MONOGRAPH OF THE 
tuberculo pavvo corniformi arraato ; abdominis segmentis simplicibus ; elytris tcnue punc- 
tatis. Long. corp. lin. 3. 
Habitat in Sierra Leona, D. Morgan. In Mus. Britann. 
This species is closely allied to P. armatus, from which its small 
size and more strongly punctate disc at once distinguish it. A 
single specimen is contained in the British Museum collection, pre¬ 
sented by the Rev. Mr. Morgan. 
Fig 3 a represents the head seen sideways ; 3 and 3 c, the an- 
tennse in different positions. 
Species XXIll.—P aussus ^Ethiops, Blanch, 
(Plate 93, 6g. 6.) 
Castaneus, sub-uitidus elytris magis rufescentibus punctatis, capite ante oculos breviori, vertice 
spina tenui acuta setosa armato, antennarum clava ovali basi extus in spinam obtusam 
product©, disco subdepresso sublente puoctatissimo, tibiis gracilibus 2-calcarati8, tarsis 5-ar- 
ticulatia articulo basal! minuto, prothorace vix capite latiori medio constricto, parte 
postica in medio longitudinaliter late-impressa; abdominis basi et metasterno castaneo- 
fulvis. Long, corp, lin. 4^, 
Habitat in Nubia, D. Botta. In Mus. reg. Paris.

The shape of the clava of the antennas, and the habitat of the 
species, distinguish it from the other species with the head cor- 
nuted between the eyes. 
Fig. 6 a represents the head seen sideways; 6 6, the maxillary 
palpus ; 6 c, the antenna; 6 rf, the same seen sideways. 
Species XXIV.— Paussus dentifrons, Dej, 
(Plate 93, fig, 4 ) 
Totus castaneo-fulvus nitidissimus; antennarum clava brevilata triangulari-ovata supra et iiifia 
disco in medio convex©, basi trunctata ct in spinam obtusam extus producta; vertice 
spina erecta setigera armato ; elytris punctatis, prothorace antico lateribus dilatatis capite 
latiori in medio profunde impresso et sulco tenui iongitudinali fere ad marglnem anlicum 
extensa ; pedibus coinpressis nitidis, tibiis bicalcaratis tarsormn articulo basali minuto 
abdominis segmentis simplicibus. Long. corp. lin. 4. 
Habitat in Senegallia. Mus. Dupont, Guerin, nostr., &c. 
^Yn,—Platyrhopalus dentifrons, (Dej.) Westw, in Trans. Linn. Soc. xvi. p. 662, pi. 33, 
fig. 68-70. ^ ^ 
The structure oi the palpi of this species proves it to belong to the 
present genus, and not to Platyx'hopalus, in which I had at first 
provisionally arranged it. The form of the clava of the antennm, 
and the very glossy surface of the body, separate it from the other 
cornuted species of the genus. 
Fig. 4a represents the head seen sideways; 4 3, the maxillary 
palpas; 4 c, the antenna ; * the same seen sideways; 4 d, one of the 
tarsi.
