front furnished in the middle with a small prominence, which 
is clothed with fulvous hair, and thus appears like a small 
conical horn. Antennas pitchy, the club paler. Thorax 
about as broad as long, slightly narrowed in front of the 
middle, convex, the posterior angles rounded; the sculpture 
is of the usual character, but is much less strong than in most 
of its allies, somewhat closely rugulose punctate posteriorly, 
gradually becoming more and more asperate anteriorly, where 
on each side are five small, reflexed, sharp tubercles, placed 
obliquely in the ordinary way, the anterior one on each side 
being the anterior angle (which is not prolonged). Elytra 
scarcely broader than the thorax, two and a quarter times 
as long, closely and very strongly punctured (the punctures 
having a tendency to form lines), the intervals not raised; no 
cost®; the apex obliquely deflexed, scarcely concave, the 
apical margin much thickened and slightly reflexed, within 
the margin the surface is nearly smooth ; at the subapical 
callosity there are two tubercles, the outer one obtuse and 
scarcely raised, the inner one is well developed, acutely coni¬ 
cal, directed upwards and slightly towards the suture.

Two examples. This species was originally described from 
the island of Johanna. 
For the next species, which is a new genus of Calandrid®, 
1 propose the name Perissoderes , characterized as follows:— 
Peeissoderes, n. gen. 
Rostrum robust, rather suddenly deflexed from the base, 
very gently arcuate, swollen at the base; the antennal scrobes 
inferior, deep, elongate-ovate. First joint of the funiculus of 
the antennae short, obconic ; the second as long as broad ; 
third to sixth slightly transverse, the spongy part of the club 
nearly hidden. Thorax as long as broad, quadrate, scarcely 
narrower immediately before the anterior constriction than at 
the base; the base bisinuate, the mesial lobe acute and 
covering the scutellum. Pygidium longer than broad, de¬ 
flexed, curvilinear. Prosternum furnished with a strong post- 
coxal projection, which is emarginate posteriorly. The meso- 
and metasterna are on the same plane. 
There are only two genera, Barystethus, Lac., and Dia- 
thetes , Pascoe (Journ. Linn. Soc. 1876, xii. p. 71), which 
have the scutellum covered by the lobe of the thorax; and 
this latter has it only partially covered. In the present genus
