38 Mr. T. Vernon Wollaston on the 
wood in a neglected out-house. I believe, therefore, that 
its mode of life is very similar to that of Pentarthrum 
and Mesoxenus ; and if this be the case, I am the less 
sui-prised that Mr. Le^ds should have detected a second 
representative of the genus in so distant a region as the 
Japanese archijielago.

The present Hexarthrum very closely resembles the 
H. capitulum, which has been observed hitherto only in 
Madeira ; it is, however (judging from the single example 
now before me), a little smaller and darker, its rostrum is 
not quite so thickened, its limbs are (if anything) even 
more abbre\aated still, its elytra (which, when viewed 
beneath a high magnifying power, are not quite so appre- 
ciably asperate) have their stride deeper and their punc- 
tures somewhat larger ; and its first and second abdominal 
segments are not quite so distinctly separated from each 
other by a sutural line. The unique example from 
which the diagnosis has been compiled was captured by 
Mr. Lewis at Hiogo, in the island of Nipon.
