1885.] COLEOPTERA FROM JAPAN. 205 



Genus Nodostoma, Motsch. 



NODOSTOMA JAPONICUM, Sp. IIOV. 



Black ; head and four basal joints of the antennae fulvous ; head 

 and thorax closely and strongly punctured ; elytra with the base 

 swollen, distinctly punctate-striate. 



Length 2 lines. 



Head entirely fulvous, closely and very strongly punctured, the 

 middle impressed with a short longitudinal groove ; epistouie broader 

 than long, separated from the face by an irregular transverse groove. 

 Terminal joints of the antennae slightly and gradually thiGkened, the 

 four lower j oints fulvous, the rest black ; second and third joints of nearly 

 equal length. Thorax about twice as broad as long, the sides angulate 

 immediately below the middle ; surface closely covered with deep and 

 round ])unctures, which at the middle of the disk are now and then 

 confluent. Scutellum impunctate. Elytra with the base strongly 

 swollen, deeply depressed below the latter and within the humeral 

 callns, from which a short costa runs obliquely towards the lateral 

 margin ; the punctuation is strong within the basilar depression, more 

 finely impressed and very regular at the rest of the surface ; the 

 suture is accompanied by two rows of punctures, the latter near the 

 other portion of the apex is very fine. Femora with a small tooth, 

 the knees sometimes as well as the base of the tibiae dark fulvous. 



Kisa. 



I cannot find amongst the many eastern forms contained in this 

 genus a species of similar coloration, which is the same in the two 

 specimens I have for examination. All the femora are armed with 

 a small tooth, and the thorax is angulate directly below the middle 

 and not close to the base, as is the case in many other species of 

 Nodostoma. The claws are appendiculate as usual. The two speci- 

 mens before me are evidently females. 



Nodostoma ruficolle, sp. nov. (Plate XI. fig. 10.) 



Underside, legs, terminal joints of the antennae, and elytra black; 

 head and thorax rufous, strongly punctured ; elytra -with the base 

 swollen, punctate-striate. 



Length 2 lines. 



Head strongly rugose-punctate, the epistcme separated from the 

 front only by some smooth raised longitudinal spaces. The four 

 basal joints of the antennae fulvous, the rest black, fourth joint 

 shghtly longer than the third. Thorax narrowly transverse, the 

 sides obsoletely angulate near the base, its surface rather convex, 

 rufous like the head, remotely and strongly punctured. Elytra with 

 a distinct depression within the shoulder and below the base, the 

 latter strongly raised and with but few punctures, the latter more 

 crowded and deeply impressed within the depression ; rest of the 

 surface more finely and remotely punctate-striate. Intermediate 

 and posterior femora with a minute tooth.
