margin armed with a number of ill-defined teeth. Head 

 closely and rather finely fiunctured ^ antennae short and stout; 

 eyes separated on the vertex by a distance slightly exceeding 

 the length of the two basal joints o£ the flagelluni. Thorax 

 coarsely punctured-rugose; scutellum punctured; median 

 segment irregularly longitudinally striate, with finer trans- 

 verse strice, giving a reticulate appearance, which is more 

 strongly developed on the more coarsely sculptured sides of 

 the segment. Pygidial area smooth, rather broadly trian- 

 gular. Legs slender ; comb of the fore tarsi long ; spur o£ 

 the hind tibia much shorter than the basal joint of the hind 

 tarsi. Radial cell broadly o!)liquely truncate at the apex ; 

 second and third abscissae of the radius subequal.

? . Clypeusbroadl}^ subtruncate at the apex, the apical mar- 

 gin somewhat reflexed and with two blunt teeth on each side, 

 closely and not very finely punctured. Front opaque, finely 

 punctured-rugulose, thevertex closely and not very finely punc- 

 tured. Eves separated on the vertex by a distance half as great 

 again as tiie length of the second joint of the fiagellum. Mesc- 

 notum and mesopleurge coarsely punctured-rugose; scutellum 

 strongly but not very closely punctured. Median segment 

 coarsely longitudinally striated, with finer, irregular, transverse 

 striaj between ; the sides of the segment coarsely rugose-reti- 

 culate. Abdomen shining; pygidial area triangular, shining, 

 with a few small scattered punctures. Radial cell rather broadly 

 obliquely truncate at the apex ; second abscis:-a of the radius 

 a little longer than the third, equal to the distance between 

 the recurrent nervures on the cubitus.
