It is more tlian probable that this is a type of a tropical 

 genus. 



Ilah. Icliiuclii. Four examples on the Ist May, 1881. 



Uloma lotimanus.

This species is relatively longer than U. honzica, Mars., 

 and measures 7 to 13 mill. The small examples are often 

 pale in colour, like those recorded by Marseul tor U. honzica. 



Hah. Miyanoshita, Hakone, and Chiuzenji. Common. 



Corticeus colydioides^ sp. n. 



Cylindricus, elongatus, niger, nitidus ; antennis tibiisque concolori- 

 bus, tarsis rufis ; capita thoraceque punctulatis ; elytris striato- 

 punctulatis. 



L. 5-5| mill. 



Cylindrical, elongate, black, shining; the head clearly and 

 somewhat densely punctulate ; the thorax rather less closely 

 punctulate, much longer than broad ; the elytra striate-punc- 

 tate, witli a few very fine punctures on the interspaces also 

 longitudinally arranged ; the pygidium exposed and punctu- 

 late ; the tibiee angulate near the tarsi. 



Resembles in form the European C. castaneus, Schn., but 

 the legs are much less robust and the colour black. 



Ilah. Miyanoshita, Hakone, Kiga, Nikko, and Konose. 

 Occurs in decaying beeches. 



Corticeus gentUiSj sp. n. 



Cylindricus, elongatus, castaneus, nitidus ; antennis pedibusque con- 



coloribus. 

 L. 31 miU. 



The species differs from the last in size and colour. The 

 head rather densely and distinctly punctulate ; the thorax 

 scarcely longer than broad, more sparsely punctulate than 

 the head; the scutellum, punctures obsolete; the elytra 

 striate-punctate, with rows of intervening punctures, but the 

 sculpture is not so clear and well-marked as in C. colydioides ; 

 the pygidium, punctuation very fine and not dense. 



Ilah. Yokohama. Under the loosened bark of Zelkowa 

 Keaki, Sicb. Two examples.
