Corpus supra opaciim, plaga media elytrorum polita; autennte clava depressa quasi 5-artie\ilata; palpi
masillares articulo secundo fere rotundato depresso; labiales 3-articulat i articulo tertio majori subovali apice subt

This sub-gcnus was proposed, in the Proceedings of the Entomological Society on the 4t h of August , 1845,
for a species captured in Indi a by Mr. Benson, which agreed in general characters with Cemioderns Ufaseiatus of
Kollar, but differing f rom it in characters which do not seem to have more than subgeneric importance. Eor
these two insects the generic name of Melauopsi lus was proposed by me, the name of Ceratoderus being retained
as that of the sub-genus of C. Ufaseiatus, and a new subgeneric name, " iilerismoderus," proposed for M. Bensoni.

Captured by the late Mr . Benson under a brick near the river Ganges, about fifty miles below Cawnpore, in

and Saharnnpore.

The structure of the antennie (the club of which is not so apparently 5-jointed as in L. Gorii, Westw. Arc.
E n t . pi. LVI I I , fig. 3, a single transverse deep impression only existing), and the difli'crent form of the thorax,
lead me to regard this insect as specifically distinct from the type of the genus of which I have now seen a considerable
number of specimens, one of which (now in the Hopeian Collection) was kindly presented to me by
t h e late Herr Westermann, of Copenhagen.

The discovery of a species of this remarkable genus in the South of Af r ica, difll'ering i n certain particulars from
t h e Sierra Leone tjq)e, is ver y interest ing, and lias enabled me, by an examination of the organs of the mouth, to
establish the relationship of the genus with the Panssid®, disputed by Dr. Gerstaecker. The mandibles (fig. 1 c)
are sickle-shaped, witli a small tooth in the middle of the inner margin, and a slender basal lobe. The maxilla;
(fig. I d) arc very thin and horny, curved at the tip and bidentate, with 4-jointed maxillary palpi, the first joint
lieing very short, the second very large and inflated, and the third and fourth very small. The mcntum (fig. le)
is straight in the middle of its front margin, and the lateral angles prominent; the labium is large, flat, rather
transverse, with the middle of the fore margi n produced and rounded; the labial palpi are robust, rising from a
basal scape, with the two basal joints short, the third thick, elongate, oval, and rather acuminated at the tip
(fig. 1 e). The bead is semiglobose in front, and the arrangement for disposing of the antennie when at rest is
remarkably interesting. In the front of the face are two oval depressions, separated by a slender raised mesial
l i n e ; the basal joint of each of the antennaj is fixed at the outer upper part of these depressions, into which it
shuts like a valve ; when so shut, the large clava of the antenna; falls closely upon it, the whole scarcely standing
off f rom the surñice of the head. Eig. 1 a shews the head and prothorax, seen laterally, with one of the antennie
a t rest in front of the kidney-shaped eye. lu fig. 1 h the left antenna is opened out fi-om the depression, whilst
t h e right antenna is laid at rest, at which time the small connecting joint is brought into contact with the small
mesial ridge above mentioned. The prothorax is not so short and transverse as in II. buceplialus, and the furcate
impression on the face is wanting.
