under Lacordaire’s observation when he wrote the note * 
referring to X. confusa. If the complete division of the 
eleventh joint of the antenne is to be taken by itself as a 
sufficient specific difference, the latter species may conveniently 
be called X. confusa, Lacord., 
Xestta longipennis (Chevr., MS.), sp. n. 
Castanea ; prothorace supra transversim sat regulariterque plicato, 
lateribus irregulariter rugosis; elytris elongitis, castaneis, sub- 
opacis, vitta lata longitudinali utrinque rufo-castanea ; apicibus 
truncatis utrisque longe bispinosis; femoribus ultra medium 
modice clavatis; anternis (2) quam corpore multo brevioribus, 
articulis a septimo ad decimam apice intus angulato-productis, 
articulo tertio quam quarto duplo longiore,

Hab. Brazil. 
Very closely allied to X. vittata, Thoms., from which it 
differs by the more regular transverse rugation of the upper- 
side of the prothorax and by the relatively greater length of 
the elytra. 
Nestia globulicollis, sp. n. 
Criodion globulicolle (Chevr., MS.). 
Rufo-brunnea ; capite antennarumque basi sat dense punctatis ; 
prothorace grosse denseque et subrugose punctato, dorso medio 
plaga parva levi; lateribus rotundatis, antice et postice leviter 
constrictis ; elytris minute punctulatis, subopacis, apicibus externe 
rotundatis, prope suturam breviter truncatis, et ad suturam 
brevissime mucronatis ; antennis (¢ ) articulis a sexto apice intus 
angulatis, haud dentatis.

This species is of a dull reddish-brown colour above; the 
elytra somewhat paler in tint. The abdomen, the middle of 
the hind breast, and the femora are reddish testaceous and 
nitid. The prothorax is strongly, closely, and somewhat 
rugosely punctured, with a small smooth space on the middle 
ot the disk ; the sides are distinctly rounded in the middle. 
The elytra are coriaceous, very feebly punctulate, each of the 
minute punctures or pits bearing an exceedingly minute 
whitish seta. The first nine joints of the antenna together 
surpass by a little the middle of the elytra (the remaining joints
