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



the size and differ in the coloration of the head and thorax, which 

 is black in S. intermedia. The antennae in the latter are not thick- 

 ened as in S.fulijida, in which character it seems to agree with the 

 sjiecies described by Von Harold ; this autlior gives, however, the 

 punctuation of the elytra as more strong than in S.fulgida, while 

 in the present species it is' of about the same strength, but the striae are 

 more distantly placed, geminate anteriorly only, and the interstices 

 are finely punctured. In the absence of other specimens all doubt 

 as to the specific value of >S'. intermedia is not excluded. 



Sphenoraia melanocephala, sp. nov. 



Black ; thorax and elytra fulvous, the former strongly punctured, 

 the latter subgeminate punctate-striate, tlie interstices closely and 

 more finely punctured. 



Length .3 lines. 



Head black or piceous, with a deep triangular groove between the 

 eyes, the vertex with a few fine punctures. Antennae black, two 

 thirds the length of the body, second and third joints short, the 

 following somewhat flattened and widened, the three lower joints 

 shining, the rest opaque, pubescent. Thorax more than twice as 

 broad as long, the sides rounded, the anterior angles obliquely shaped, 

 the posterior margin oblique at the sides, straight at the middle ; the 

 disk with a deep transverse depression at each side, the latter strongly 

 and irregularly punctured. Elytra convex, parallel, fulvous like the 

 thorax, the space near the suture deeply punctate-striate, the punc- 

 tures slightly approached in double rows, the sides as deeply but 

 ii regularly punctured, the interstices everywhere finely punctured, 

 those at the sides slightly transversely wrinkled. Underside and 

 legs black. 



Yuyama. Four specimens. 



This species has ail the structural characters of the genus pointed 

 out by i\Ir. Baly and Herr von Harold. 



Genus Monolepta, Eriehs. 



MONOLEPTA CYANEA, Sp. nOV. 



Black below, above dark blue ; second and third joints of the 

 antennae testaceous; thorax scarcely visibly, elytra finely punctured. 



Length li line. 



Head impuuctate, with a deep fovea at the middle above the 

 antennae ; the latter two thirds the length of the body, black ; the 

 second and tliird joints testaceous, the latter one half longer than 

 the preceding joint. Thorax one half broader than long, subquad- 

 rate, rather convex, the sides rounded before the middle, straight 

 near the base, surface extremely finely piuictured. Elytra extremely 

 closely and much more distinctly punctured. Underside and legs 

 black. 



Nikko, Yuyama, Miyanoshita, Suyama, Subashiri. 



Of the same coloration as Jf._/?a2J2yewfm in regard to the upper 

 surface, but smaller, the abdomen entirely black, and the antennae of 

 different colour.
