MUTILLA PAECA. 



Female. Black, with the vertex of the head and dorsal part of 

 thorax ferruginous or ferruginous red, spots and band of abdomen 

 pale-yellow ; head broader than the thorax, sub-quadrate, truncate 

 behind, with the posterior angles moderately rounded, eyes small, 

 situated much forward, sub-scrobiculate, with the intervals linear in 

 the posterior part, hardly pubescent, and set with moderately dense 

 hairs ; thorax short, broad, nearly truncate at apex, very slightly 

 incised, almost straight laterally, basal part very slightly broader 

 than the apical one, declivity perpendicular, and upper margin dis- 

 tinctly dentate, disk with five straight median carinae, two sloping 

 ones on each side of the five median ones and one or two indistinct 

 lateral ones ; abdomen sub-sessile, second abdominal segments 

 striolate, spots and band as in the two preceding species, but 

 pale-yellow instead of silvery white ; ventral carina sharply denti- 

 form at apex ; intermediate segments fringed with dense, sub- 

 flavescent hairs underneath ; tibiae with a double row of spines. 

 Length 12-16^ mm. 



Allied to M. zulu, Kohl, but the head is broader in proportion to 

 the width of the thorax, the longitudinal carinae of which are more 

 numerous, the abdomen is more inflated, and there is only a few 

 lateral white hairs on the edge of the second segment instead of a 

 narrow band. 



Hab. Cape Colony (Prince Albert, Worcester). 



MUTILLA AGAVE. 



Female. Black, with the dorsal part of the thorax ferruginous, 

 spots on the abdominal segments silvery white ; head clothed with 

 a sparse, whitish pubescence, scrobiculate, the intervals raised and 

 longitudinal in the posterior central part, as broad as the thorax, 

 subquadrate, eyes set very forward ; thorax nearly parallel, but 

 emarginate laterally for about one-third of the length, truncate 

 perpendicularly behind, the top of the declivity denticulate, the 

 disk scrobiculate but with the intervals in the shape of longi- 

 tudinal, slightly undulating, carinae ; abdomen subsessile, second 

 segment covered with longitudinal raised lines ; the basal segment 

 and also the third, fourth, and fifth with a central, small white 

 patch, second segment also with a similar central apical patch and 

 having also an ovate patch on each side nearer to the apex than to 

 the base ; ventral carina of first segment incised at about the 

 median part, truncate and sharp at apex, intermediate segments 

 fringed \vith dense, greyish hairs underneath ; tibiae with a double 

 series of spines. Length 10^-11 mm.
