MUTILLA OPIS. 



Black, covered a brief flavescent pubescence and a few moderately 

 long greyish hairs ; antennae rufescent, apical and basal part of legs 

 and the whole of the tarsi rufescent ; thorax red, abdomen black, 

 and with two median flavescent patches on the second segment, 

 all the four apical segments fringed with dense sub-flavescent hairs, 

 not dense or short enough to form a band ; head large, quadrate, but 

 a little rounded in the posterior angles, broader than the thorax, 

 eyes large, lateral but hardly reaching the median part of the outer 

 sides which are straight, frontal part with two very distinct, small 

 tubercles above the point of insertion of antennas ; the whole head 

 is covered with closely set punctures without raised intervals ; thorax 

 sloping slightly at each side of the apex, with the anterior angles 

 sharp and projecting, sub-parallel but a little narrowed gradually 

 towards the posterior declivity, and slightly emarginate towards the 

 median part ; it is closely punctate, the punctures are slightly 

 foveolate and closely set, and the sides are serrulate from the 

 anterior angle to the bottom of the declivity ; abdomen sessile, 

 somewhat pyriform, sharply dentate at base, first segment as broad 

 at apex as the base of the second, which is nearly as broad as long, 

 and both covered with very closely set, small elongate punctures, 

 the other segments are more finely punctured, and the pygidial area 

 is finely striolate longitudinally ; ventral carina of first segment 

 laminate, sharply truncate at apex ; tibiae with a double series of 

 spines, spurs white. Length 6|- mm. 



Very closely allied to M. perse, Per. ; the head, although broad, 

 is not quite so wide, the thorax is a little more emarginate laterally, 

 the two spots on the second abdominal segment are smaller and 

 equi-distant from centre and outer margin, and the pygidium is very 

 closely striolate instead of being very finely rugose.

MUTILLA EUTERPE, 

 Plate VIII., fig. 10. 



Head, antennas, thorax and legs light ferruginous-red ; abdomen 

 black with a small elongate central white spot on the second 

 segment, third joint clothed with a silky white band ; head large, 

 wider than the thorax, quadrate, as broad as long on the vertex, 

 eyes large, lateral, reaching only the median part of the outer 

 sides, very rugose, sub-strigillate in the anterior part of the vertex,
