pleasure in dedicating this insect to Herr E. Reitter, the 

 well-known microcoleopterist of Paskau. 

 Hab. Hiogo, near Maiyasan temple. 



Hister margine-punctatus, n. sp. 



H. ovalis, subconvexus, niger, nitidus, stria frontali subsinuata ; 

 pronoto lateribus punctato, stria integra, margine subelevato, 

 ante scutellum foveolato ; elytris striis 1.-4. dorsalibus integris, 

 5. et 6. medio abbreviatis ; propygidio pygidioque grosse sed parce 

 punctatis ; mesosterni lateribus parce punctatis. L. 2| lin. 



Allied to the European H. marginatus, from which the larger 

 size and system of striation easily separate it. 

 Hab. Hakodate. 



Hister simplicisternus , n. sp. 



H. ovatus, niger, nitidus ; fronte impressa, stria integra ; pronoti 

 stria laterali interna integra, externa abbreviata ; elytris striis 

 1.-3. dorsalibus integris, 4. et 5. et suturali brevibus ; propygidio 

 punctato, subfoveolato ; pygidio apice subtiliter punctato ; meso- 

 sterno marginato, basi non sinuato. L. 2|-3 lin. 



Much smaller than sibiricus, Mars., to which section it be- 

 longs ; it may be recognized by the finer punctation of the 

 pygidium (in some specimens almost smooth at the apex), and 

 by the mesosternum having no notch to admit the pro- 

 sternum. 



Hab. Hiogo, where it is common. 



Bacanius niponicus, n. sp. 



B. ovalis, convexus, rufo-castaneus, undique sat dense puncta- 

 tus ; pronoti stria integra, linea basali arcuata e punctis paueis 

 composita ; elytris haud striatis ; antennis pedibusque rufo- 

 brunneis. 



Near B. rhombophorus, Aube, but half as large again ; the 

 punctures are coarser and more equally distributed ; and the 

 punctured line before the scutellum is a simple bow of twelve 

 or thirteen points. 



Hab. Nagasaki ; under dead leaves at Suwosama temple 

 in April. 



Acritus komai, n. sp. 



A. ovalis, convexus, piceus, nitidus, supra dense punctatus ; pro- 

 noto linea basali punctorum transversa impresso ; antennis pedi- 

 busque int'uscatis. 



Very near A. minutus, Herbst, and of the same stature, but 

 more closely punctured, especially on the doival region. The
