the rest gradually increasing in size, fulvous. Thorax narrow, 

 transverse, the posterior margin strongly rounded, the sides straiglit' 

 slightly thickened in front of the margin, the surface very closely 

 and finely punctured. Elytra rounded, punctured like the thorax, 

 the inner margin of their epipleuree placed far inwards ; each elytron 

 with a small black spot at the shoulder, another near the scutellum, 

 three others, of which the third is sutural and common to both 

 elytron, placed behind the anterior ones near the middle, and a small 

 spot at the apex ; the apices of the femora, tibiae, and tarsi fulvous, the 

 rest of the underside piceous. Prosternum elongate, rather broad; 

 coxal cavities open. 



Sapporo. 



In one of the specimens the elytral spots are very obscure and of 

 a dark fulvous colour, but their p'osition is the same as in the other. 



Genus Psylliodes, Lair. 



PSYLLIODES SUBRUGOSA, Sp. UOV. 



Piceous below ; antennaj and tibiae fulvous ; above dark blue ; 

 head and thorax closely punctured ; elytra stronglv puncfcate-striate] 

 the interstices finely punctured and slightly ru»ose. 



Length 1 line. 



Head distinctly punctured (when seen under a strong lens). 

 Antennae entirely fulvous, the second and third joints of equal length. 

 Thorax rather convex, about twice as broad as long, the surface 

 closely and more strongly punctured than the head, with an indi- 

 stmct central raised line. Elytra rather broad and convex, and 

 strongly punctate-striate, the interstices fiaely punctured,' and 

 slightly rugose at the sides. Legs piceous; the knees, tarsi, and 

 the posterior tibiae fulvous. 



Hakodate. A single specimen. 



From the other three known Japanese species the present one is 

 separated by its shorter, broader, and more convex shape, especially 

 m regard to the thorax, the punctuation of which is much strono-er 

 than HI the allied species ; further, by the entirely fulvous antenna; 

 ni connection \nt\\ the slightly wrinkled interstices of the elytra, 

 which is principally to be seen at the sides when the insect is held 

 in a certain light. In P. angusticdllis, Baly, the elytral punctuation 

 IS much finer. 



PSYLLIODES INTERMEDIA, Sp. UOV. 



Piceous ; above dark blue ; antennae black, the two basal joints 

 testaceous ; thorax extremely finely punctured ; elytra very deeply 

 punctate-striate, the interstices costate at the sides, finely punctured 

 and wrinkled. 



Length 1 line. 



Otsu. A single specimen. 



The head in this species is impunctate ; the antenna, with the 

 exception of the two first joints, entirely black; the thorax is
