I am not siure that this species might not properly be re- 
garded as the type of a new genus allied to Liparetrus. its 
long elytra almost covering the propygidium in both sexes 
and its depressed elongate appearance, together with its pecu- 
liar sculpture and vestiture, render it very isolated in this 
genus. I cannot, however, discover any definite structural 
character that is not paralleled in some unquestionable Lipare- 
frus, unless it be the abdominal character of the male (i.e., 
the pygidium folded under so as to narrow, as if crowded toge- 
ther, the ventral segments on the middle line). This, how- 
ever, does not seem sufficient to justify the creation of a new 
genus. It should be noted that in both sexes the front tarsi 
are remarkably short, being (even in the male) less than half 
as long as the hind tarsi : and that the erect hairs on the 
elytra are disposed in longitudinal rows.

I have seen two specimens of this insect, and do not find 
any defined sexual characters among them. Thev are pro- 
bably females, and it is not unlikely that the male has some 
distinctive character in the ventral segments and clvpeus. 
The species described above is very different from all its 
allies (infer alia, by the very close, strong, subrugulose punc- 
turation of its elvtra, and its colouring), and mav safelv be
