for the remaining part ; abdomen covered with very closely set round 

 punctures, first joint with a short, slender stalk and produced in a 

 large node and having a thin, transverse fringe of sub-erect pallid 

 hairs at about the median part, second joint very swollen and with 

 an apical fringe of long, dense, decumbent whitish hairs, third 

 segment with a similar fringe ; ventral carina short, sharp, truncate 

 at both ends ; tibias without any spine. Length 7 mm.

This species is easily recognised by the short stalk of the basal 

 abdominal joint, which is swollen into a large node resembling that 

 of a male Apterogyna. 



MUTILLA BYBLIS. 



Anterior part of the head and abdomen black, posterior part of the 

 head, neck, upper part of thorax, and base of the first abdominal 

 segment, red, shining, antennas and legs infuscate ; head as broad as 

 the base of the prothorax, sub-quadrate, slightly attenuate laterally 

 behind, very rugose, villose and covered with a very short silvery 

 pubescence ; lateral part of prothorax slightly and bluntly denticulate ; 

 metathorax elongated in the shape of a truncate pyramid, covered 

 with deep, closely set foveas, the intervals of which are sub-tubercu- 

 late, mesothorax without any longitudinal groove ; first segment of 

 abdomen long, conspicuously petiolate, spinose laterally at base, 

 ventral carina sharp and truncate at both ends, covered like the 

 second segment with small, elongated, closely set punctures, the 

 intervals of which are moderately raised and sharp, upper apical 

 margin with a broad band of silky white hairs, second segment 

 inflated and with a moderately broad white band, third segment also 

 with a similar band, these two bands are replaced underneath by a 

 less dense and narrower greyish white band, the fourth segment has 

 also a similar fringe ; intermediate and posterior tibiae with a double 

 series of spines ; abdomen and legs, tarsi included, set with dense, 

 long silvery white hairs. The wings are wanting in the only speci- 

 men I have been able to examine. Length 7-11 mm. 



The shape of the prothorax is nearly identical with that of the 

 same sex of M. galanthis, and the sculpture of the abdomen is similar, 

 but the first abdominal segment is longer, and the foveae of the meta- 

 thorax are deeper and broader.
