736 MR. M. JACOBY ON THE [Nov. 3, 



Vertex impunctate, the frontal tubercles narrowly anrl transversely 

 shaped. Labrum and palpi fulvous. Antennae two thirds the length 

 of the body, the third and fourth joints equal and smaller and 

 thinner than the second, the four or sometimes the five basal joints 

 and the apex of the terminal one fulvous, the others black. Thorax 

 twice as broad as long:, the posterior margin distinctly sinuate at 

 each side near the middle ; surface closely and finely punctured, 

 leaving a narrow middle line smooth ; anterior angles narrowly 

 fulvous. Elytra strongly convex, narrowed near the apices, the 

 shoulders not prominent, the punctuation more distinct than that of 

 the thorax, and arranged in close and rather irregular rows, a 

 broader space in front of the lateral margin impunctate. Posterior 

 femora black, the others and the tibiae and tarsi fulvous, the third 

 joint of the latter much broader than the second. 



Oyama, Kiga, Nikko. 



Separated from S.japana, Baly, and S. separata by the entirely 

 black, not blue, colour of the upper side, by the fulvous angles of the 

 thorax, and the more closely and finely punctured elytra, as well as 

 by the colour of the labrum and palpi. 



Sph^roderma abdominalis, sp. nov. 



Ovate ; black, apices of the elytra and the abdomen flavous ; 

 thorax very finely punctured ; elytra regularly and distinctly 

 punctate-striate. 



Var. The sides of the elytra fulvous. 



Length 1|-1| line. 



Head entirely impunctate, the frontal tubercles very obsolete. 

 Antennae stout, more than half the length of the body, the first 

 three joints fulvous, the basal ones stained with black above, the 

 rest entirely of that colour, the second and third joints equal in length. 

 Thorax transverse, the sides rounded and narrowly margined, the 

 anterior angles thickened and oblique, the posterior margin strongly 

 sinuate near the scutellum ; surface covered with very small and 

 some larger punctures, the latter not very closely and irregularly 

 placed. Elytra wider at the base than the thorax, the shoulders 

 prominent and impunctate, the disk rather strongly punctate-striate, 

 the striae near the suture more closely placed and more irregular 

 than the others ; the apices of the elytra flavous, this colour narrowed 

 and extending upwards a little at the lateral margin. Legs black.

Entirely fulvous ; head impunctate ; thorax scarcely visibly, elytra 

 distinctly and remotely punctured. 



Length Ig line. 



Head impunctate, the frontal tvibercles transverse, the carina 

 flattened and short. Antennae more than half the length of the 

 body, fulvous, the second and third joints short and of equal length, 

 the following gradually thickened. Thorax transverse, widened at
