186 MONOGRAPH OF THE 
tuberculo parvo corniformi armato ; abdominis segmentis simplicibus ; elytris tenue 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 dise 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 ; 30, and 3c, the an- 
tenne in different positions. 
Species XXIIJ.—Pavssus Aituiops, Blanch. 
(Plate 93, fig. 6.) 
Castaneus, sub-nitidus elytris magis rufescentibus punctatis, capite ante oculos breviori, vertice 
spina tenui acuta setosa armato, antennarum clava ovali basi extus in spinam obtusam 
producto, disco subdepresso sublente puuctatissimo, tibiis gracilibus 2-calcaratis, tarsis 5-ar- 
ticulatis articulo basali minuto, prothorace vix capite latiori medio constricto, parte 
postica in medio longitudinaliter laté-impressa ; abdominis basi et metasterno castaneo- 
fulvis. Long. corp. lin. 43. 
Habitat in Nubia, D. Botta. In Mus. reg. Paris. 
Syn.— Paussus Aithiops, Blanchard in Regne An. Edit. Crochard. Ins. pl. 61, fig. 8. 
The shape of the clava of the antennee, 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; 60, the maxillary 
palpus; 6c, the antenna; 6d, the same seen sideways. 
Species XXIV.—Paussus pentirrons, Dej. 
(Plate 93, fig. 4.) 
Totus castaneo-fulvus nitidissimus ; antennarum clava brevi lata triangulari-ovata supra et infra 
disco in medio convexo, basi trunctata et in spinam obtusam extus producta; vertice 
spina erecta setigera armato ; elytris punctatis, prothorace antice lateribus dilatatis capite 
latiori in medio profunde impresso et sulco tenui longitudinali fere ad marginem anticum 
extensa ; pedibus compressis nitidis, tibiis bicalcaratis tarsorum articulo basali minuto 
abdominis segmentis simplicibus. Long. corp. lin. 4. 
Habitat in Senegallia. Mus. Dupont, Guérin, nostr., &c. 
Syn.—Platyrhopalus dentifrons, (Dej.) Westw. in Trans. Linn. Soc. xvi. p. 662, pl. 33, 
fig. 68— 70. 
The structure of the palpi of this species proves it to belong to the 
present genus, and not to Platyrhopalus, in which I had at first 
provisionally arranged it. The form of the clava of the antenne, 
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; 4d, the maxillary 
palpas ; 4c, the antenna ; * the same seen sideways; 4 d, one of the 
tarsi,
