a lai-f^c, elongate depression in the middle ; the keel is 

 straight throughout. The sides of the hypopygium are 

 raised on the apical half, the raised part depressed at the 

 base ; in the centre at the apex are two shorter keels, 

 also dilated at the apex. 



Comes near to Ll.perdita and J/, cressida ; the former 

 may be known from it by having the keel on the petiole 

 dilated at the apex and by having the four apical 

 abdominal segments black ; the latter is more stoutly built 

 and may be known by the second cubital cellule being 

 clearly longer above than the third and by the median 

 segment bulging out in the middle. 



MUTILLA ANTERA, Sp. nov. 



Nigra, abdoniine fcrruginco, basi apiccque nigris, basi 

 scutelli medio canaliculato ; alis violaceis. $ . 



Long. 20 mm. 



Belongs to the group of M. dimidiata Lep., having the 

 scutellum raised and the abdomen for the greater part 

 ferruginous ; but may be easily known by the base of the 

 scutellum having a wide and deep depression in the 

 middle. 



Scape of the antennae covered with long white hair ; 

 the flagellum with a pale pile ; the third and fourth joints 

 almost equal in length, but, if either, the third is the 

 shorter. Head coarsely rugosely punctured, a large smooth 

 space on either side behind the ocelli. Clypeus broadly pro- 

 jecting in the middle, its apex slightly waved. Mandibles 

 thickly covered with long, pale fulvous hair at the base ; 

 the lower tooth is much shorter and more rounded than the 

 upper ; the palpi black. Pronotum rugosely punctured, 

 thickly covered with long fuscous hair ; the propleurse at the 

 base rugosely punctured ; the middle depression bearing 

 seven stout, distinctly separated keels ; the apex is smooth.
