The

following descriptions and synoptic keys have been prepared inorder that

names may

be available for several undescribed species of Panscopusin the United States National

Museum

collection, in- cluding

two

submitted for identification by

W. W.

Baker, of the Division of

Truck Crop

and

Garden

Insect Investigations, United States Bureau of

Entomology

andPlant Quarantine.

Panscopus

may

be briefly characterized as a group of North

American

scarred-snout weevils with a prothoracic ocular lobe and a rounded to narrowly elliptic scale in each serial puncture of the elytra.

The

shapeof the serial scale varies considerably, butin only one species {altcr'natus Schaefifer) does it

become

hairlike. In one subgenus {Para panscopus) there is a well-defined double

row

of spines at the apex of thehind tibiae enclosing an oblique, narrowly fusiform,subglabrousarea (corbellaryplate,fig.2,a). All the species are flightless,and

some

of

them

doubtless are in the nature of geo- graphic forms; but their exact status cannot be determined with certainty at present.

The

rostral length of the descriptions is the straight-line distance between the tips of the closed mandibles and the pointwheretheuppersurface of the rostrum meetsthe globular basal portion of the head.

The

terms anterior, posterior, dorsal,and ventral, as applied to the surfaces and edges of the leg segments, indicatetherelativepositionsthat

would

beassumed bythese surfaces ifthelegwere extendedⁱⁿastraighthorizontalline at rightanglesto the longitudinal axis of the body.
