large; femora edentate ; front tibiae strongly notched near apex, the 
outer edge of the notch with a strong spine, all with two small spines at 
apex; tarsi thin, front pair of male with basal joint inflated and subspon-

Body apterous. 
The generic description is drawn up from troglodytes; in fiavipes 
some of the features are not quite the same, but they are not sufficiently 
divergent to treat the two species as generically different. The genus, 
with some slight doubt, is referred to the Ti igono tom ides , and to the 
vicinity of Dvstrichothorax.

Reddish castaneous. Head with two long set® between eyes and 
base, clypeal suture with two, and tip of labrum with four smaller ones ; 
prothorax with a long one on each side at apical third under surface 
with a few short setae ; antennae with thin set®, 
and setose pubescence ; legs setose, the set® 
sparse and longer on femora than on tibi®. 
Head distinctly longer than wide, with a 
wide shallow impression on each side between 
eyes. Antennae extending to hind cox®, first 
joint longer than second and shorter than third, 
third longest of all, the others feebly decreasing 
in length but eleventh distinctly longer than 
tenth. Prothorax about one-fourth longer than 
wide, truncate-cordate, sides finely margined 
but margins more strongly elevated at base ; 
median line finely impressed and near apex 
traversed by a feeble slightly oblique im¬ 
pression ; in places very indistinctly wrinkled. 
Elytra regularly ovate, extreme base no wider 
than base of prothorax, sides finely margined ; 
near apex with a carina on each side joined 
on to margin ; punctate-striate, siri® rather 
finely impressed, the punctures very obscure. 
Abdomen with a few punctures. Length, —

The male differs from the female in being smaller, with slightly 
longer antennas and legs, and inflated front tarsi. In suitable lights the 
whole of the head, elytra, and abdomen appear to be very finely shag¬ 
reen ed.
