considerably wider than strife, rather strongly punctate, neither 

 ridged nor alternately elevated. Three intermediate segments of 

 abdomen drawn backwards at sides, but especially the 2nd. 

 Femora less strongly dentate than usual, the posterior terminating 

 level with apex of abdomen; claw-joint exserted for about half its 

 length. Length 2 J, rostrum 1; width 1^ mm.

I have six specimens under examination, in no two of which 

 are the scales alike. On the head there is usually a transverse 

 patch of dark scales, more or less triangularly encroached upon 

 by the basal scales; these are usually white, but on one specimen 

 are decidedly yellow. Of one specimen the disc of the prothorax 

 is entirely covered with dark chocolate-brown scales except for a 

 longitudinal spot at the base; in others there are numerous spots 

 both at the base and apex as well as on the sides. On the elytra 

 the darker scales usually prevail, and there is generally a wide 

 basal unspotted space with paler scales, with sometimes also a 

 somewhat similar but feebler space towards the apex; the pale 

 spots may be either transverse or longitudinal and united moi'e 

 or less angularly together or solitary. 



Lyb^eba concinna, n.sp. 



Black; the elytra sometimes testaceous-red or very dark red; 

 rostrum, antennae and legs red. Head with yellowish-red or red 

 scales; eyes margined with whitish scales; rostrum with whitish 

 scales to antennae. Prothorax and elytra variegated with whitish 

 and red or yellowish-red scales, the spots of both colours variable 

 both in size and extent, but never very large. Under surface 

 and legs rather densely clothed, the scales having a very slight 

 pinkish tinge. 



Rostrum parallel-sided and feebly ridged to antennae ; in ^ 

 punctate and slightly diminishing in width to apex; in ^ impunc- 

 tate and strongly diminishing to apex. Scape in both sexes 

 shorter than funicle ; in ^ inserted two-fifths from apex of 

 rostrum and just passing apex; in 9 inserted in exact middle and
