7. PROSOPIS TUBERCULATA, n. s. B.M. 

 Male. Length 3 lines. Black ; head and thorax deeply 



punctured, the face below the insertion of the antennae cream- 

 coloured ; scape of the antennae black, much dilated, the 

 flagellum beneath rufous. Thorax, a spot on each side of the 

 collar, the tubercles, and the tegulae anteriorly cream-coloured ; 

 the enclosed space on the metathorax below the post-scutellum 

 very rugose ; the anterior tibia in front and the tarsi ferrugi- 

 nous, the latter stained with fuscous above. Abdomen shining, 

 distinctly punctured, the third and fourth segments beneath, 

 each having at their base an elevated compressed tubercle, their 

 margin rounded ; the posterior tubercle much smaller than the 

 anterior, sometimes nearly obsolete. 



This species is very like P. signata, but differs in the follow- 

 ing particulars : the scape is much more dilated, the wings are 

 fusco-hyaline, and the recurrent nervures unite with those of the 

 second submarginal cell, which is wider than in P. signata ; the 

 abdomen has no white pubescence at the sides of the margin of 

 the basal segments, and is more strongly punctured ; the tuber- 

 cles beneath much more elevated. 

 Hab. France.
