 subtus flavis ; tarsis fusco-brunneis ; alis hyalinis, autiois, prse- 

 cipue area costali, infuscatis ; venis nigris ; clypeo apice sub- 

 truncato ; sternito secundo basi elevato-tuberculato, 



Loug. 10 mm. 



^ . Clypeus closely microscopically punctured, with 

 larger scattered punctures, with very delicate close-lying 

 pubescence at the base, the apex subtruncate, scarcely emar- 

 ginate. Front coarsely and rather closely punctured, vertex 

 coarsely punctured-rugose. Thorax and median segment 

 coarsely punctured-rugose ; tegul?e very coarsely punctured. 

 First tergite very coarsely punctured, second much more finely 

 and sparsely punctured ; the apical margins of tergites 3-6

 strongly, but not very closely punctured, raised and sub- 

 tuberculate at the base. The first abdominal segment is

 venis nigris ; clypeo apice late emarginato ; sternito secundo 

 basi fortiter elevato-tuberculato.

(^ . Clypeus closely micro- cojiically punctured, with 

 sparse larger punctures intermingled, the apex widely, but 

 not very deeply emarginate. Head coarsely punctured,

 low arched carina above the anterior ocellus. Thorax and 

 tegulae very coarsely punctured ; median segment punctured- 

 rugose. First tergite broad, very coarsely punctured ; 

 second much more finely punctured, shining between the 

 punctures ; second sternite very strongly raised and bluntly
