Thorax a little wider than long, rounded on the sides, a little 
wider at the base than the apex, the posterior angles rounded, 
with a small fovea near the middle of each side. Elytra of the 
width of the thorax, about three times the length, parallel-sided, 
very finely punctate, but neither so minutely nor densely as in H. 
suhvittatus. Anterior tibiae strongly tridentate. 
Long. 2^, lat. 1 line. 
169. SciTALA PALLIDULA, n.Sp. 
Sub-ovate, pale reddish-brown, sub-opaque. Head slightly 
convex, extremely minutely punctate, the clypeal suture deeply 
impressed and bisinuate, the clypeus nearly square and somewhat 
excavated and refiexed in front, with a very light emargination. 
Thorax more than twice wider than long, the anterior angles acute 
and prominent, the sides widened to near the base, the posterior 
angles rounded ; the puncturation almost invisible, the median 
line obsoletely impressed. Scutellum elongate-triangular. Elytra 
very pale testaceous, sub-nitid, sub-oval, about three times the 
length of the thorax, and finely punctate, with a callus at the 
humeral angle, and a sutural and four geminate strise on each 
elytron. Legs moderately robust, anterior tibise tridentate. 
Long. 4, lat. 2 lines. 
This should perhaps form a new genus.

the head and nearly as long, a little reflected and nearly truncate 
in front, the antennoe 10-jointed, the second and third joints 
equal, the fourth shortly lamellate, the other six largely lamellate, 
the lamellae long, curved, and of a pale yellow. Thorax twice as 
wide as long, truncate in front, rounded on the sides, wider at 
the base than apex, sub-truncate at the base, moderately hnely
