wide transverse dark band across its base ; the elytra very 

 faintly punctulato, tiie punctures most visible form a line 

 close to the suture, a dark band occupies the external 

 martjin-?, but leavt-s the extremely narrow rim pale ; the 

 antennae — four basal joints reddish, the others int'uscate ; the 

 legs reddish or brownish yellow. When the antenn;T3 are 

 stretched out the second joint does not reach beyond the rim 

 of the thorax.

edge like the intermediate tibiae figured in this paper for 

 Ischnodactylus loripes. This form of tibije has, however, in

 my specimens, but the structure enables the tibia, in a state of 

 repose or in a state of simulating death, to be brought closely 

 on to the femur which fits into it. 



Hab. Nagasaki and Kioto. Occurs under damp decaying 

 leaves in early spring.
