1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 727 



punctate ; the piceous or nearly black colour of the upper surface 

 will help to distinguish the species from the many blue-coloured 

 allied forms. 



Haltica liEwisi, sp. nov. 



Entirely fulvous or testaceous ; thorax transversely subquadrate, 

 closely punctured ; elytra closely subrugose-puuctate. 



Length 1 1 line. 



Head impunctate, shining, the frontal tubercles distinctly raised 

 out short. Antennse half the length of the body, rather robust, 

 entirely fulvous, the second joint thickened, scarcely shorter than the 

 third, this and the following joints of nearly equal length. Thorax 

 twice as broad as long, subquadrate, the sides straight, the anterior 

 angles acute but not produced, the base with an obsolete transverse 

 sinuate groove which has a deeper depression or fovea at the middle 

 of the basal margin ; surface not very closely but distinctly punctured, 

 the punctures more deeply impressed within the basilar groove. 

 Elytra closely and much more strongly punctured than the thorax, the 

 interstices shghtly rugose ; first joint of tbe posterior tarsi as long as 

 the two following together. 



Kashiwagi, Chiuzenji. 



The four specimens before me do not differ in any way ; in all, the 

 groove of the thorax is plainly visible, although not strongly defined 

 in outline. 



Genus Longitarsus, Latr. 



Longitarsus nitida, sp. nov. 



Fulvous, shining ; head finely transversely rugose ; thorax trans- 

 verse, distinctly punctured ; elytra not more strongly punctured, 

 narrowed behind ; antennae as long as the body. 



Length 2 lines. 



Head with a few deep punctures and a fovea near the inner 

 margin of the eyes ; the frontal tubercles not raised, but limited 

 behind by an oblique groove; carina broad, not strongly raised. 

 Antennae as long as the body, entirely fulvous, the apex of the 

 terminal joint fuscous, the third about one half longer than the 

 second joint. Thorax nearly three times as broad as long, the 

 sides rather strongly deflexed, lateral margin a little rounded at the 

 middle and slightly converging outwards, the anterior angles broadly 

 oblique, forming a tooth at a little distance before the middle, surface 

 rather convex, closely and finely punctured. Elytra widened towards 

 the middle, strongly narrowed at the apex, the shoulders rounded ; 

 the disk not more strongly but a little more distantly punctured. 

 Metatarsus of the posterior legs one half the length of the tibiae. 



Sapporo. 



L. nitidus resembles in size our L. verbasci, but is of a narrower, 

 posteriorly more pointed shape, and the punctuation of the thorax is 

 more distinct, and that of the elytra more remotely placed ; the third 

 joint of the antennae is also proportionately longer than in the Euro- 

 pean species.
