7-14 MR. M. JACOBS ON THE [NoV. 3, 



interstices transversely wrinkled and sparingly covered with short 

 yellowish hairs. Legs testaceous,, the tarsi somewhat darker. 



Principally distinguished by the three-spotted thorax, in connection 

 with the narrow black sutural and lateral margins of the elytra, which 

 colour separates the species from G. nymphaa, L., to which it seems 

 closely allied ; but in the latter the margins of the elytra are paler 

 than the disk, and show no trace of darker colour. 



Galerucella semixigra, sp. nov. 



Elongate, parallel, subcylindrical ; black; elytra fulvous, pubescent ; 

 head and thorax very finely punctured, the posterior margin of the 

 latter obscure fulvous ; elytra extremely finely and closely punctured. 



Length 3| lines. 



Head broadly depressed at the middle, finely and closely rugose- 

 punctate, labrum margined with testaceous. Antennae half the length 

 of the body, the second and third joints of equal length, and shorter 

 than the other joints, their apices more or less testaceous. Thorax 

 more than three times as broad as long, the sides slightly rounded 

 at the middle, nearly straight at the base, the posterior angles 

 oblique ; the surface with three deep longitudinal depressions, the 

 central one of a more triangular shape ; middle of the disk very 

 finely, the sides more strongly punctured, rather shining ; black, the 

 posterior margins oliscurelv edged with fulvous. Scutellum broad, 

 its apex broadly rounded, black, pubescent. Elytra reddish fulvous, 

 extremely closely and finely punctured, and covered with yellowish 

 hairs. Underside and legs black ; the first joint of the posterior 

 tarsi slightly longer than the second. 



Yagohara. A single specimen. 



Principally distinguished by the black head and thorax, and the 

 fulvous elytra, in connection with its rather larger size. 



Galerucella viridipennis, sp. uov. (Plate XLVI. fi;;. 9.) 



Elongate, parallel; black ; head and thorax finely rugose-punctate; 

 elytra metallic green, finely rugose and pubescent. 



Length 2 lines. 



Head rugosely punctured, the frontal tubercles divided by a deep 

 groove. Antenna; black, nearly as long as the body, the third 

 joint double as long as the second, but much shorter than the fourth, 

 the following joints gradually decreasing in length. Thorax twice 

 as broad as long, the sides shghtly rounded, the anterior and 

 posterior margin straight ; the disk with a transverse deep depression 

 at each side, which is but slightly interrupted at the middle, rather 

 finelv and irregularly punctured and sparingly covered with yel- 

 lowish hairs. Scutellum black. Elytra bright metallic green, very 

 finely and closely rugose, sparingly pubescent. Tibiae unarmed. 

 Claws bifid. Anterior coxal cavities closed. 



Kurigahara, Wada toge. 



Of this handsome species a good many specimens were obtained ; 

 the bright green elytra, and black head and thorax will at once assist 

 in its recognition.
