bluntly conical. The clypeus, labrum, mandibles, except 

 their apex, and the palpi are yellowish-white : the occiput 

 margined distinctly. Thorax black, the mesonotum 

 obscurely punctured, more strongly on the middle lobe, 

 which is widely and deeply furrowed down the middle ; 

 thickly covered with short, black hair. Scutellum 

 pyramidal, sparsely covered with long, black hair ; the 

 apex with a long, oblique slope ; the space between the 

 cenchri depressed ; the part behind it broadly raised. 

 Propleurse widely and deeply depressed in the middle, 

 where they are jfinely aciculated ; above there is a wide, 

 deep, curved depression, narrowed at the base. Meso- 

 pleurae bearing large, deep, distinctly separated punctures, 

 which are more numerous on the lower than on the upper 

 side ; on the lower side, next to the sternum, is a wide 

 and deep furrow clearly separating the sternum from the 

 pleurae ; the edges of the sternum are margined and end 

 at the apex in large, stout, somewhat triangular, teeth, 

 which are whitish- testaceous at the apex and project 

 obliquely. The four front legs are yellowish-testaceous ; 

 the middle tibiae and tarsi have a fulvous tinge ; the fore 

 coxae are black, testaceous at the apex ; the middle coxae 

 are pale yellowish, broadly black at the base ; the hinder 

 femora and tibiae are dark fulvous-testaceous, their coxae 

 somewhat paler, the tarsi pale yellowish, more fulvous at 

 the base. Wings fulvo-hyaline, the costa and stigma 

 fulvous, the second cubital cellule is not much more than 

 one-half the length of the third ; it receives the recurrent 

 nervure shortly before the middle ; the second recurrent 

 nervure is received in the apical fourth. Abdomen rufo- 

 testaceous, paler beneath.
