MUTILLA THEMIS. 



Female. Black, with the dorsal and lateral part of thorax red ; 

 head narrow, long, scrobiculate with the intervals carinate and 

 undulating, as broad as the thorax at apex, posterior angles a 

 little rounded, eyes large, very convex ; it is clothed with a sparse, 

 whitish pubescence and moderately dense, long black hairs ; thorax 

 elongate, narrow, truncate at apex, deeply incised laterally in the 

 median part with the angles of the incision dentate, declivity 

 sloping, the whole of the dorsal part covered with deep scrobes, the 

 intervals of which form longitudinal, wavy carinaB reaching from 

 apex to base ; abdomen sub-sessile, sub-pyriform, second segment 

 striate irregularly, basal joint short and without any band or spot, 

 second joint with two sub-ovate white patches, not quite in the 

 middle, but equidistant from the centre of the disk and the outer 

 margin, third segment with a broad white band, broadly interrupted 

 in the centre, apical segment with white pubescent hairs ; ventral 

 carina short, acute, truncate at both ends and with three indistinct 

 serrations ; tibiae with two spines. Length 15 mm. 



Eesembles very much M. sycorax, and might be easily mistaken 

 for it ; the abdomen however is more pyriform, the mesonotum is 

 black, the ventral carina of the first joint is not sharply dentate, 

 and the ridge on the ventral part of the second joint does not end in 

 a tooth ; the punctures on the second segment are much more 

 elongate and the intervals much raised and sub-linear. 



Male. Black, clothed with grey and black hairs and with white
