198 MR. M. JACOBY ON NEW [Feb. 17, 



closely placed. Lamprosoma cupreatum, Baly, is of double the size 

 and quite differently punctured, also less narrowed behind. Nearly 

 a dozen specimens were obtained. 



Lamprosoma cupreatum, Baly. 



Nearly all the specimens in this collection which I refer to Mr. 

 Baly's species are smaller, more attenuated behind, and varying in 

 the'degree of their punctuation and colour. In the absence of other 

 characters I have refrained from describing them as new, and believe 

 that they only represent a local variety. 



Genus Chlamys, Knoch. 



Chlamys japonica, n. sp. (Plate XI. fig. 5.) 



Subquadrate-ovate, obscure piceous ; head more or less fulvous ; 

 thorax with a posterior elevation, closely punctured and covered with 

 fulvous tubercles ; elytra strongly punctured, with a strongly raised 

 oblique ridge from the middle of the base to the suture, and 

 divided by other transverse irregular ridges ; legs obscure fulvous. 



Length 1|-1| line. 



Head closely rugose-punctate, rather flattened, light or darker 

 fulvous. Antennas of the same colour, the fifth and following joints 

 transversely widened, third and fourth joints of equal length. Thorax 

 with the middle portion gradually raised posteriorly in a moderate 

 but distinct gibbosity, the apex of which is slightly longitudinally 

 depressed, and the sides obliquely and rather deeply grooved or 

 constricted : the swollen portion of the thorax, as well as the more 

 flattened sides, are covered with irregular flavous or fulvous tube- 

 rosities, the interstices of which are closelv punctured. Scutelluni 

 greatly transversely dilated posteriorly, the lateral angles acute and 

 produced, and its posterior margin concave. Elytra slightly narrowed 

 towards the apex, the sides rather strongly constricted at the middle ; 

 surface covered with deeper and much larger punctuation than that 

 of the thorax ; when viewed sideways the following longitudinal 

 ridges are seen : — a narrow one from the middle of the base runs in 

 an oblique direction towards the suture near the apex ; the anterior 

 portion of this ridge is narrow and acute to the middle, where it is 

 intersected by a transverse ridge whicli runs from the shoulder to 

 the suture ; the portion of the ridge from the middle to the place 

 where it touches the suture is broader and very strongly raised, 

 which makes the space enclosed by it appear as being excavated ; 

 near the apex three more strongly raised tubercles placed triangularly 

 are seen ; a short transverse ridge is further visible at the sides 

 within the constricted space ; the suture itself is distinctly denticu- 

 late through its entire length. Pygidium closely punctured, with 

 three obsolete longitudinal costse. 



Kiga, Fukushima. 



The raised parts of the thorax and the elytra in this species are 

 frequently of a flavous or fulvous colour, which sometimes is that of 

 the entire head and thorax. The species is closely allied to C.
