 the head punctured, slightly dilated behind the eyes ; the sutures on 

 vertex shallow. Mesonotum with a distinct punctation; pleurae 

 coarsely rugosely punctured. Transverse radial nervure interstitial or 

 nearly so ; the second recurrent nervure at a distance from the trans- 

 verse cubital. Spurs short. $ . 



Length 10 mm. 



The head in my specimen is entirely black; but, 

 according to Konow, it may bear two small white 

 spots. 



A well-marked species from the coarsely punctured
