484 Mr. F. P. Pascoe on Spherion and Mallocera. 
The position of the following genus must for the present be 
considered doubtful. 
ALCYOoPIS. 
Caput valde exsertum ; collo constricto. 
Antenne mutice; tuberibus antenniferis validis, intus productis, 
basi contiguis. 
Prothorax elongatus, cylindricus, irregularis. 
Mesosternum antice productum. 
Femora clavata. 
I have received the species constituting the type of this genus 
under the name of “ Spherion cyanipenne, Serv.” But it is not 
that insect, nor can it be regarded as belonging to Spherion at 
all in any sense, its head constricted behind the eyes giving it 
the aspect of a Leptura-form, and especially, if also we regard its 
colour, of Rhamnusium salicis ; it has, however, entirely rounded 
anterior acetabula, and globose coxee. The head is very short in 
front, the antennary tubers so projecting as to give that part of 
it a vertical direction; the scape is pyriform, the third joint the 
longest, and the fourth shorter than the fifth ; the eye is broadly 
emarginate, the lower lobe large and prominent, the upper small 
and remote from its fellow on the vertex; the palpi have the 
terminal joint triangular ; the prothorax is broader behind, its 
length half as much again as its breadth; the elytra are flattish, 
and nearly parallel at the sides, the apices each terminating in a 
median point; the femora are rather abruptly clavate, and the 
posterior and intermediate are equal and a little longer than 
the anterior ; the mesosternum is strongly produced. 
Alcyopis cyanontera. 
A, flavo-castanea, nitidissima ; elytris lete cyaneis. 
Hab. Brazil. 
Bright yellowish chestnut, very glossy, nearly glabrous ; head 
sparsely and finely punctured; prothorax impunctate, deeply 
and broadly constricted anteriorly ; the disk behind the constric- 
tion with five prominent tubercles—one anterior and median, 
the two external prolonged beneath at the side; scutellum semi- 
circular; elytra rich blue, very glossy, minutely and irregularly 
punctured, each apex terminating in a short median spine ; legs 
and antennz with scattered hairs, the latter rather longer than 
the body; sterna ferruginous; abdomen blackish. Length 
10 lines.
