1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 743 



cJ . Head impunctate, deeply grooved between the antennse. Eyes 

 large and prominent. Antennse black or Cuscous, twice as long as 

 the body, the second joint short, the third more than three times as 

 long, the rest more elongate and slender. Thorax subcjuadrate, one 

 half broader than long, all the angles produced in a tooth, the sides 

 straight ; surface somewhat depressed at the disk, remotely punctured 

 at the sides and near the basal margin, the middle of the disk almost 

 impunctate. Scutellum smooth, impunctate, black. Elytra parallel, 

 rather convex, much more strongly punctured than the thorax, and 

 the punctuation arranged in very close irregular rows, the interstices 

 slightly wrinkled at the sides. Legs blackish, the apices of the 

 tibiae and the tarsi sometimes obscure testaceous. 



5 . Eyes much smaller and less prominent, the third joint of the 

 antennse only one half longer than the second.

Genus Luperodes, Motsch. 



LUPERODES NIGRIPENNIS, MotSch. 



Two specimens from Obaru I must refer to this species, with the 

 description of which they agree very nearly. In one of the Japanese 

 specimens the first joint of the antennse is fulvous, and the sides of 

 the head are marked with black ; all the rest agrees with Mots- 

 chulsky's description. In the other, which is of nnich smaller size, 

 the head and the abdomen are entirely black, and the apices of the 

 femora are more or less testaceous. 



In the absence of more specimens for comparison, I cannot say 

 whether the Japanese insects may represent another species or 

 varieties of Motschulsky's type. 



Genus Galerucella, Crotch. 

 Galerucella nigromarginata, sp. nov. (Plate XLVI. fig. 10.) 



Narrowly elongate, parallel ; black ; lower part of the face and 

 the thorax testaceous, the latter with three spots ; elytra rugosely 

 punctured, finely pubescent, testaceous, the sutural and lateral 

 margin narrowly black ; legs testaceous. 



Length 2 lines. 



Head rugose-punctate, black ; the frontal tubercles and the lower 

 part testaceous. Labrum black. Antennse half the length of the 

 body, black, the two basal joints testaceous below, the third joint 

 very slightly longer than the fourth. Thorax twice as broad as 

 long, the sides distinctly angulate at the middle, the posterior angles 

 acute and strongly obliquely shaped ; surface with an obsolete de- 

 pression at the sides, rather strongly rugose-punctate, testaceous ; a 

 round black spot is placed at each side and a more square-shaped 

 one at the middle. Scutellum black, finely punctured. Elytra 

 testaceous, the disk slightly darker, the sutural and lateral margins 

 narrowly edged with black ; the surface very closely punctured, the
