404 M. JACOBY ON NEW SPF.CIES OF BEETLES. [JuilC 19, 



to apex : upper surface obsoletely three-foveolafe, fulvous or flavous, 

 closely rugose-punctate. Scutellum trigonate, closely punctured. 

 Elytra much widened towards the apex, narrowly margined below 

 the middle at the sides, very closely and finely granulose-punctate, 

 of a bright green, but little shining, with a slightly sinuate traus- 

 verse flavous band below the middle extending to either margin. 



In my collection. 



The present species forms the second one known from Africa, and 

 seems allied to M. limbata, Baly, from which the flavous elytral 

 band and want of the similarly coloured margins of the elytra 

 separate it. 



Merista, Chap. 



10. Merista OBERTHURi. (Plate XLV. fig. 10.) 



Oblong-ovate, widened behind, black ; thorax impunctate ; elytra 

 very finely punctured, the extreme lateral margin, a narrow transverse 

 band before, and two others behind the middle flavous ; claws 

 bifid, the inner division small. 



Length 4h-5 lines. 



Head impunctate, black. Thorax subquadrate, the anterior angles 

 slightly produced and thickened ; surface impressed with two trans- 

 verse shallow grooves, of which the first is situated close to the 

 anterior margin, the second near the middle, more deeply impressed 

 and obliquely shaped at the sides ; disk impunctate, with the ex- 

 ception of a few punctures along the anterior and jjosterior margins. 

 Scutellum broad, impunctate. Elytra much wider at the base than 

 the thorax, distinctly widened behind, very greatly in the female, 

 entirely black, very finely punctured, the punctures now and then 

 arranged in semi-regular rows ; the extreme lateral margins, a very 

 narrow transverse band before, two others more closely approached 

 behind the middle, and the posterior part of the suture flavous. 



Hab. Thibet (Tatsi^ulon Mount). Collection Oberthiir and 

 Jacoby. 



The antennae are more than two thirds the length of the body, 

 and of the usual structure to be found in the present genus. Of 

 the three bands at the elytra the middle one extends generally to 

 the lateral margin, which is not the case with the other two. From 

 all the described species, the present one, of which I have seen six 

 specimens, sent to me by M. Oberthiir for determination, is easily 

 distinguished by its coloration. 



Physonychis, Chap. 



11. Physonychis nigricollis, sp. nov. (Plate XLY. fig. 11.) 



Elongate, subparallel, flavous below ; base of the head and the 

 thorax black ; elytra metallic green or blue, closely rugose-puuc- 

 tate. 



Length 4-4 1 lines. 



Head closely and distinctly punctured at the vertex, the latter 

 black ; frontal tubercles highly raised, elongate ; the latter and lower
