 lemale ; epistoma very small, somewhat long-triangular with rounded 

 upper angle, while the cheeks are very large and about equal in width 

 through the whole length. Frontal triangle almost in level o{ the eye- 

 margins, triangular, produced very narrowly above, densely' covered 

 with pale yellowish or pale reddish yellow tomentum which becomes 

 blackish above the middle, this blackish tinge forming an indefinite 

 cross-band which is continued with the blackened part of the eyes, 

 while the tomentum on the lower part cross the antennal bases from 

 eye to eye is dark brown, this colour forming a rather conspicuous 

 cross- band and extending a little down the sidemargins of the face. 

 Back of the head with only a very short pale yellowish postocular

 near the eye-angles, until the upper third of the head, whence a line 

 of long forwardly curved pale yellowish hairs extends to the vertex, 

 and intermixed with them are some similar but black hairs, but behind 

 the vertex there is dense shorter whitish pubescence which more or

 the sucker-flaps, pale yellowish ; basal joint cylindrical and as long as 

 the second joint, covered with a greyish tomentum except about its 

 tip and closed with long whitish pubescence ; second joint thick oval 

 almost globular, being only one and a third times as long as broad, 

 and thickened apically so as to become rather club-shaped with a very

 pubescence on the end joint somewhat long, which is intermixed with
