MUTILLA ONARA, sp. JIOV. 



Long. 1 6 — 1 7 mm. 6. 



Agrees in coloration with M. Jionorata — black, with 

 the basal three segments of the abdomen red, and the third 

 segment thickly covered with pale fulvous pubescence — 

 but may be known from it by being larger, by the central 

 area on the median segment being much broader and not 

 nearly so much narrowed at the apex, and by the basal 

 half of the metapleura^ being impunctate. 



Scape of antennae shining, sparsely covered with long 

 white hair ; the flagellum with a dense microscopic pile ; 

 the third joint is slightly shorter than the fourth. Front 

 and vertex deeply rugosely reticulated ; the front broadly.in 

 the middle thickly, covered with long white hair. Clypeus 

 very smooth and shining; its sides and apex raised. Mandi- 

 bles at the base thickly covered with long, pale fulvous 

 hair ; palpi black, covered with short hair. The upper 

 edge of the pronotum has a broad band of silvery pubes- 

 cence, and is strongly rugosely reticulated ; the pleurae, 

 except above, have in the middle stout, somewhat irregular, 

 longitudinal striae. Mesonotum coarsely, irregularly, 

 rugosely punctured and reticulated, more finely and closely 

 at the base than at the apex ; the hair is long, black and 

 sparse ; there are four longitudinal furrows, the inner 

 being the shorter. Scutellum roundly convex, not much 

 raised ; rugosely punctured, sparsely covered with long 

 black hairs ; the post-scutellum rugose. Median segment 

 thickly covered with long white hair ; largely reticulated ; 

 the central area wide, in length scarcely twice the 

 width at the base; the apex slightly narrowed; the 

 apex itself with the sides oblique. Mesopleurai closely 

 rugosely punctured, covered with white hair ; the basal 

 half of the metapleur^e smooth ; the apical largely reticu- 

 lated. The sides of the mesosternum irregularly stoutly
