136 Mr. Cameron on 



MUTILLA PULCHERINA, Smith. 



Head and thorax ferruginous, the antennae, mandibles, 

 legs and abdomen black : a small, somewhat triangular, spot 

 on the basal segment, a broad band, dilated roundly in the 

 middle at the apex, on the base of the second ; the third 

 segment entering a broad band in the fourth (the latter two 

 interrupted in the middle), and a fringe on the apical 

 abdominal segments, golden fulvous. Antennas short, thick ; 

 the third joint about one-half longer than the fourth, 

 and shorter than the fourth and fifth united. Head 

 narrower than the thorax, very coarsely rugosely punctured ; 

 the antennal tubercles shining, impunctate ; eyes small, 

 oval, vertex convex, not much elevated above the eyes ; 

 the long hair on the vertex blackish ; on front and oral 

 region fulvous. Thorax coarsely longitudinally, irregularly 

 strialate ; but the furrows are not continuous ; mesopleune 

 shining, impunctate. The sides become gradually and 

 slightly narrowed from base to apex ; a little before the 

 middle there is a stout tooth ; and there is a blunt tubercle 

 a little beyond the middle. Abdomen distinctly longer 

 than the head and thorax united, subessile ; pygidial area 

 apparently strongly transversely aciculate ; the second 

 ventral segment very coarsely transversely punctured. 

 Legs (including the tarsi) densely covered with long fulvous 

 hair ; the femora coarsely punctured ; the calcaria pale 

 testaceous. 



The band on the second abdominal segment varies, and 

 may become broken up into three rounded spots. 



M. Aurifex is probably a variety ; but the description is 

 imperfect.
