Mr. F. P. Pascoe on a new Genus of Anthribide. 455 
antice contigue. Propectus brevissimum haud canaliculatum. 
Abdomen segmento quarto maximo, ultimo perparvo. 
This description is from a single specimen, and may, when 
other species are known, require to be modified. The pecu- 
liar character of the genus (which may be placed near Ceu- 
thorhynchus) lies in the antenne, the last two joints of the 
funicle apparently forming a part of a loosely-jointed club ; 
in the figure these two joints are represented as much too 
slender. 
_Diacritus pinguis. (Pl. XVIII. figs. 9a and 9 f.2.) 
D. breviter ovatus, fusco-castaneus, supra laxe pilosus; elytris basin 
versus bituberculatis, humeris rotundatis. Long. 2 lin. 
Hab. Tamatave (Madagascar). 
Shortly ovate, very convex, dark chestnut-brown, hairy, 
the hairs paler, those beneath longer and more scattered ; ros- 
trum nearly twice as long as the prothorax, ribbed at the base 
and equally slender throughout; antenne pale ferruginous ; 
prothorax transverse, gradually broader towards the base ; 
elytra level with the prothorax at the base and slightly broader 
posteriorly, striate-punctate, interstices flat, but raised towards 
the base, a round slightly elevated tubercle on the third ; 
pygidium very small; legs slightly hairy.

[Plate XVIII. fig. 10.] 
NAUSICUS. 
Caput transversum, postice constrictum, inter oculos latissimum ; 
- rostrum angustius, breviusculum ; scrobes foveiformes, infra oculos 
site. Oculi ovati, distantes. Antenne articulis 3°-8™ tenuissimis ; 
clava elongata, laxa. Prothorax transversus, carina a basi remota, 
ad latera haud producta. Hlytra subquadrata. Pedes brevius- 
culi; femora fusiformia ; tibic teretes ; tarsi articulo basali longi- 
usculo; wnguiculi dente subbasali instructi. Propectus breve. 
A well-marked genus, whose nearest affinity appears to be 
with Nessiara, from which it differs in its broad flat front, 
the small widely separated eyes, the long and very slender 
antennee inserted just below the eyes, the prothorax trans- 
verse, its carina distant from the base and not prolonged at 
the sides, &c.
