 broader in the hind tibiae. Head seen from before as high 

 as broad, eyes not much raised above vertex, their vertical 

 diameter a little shorter than genae, vertex about two- thirds 

 broader than an eye, first joint of antennae as long as 

 breadth of vertex, narrowed at base, its exteriör margin 

 straight, the interiör margin rounded, more so toward base, 

 second joint about four times as long as first, third subequal 

 in lengtli to second, rostrum reaching base of venter, first 

 two joints of equal length, third slightly shorter than second 

 and distinctly longer than fourth. Pronotum with arcuately 

 sinuate lateral margins, basal margin broadl}^ and rather 

 deeply bisinuate, the disc thickly punctate, excepting the 

 calli which are separated by a posteriorly foveately deepened 

 impression. Scutellum rather flat, broadly subimpressed in 

 its anterior half, punctulate, rather longly erectly pilose. 

 Corium and clavus sparsely erectly pilose, thickly punctulate 

 except in the opaque areas, cuneus more than twice as long 

 as broad. Venter pubescent, male genital claspers slender,

This and the following species do not seem to be nearly

Cylapus labeculosus n. sp. — Above (except vertex and

 subglabrous. Head påle yellow variegated with fuscous, its 

 blackish shining neck with two påle yellow vittae; seen from 

 before the head is broader than high, eyes very large and 

 prominent, but moderately raised above the vertex, their 

 vertical diameter slightly longer than genae, vertex distinctly 

 narrower than an eye, the clypeal prominenence distinct, the 

 keel separating juga from genae rather strongly curved, the 

 curve turning its convexity backwards, antennae fuscous- 

 black, first joint dingy ochraceous with whitish base, as 

 long as width of vertex, subparallel from apex to middle, 

 then narrowed toward base, its exteriör margin straight, 

 interiör margin slightly rounded, second joint paler toward 

 base, considerably longer than second, rostrum fuscous-black,
