This interesting species will not enter into either of the five groups 
of the genus proposed by Mr. MacLeay (see p. 103 ante). The head 
is black, with the deeply cleft clypeus and antennae castaneous, it is 
clothed on the disc with fulvous hairs. The pronotum has the sides 
nearly straight, the hind part being much broader than the anterior, 
which has an elevated tubercle in the middle. The disc is very 
irregularly punctured, with a slightly raised line of punctures down 
the middle. The disc is black, with the sides of a pitchy red, tinged 
with purple. The elytra are broader at the base than the hind part 
of the pronotum; they are very flat on the disc, the extreme 
lateral margins being, in fact, slightly elevated, and they become 
gradually narrowed from the base, the apex of the suture not being 
spined. They are very strongly variolose on the disc, the punctures 
being largest and most irregular before the middle. They are of 
the same colour as the sides of the pronotum. The legs are castaneous 
and very long. The anterior tibiae in the male, (I have not seen the 
female,) are externally bidentate, the middle tibiae spurred beyond 
the middle, and the hind tibiae, with the apical portion on the inside, 
dilated. The mesosternum (fig. 2 a) is not advanced; the maxillae 
have the inner lobe quite simple (fig. 2 b) ; and the mentum (fig. 2 c) 
is broadest and emarginate in front. The abdomen of the male is 
channeled down the middle beneath. 
Schizorhina plumigera. (Plate 32, fig. 4.) 
Syn. Ceionia plumigera^ Gory and Perch, op. cit. No. 10. 
This is another anomalous species, which, from the form of the 
clypeus, must be referred to Schizorhina, from all the previously 
known types of which, however, it differs, both in form and in 
the singular clothing of hairs on the inside of the hind tarsi. The 
body is deflexed at each end, the clypeus deeply bifid, the meso¬ 
sternum porrected and acute, the pronotum with two, and the elytra 
with four, longitudinal carinse. The head is of a black colour, 
pitchy in front, the antennae pitchy black, the pronotum clothed 
with very fine greenish-grey pile, with the sides and the two costm 
shining black: the elytra are also similarly coloured with the 
costae and sides black, the latter with the spots and apex white; 
there are also two white spots on the podex above. The body is 
black beneath with white transverse lines (interrupted in the
