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



Femora aud abdomen fulvous. Tibiae, tarsi, and the breast piceous 

 or black. 



Nikko. 



This species has the same shape as G. semifulva, but is smaller, of 

 paler colour ; the antennae are shorter aud have the third and fourth 

 joints equal (in the other species' the third joint is distinctly longer) ; 

 the jjunctuation of the elytra also is much stronger, and the legs are 

 of different colour. 



Galerucella fuscipennis, sp. nov. 



Elongate, convex ; black ; lower part of face, thorax, the base of 

 the femora, and abdomen testaceous ; thorax with three fuscous 

 spots ; elytra fuscous, finely pubescent and punctured, the lateral 

 margin obscure testaceous. 



Length 4 lines. 



Head finely rugose-punctate, black, with a fine central groove, the 

 lower part of the face testaceous. Antennae half the length of the 

 body, the second and third joints equal, the fourth distinctly longer, 

 closely pubescent. Thorax narrowly transverse, about three times 

 as broad as long, the sides but moderately rounded, the angles obtuse; 

 surface ratlier deeply depressed along the anterior margin, and with 

 three rather deeper foveas at the base, the middle one of which is of 

 triangular shape i the interior of these foveae is stained with black. 

 Scutellvim black, covered with long pubescence. Elytra obscure 

 fuscous, slightly tinged with green, their extreme base and the 

 lateral margin narrowly testaceous ; surface extremely closely and 

 finely punctured, thinly but closely covered with yellowish pubescence. 

 Femora fulvous at their base ; the knees, tibiae, tarsi, and the sides of 

 the breast black. Abdomen fulvous. 



Awomori. A single specimen. 



This species approaches in size G. annulicornis, Baly, but the 

 structure of the antennae in the latter is quite different, the thorax 

 is also of other shape, and the elytra have a broad flattened margin 

 which is wanting in the present species. 



Genus Galeruca, Geoffr. 



Galerxjca (Adimonia) multicostata, sp. nov. (Plate XLVI. 

 fig- 7.) 



Oblong, narrowly parallel ; black, above rufous ; thorax strongly 

 punctured with some deep foveae ; elytra deeply punctate-striate, 

 the interstices costate throughout. 



Length 2-3 lines. 



Head with a few fine and remotely placed punctures ; the frontal 

 tubercles black, very strongly raised and limited behind by a deep 

 groove ; palpi black. Antennae rather more than two thirds the 

 length of the body, black ; the second joint short, third and fourth of 

 equal length. Thorax about one half broader than long, subquadrate, 

 the sides very little rounded, the angles not produced ; the disk with 

 three deep longitudinal foveae and another transverse sulcation at the 

 base (these foveae are sometimes interrupted in such a way as to 

 form three impressions parallel with the anterior and three parallel
