56 Mr. Gr. Lewis on Erotylidse^'om Japan. 



Nagasaki, Nikko, and Sapporo. It varies in size from 3 to 

 4^ millim. 



Dacne picta. 



Dacneincta, Crotch, I. c. p. 188 (1873), 



Common at Nagasaki and near Yokohama. Found under 

 the bark of Planera in winter. 



Dacne zonaria. 



Elongato-ovalis, nigra, nitida ; elytris macula humerali tarsisque 

 rufis. L. 3| mUl. 



Densely black and shining ; head and thorax sparsely and 

 somewhat coarsely punctate, the latter strongly marginate 

 laterally ; elytra punctate-striate, with punctures in lines 

 down the interstices, punctures rather finer than those of 

 thorax, one red belt, oblique, touching the edge only at the 

 humeral prominence at the base, leaving a black margin both 

 at external and sutural edges; the hamate pattern, so com- 

 mon in the family, is rather broad at the scutellum. The 

 antennae, sometimes obscurely reddish at the base, are some- 

 what long and the club somewhat free ; the tarsi and knees 

 are reddish. Beneath, the head and prosternum are coarsely 

 and rather rugosely punctured ; the intercoxal lines reach 

 the base of the prosternum ; the mesosternum is rather finely 

 punctured. 



The colour separates this species from the other Japanese 

 species, and the antennse are proportionally longer, with the 

 club lax. It is also unlike any other species I know. 



Found at Kiga, Miyanoshita, and Nikko abundantly ; 

 Konose, Fukushima, and Sapporo are other localities for it. 



Dacne fungorum. 



Oblonga, nigra, nitida ; elytris macula humerali, capita, antennis 

 pedibusque rufis. L. 3 mill. 



Oblong, black and shining ; head and thorax sparsely and 

 rather coarsely punctate, the first red, the latter black, with 

 lateral margin obscurely piceous and anteriorly narrowly con- 

 colorous with head ; elytra punctate-striate, interstices some- 

 what similarly punctured, with a red irregular blotch at the 

 humeral angle which touches the edge only at the base; 

 antenuEe, legs, and tarsi wholly red. Beneath, the prosternum 

 is very minutely rugose and punctured somewhat similarly to 

 the metasternum ; the intercoxal or prosternal striae advance 

 anteriorly a little beyond the cox£e, and posteriorly touch
