1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 729 



versely wrinkled or finely rugose head, in connection with the black 

 suture of the elytra, which in shape agrees with L. atricilla, Gyll., 

 but this species is smaller and has a blackish head. 



LONGITARSUS aUADRATICOLLIS, Sp. HOV. 



Obscure dark fulvous ; antennae as long as the body ; thorax 

 subquadrate, impunctate ; elytra finely semipunctate-striate. 



Length | line. 



Head impunctate, the frontal tubercles very narrow and trans- 

 verse. Antennae flavous, the second and third joints short and 

 equal. Thorax very nearly square-shaped, the sides straight, the 

 anterior angles scarcely oblique, surface entirely impunctate. Elytra 

 nearly parallel, but little narrowed behind, finely and rather regularly 

 punctured. Legs flavous, the posterior femora darker, the meta- 

 tarsus rather longer than half the tibiae. 



Nara. 



Amongst the small species of the present genus L. quadraticollis 

 is somewhat closely allied to L. pusillus, but may be distinguished 

 by the square-shaped and impunctate thorax. The elytra are larger 

 at the base than the latter, and their shoulders are slightly 

 prominent. 



LoNGiTARsus LYCOPi, Foudr. 



The only difference I am able to find in the Japanese specimens 

 from those of Europe is the slightly larger size of the former ; all 

 other characters agree so closely that I see no reason to consider 

 the two specimens obtained at japan (Tisac ?) as specifically distinct. 



LoNGiTARSus PARVULA ?, Allard. 



A single specimen resembling this species extremely closely was 

 obtained; the elytra are rather more strongly punctured than in the 

 European form. 



Genus Aphthona, Chevr. 

 Aphthona FOXJDRASi, sp. nov. 



Breast and abdomen piceous or black ; head and thorax pale 

 fulvous, nearly impunctate ; elytra testaceous, very finely semireo-u- 

 larly punctate; legs testaceous, apices of the posterior femora 

 piceous. 



Length | line. 



Head impunctate, dark fulvous, the frontal tubercles in shape of 

 narrow transverse ridges. Antennse rather short, flavous or testa- 

 ceous, the four or five terminal joints fuscous. Thorax transverse, 

 of equal width, twice as broad as long, the sides nearly straight, 

 surface scarcely or microscopically finely punctured. Scutellum 

 piceous. Elytra slightly narrowed behind, finely but distinctly 

 punctured, the punctuation arrauged in close, rather regular lines 

 which almost entirely disappear at the apex ; the first joint of the 

 posterior tarsi as long as the two following joints together.
