dorsal part sub-foveolate, declivity foveolate ; abdomen sessile,

 striolate in the apical part, bands silky white with a faint tinge of

MUTILLA AEIADNA. 



Female. Head, antennae, with the exception of the two first 

 joints which are rufescent, and abdomen black ; thorax and legs red, 

 body clothed with a greyish pubescence ; head slightly broader than 

 the apex of the thorax, and very rugose, sub-quadrate, eyes very 

 large, space between the hind part of the eyes and the basal angle 

 very short ; apical part of thorax slightly sloping on each side, the 

 angle sharp but not projecting, outer sides nearly straight, not 

 incised, margin hardly serrulate, basal part a little broader than the 

 apical one, posterior declivity perpendicular, serrulate on the upper 

 part and also laterally ; abdomen pyriform, second segment covered 

 with closely set, short striolae, apical part of the four intermediate 

 segments with an uninterrupted band of silky \vhite hairs, wanting 

 on the basal segment ; ventral carina of the first segment, short, 

 sharp, incised in the centre ; tibiae spinose. Length 4 mm. 



The shape of the thorax and abdomen is similar to that of

 of the median part where it is distinctly projecting in a triangular

 it is only one-half the width of the apex ; declivity truncate and 

 serrate laterally, dorsal part covered with moderately broad but
