1885.J PHYTOPHAGOUS COLEOPTERA OF JAPAN. 723 



contiguous ; antennae more than half the length of the body, 

 entirely fulvous, the second and third joints short and equal, fourth 

 slightly longer ; thorax not much more than one half broader than 

 long, the sides narrowed at the base, rounded at the middle, the 

 anterior angles oblique, the basilar sulcation deep and well limited 

 laterally by a longitudinal groove, surface impuiictate. Elytra 

 strongly narrowed behind, the punctured strise very regular and fine, 

 still less strongly marked at the apex ; the first joint of the posterior 

 tarsi as long as the two following joints together. 



Nikko. A single specimen. 



Nf^rrower, less convex, and of lighter colour than C. IcevicoUis, 

 the thorax longer and less transverse, the strias at the elytra much 

 more regular and composed of single punctures only. The shape of 

 this species is very pointed posteriorly, and the sides of the thorax 

 are concave near the base, both characters which will assist in the 

 recognition of the present insect. 



Crepidodera japonica, sp. nov. 



Black or piceous ; thorax strongly punctured within the basilar 

 groove ; elytra distinctly punctate-striate. 



Length ]|-2 lines. 



Head impunctate, deeply grooved between the eyes ; frontal 

 tubercles elongate, strongly raised, fulvous or piceous ,- palpi dark 

 fulvous ; antennae two thirds the length of the body, black, the apices 

 of the basal joints stained with fulvous, third and fourth joints of equal 

 length. Thorax subquadrate, slightly broader than long, the sides 

 rounded before the middle, constricted near the base, the latter with 

 a deeply impressed transverse groove, limited at the sides by a perpen- 

 dicular sulcus; surface rather convex, the disk impunctate, the lateral 

 margin accompanied by a deep row of punctures which extend also 

 across and within the basilar groove. Elytra with distinct and regular 

 rows of punctures, which are a little less deeply impressed near the 

 apices, the latter being of a somewhat paler colour than the rest of 

 the surface. Legs covered with yellowish pubescence. 



Nikko. 



The rather large size and entirely black or piceous colour will 

 assist in distinguishing this species. The transverse groove of the 

 thorax extends nearly to the sides, is strongly punctured, and not so 

 well bounded laterally by a perpendicular groove as is the case in 

 most of the species in this genus. The frontal tubercles also are 

 very strongly developed, and sometimes of an obscure fulvous colour. 



Crepidodera bimaculata, sp. nov. 



Fulvous ; antennae, tibiae, and tarsi black ; thorax impunctate ; 

 elytra finely subgeminate punctate-striate, fulvous, each elytron with 

 an obscure fuscous spot near the apex. 



Length 2 lines. 



Head finely transversely strigose at the vertex, impunctate, the 

 frontal tubercles strongly raised, elongate, and bounded behind by a
