Mr. F. P. Pascoe on Spherion and Mallocera. 479 
Spherion suturale. 
S. leete rufo-castaneum, nitidum ; elytris testaceis, sutura spinisque 
nigtis ; antennis, scapo excepto, tibiis tarsisque nigris. 
Hab. Brazil. 
Head, prothorax, femora, and body beneath bright glossy 
reddish chestnut ; elytra testaceous, the suture and apical spines 
black; prothorax subcylindrical, the disk with four obtuse tu- 
bercles; elytra finely punctured, with three scarcely apparent 
pale lines on each; antennz, except the scape, tibie, and tarsi, 
dull black. Length 10 lines. 
Resembles in general coloration S. ¢erminatum, Perroud, but 
with black antenne, suture, tibie, &c., and the prothorax en- 
tirely different in form, and without the central tubercle ; above 
all, with the posterior femora nearly linear, as in Hlaphidion. 
Spherion geniculatum. 
S. testaceum, nitidum ; capite prothoraceque castaneis, hoc oblongo- 
ovato ; disco transversim plicato ; femoribus apice nigris. 
Hab. Brazil. 
Testaceous, shining; head and prothorax reddish chestnut, 
the latter oblong ovate, without spines or tubercles, finely plicate 
across the disk; elytra with small distant punctures, the suture 
near the apex and spines black; body beneath pale chestnut ; 
femora with their apices glossy black ; antennze pale testaceous. 
Length 7 lines. 
Spherion plicicolle, Germ., its nearest ally, has a broad pro- 
thorax, scarcely shining, with much coarser sculpture, the punc-_ 
tures on the base of the elytra larger and crowded together, and 
the femora nearly unicolorous. 
Merrurirtvs. 
Caput inter antennas projectum. 
Prothorax subdepressus. 
Tibie compress, posticee apice haud spinosie. 
The compressed tibie, which are strengthened by a strong 
ridge on each side for their whole length, and the absence of a 
true spine to the hinder pair (replaced, however, by a broad 
angular process) cut off this genus from all its allies. The 
head is very short, and between the bases of the antennz there 
is a prominent roll, formed apparently by the antennary tubers, 
which are otherwise obsolete; the antennz are longer than the 
body, fimbriated beneath, the third, fourth, and fifth joints 
deeply grooved, and they are also spined at the apex; the pro- 
thorax is slightly transverse, obscurely tuberculate on the disk, 
the sides projecting into a short spine nearly in the middle ; the
