arese ; in forticarinata the basal central one is triangular at 

 the base, the apex transverse ; in the present species it is 

 shorter, broader and rounded at the base, while there 

 is, at its apex, an intermediate area which is absent in 

 forticarinata, the latter too having the pleurse more 

 strongly punctured. 



Agathis PERONATA, sp. nov. 



Long. 9-10 mm. $ . 



Resembles closely A. forticarinata, from which it differs 

 by the two clouds in the wings being fainter, by the hinder 

 tibiae being almost entirely black, by the median segment 

 being stoutly transversely striated, and by the central basal 

 area being transverse, not triangular, at the base; by the 

 furrows on the mesopleurse being wider, deeper, and more 

 strongly crenulated ; by the three keels on the metapleural 

 depression being more widely separated, especially in the 

 upper two, which are more widely separated than are the 

 middle and lower, while in A. forticarinata the three are 

 separated by almost the same distance. 



Antennae longer than the body, black ; the scape 

 rufous beneath, thicky covered with longish, pale hairs ; the 

 flagellum thickly with short, stiff, black hair. Face shining, 

 indistinctly punctured; thickly covered with short, black 

 hair ; the clypeus more strongly and distinctly punctured 

 than the face, and clothed like it; the palpi covered with 

 long, pale hair ; the vertex and occiput thickly covered with 

 longish, fuscous hair ; the front shining, bare, not greatly de- 

 pressed. Middle lobe of the mesonotum greatly raised above 

 the lateral ; strongly punctured, depressed in the middle ; 

 the depression raised in the middle ; the raised part being 

 more closely punctured, and with the punctures smaller 

 than they are on the sides. Scutellum strongly punctured ; 

 a stout, curved keel on its apex ; the depression at its base
