minutely punctate ; in C. ingenua the 

 latter are impunctate. 



Ch.etocnema kulvipes, sp. nov. 



Dark aeneous ; antennae, anterior legs, and posterior tibicc fulvous ; 

 head and thorax closely punctured ; elytra deeply punctate-striate, 

 the interstices sparingly punctured. 



Length IJ line. 



Head closely rugose-punctate, the frontal tubercles and the carina 

 entirely absent, lower part of face covered with some yellowish 

 pubescence ; palpi fulvous ; antennae of the same colour, scarcely 

 half the length of the body, the second joint as thick as, but one half 

 shorter than, the first, the following three as long as, but much thinner 

 than, the second joint, the terminal five short and of equal length. 

 Thorax nearly three times as broad as long, the sides very slightly 

 rounded, surface finely but very closely punctured, the punctures
