does not prevent, however, from distinguishing the sculpture : the latter con- 

 sists of a moderately dense punctation and several rather shallow grooves, two 

 of which, running from the coUare backwards, end about the middle of the 

 thorax by a slight, smooth and flat expansion. Pleurae black, punctured, ex- 

 cept a smooth, shining spot in the middle; their lower part is pubescent. Scu- 

 tellum punctured above, rugose behind and finely pubescent; the pits at its 

 base are of moderate size. Abdomen pitch-black, in some specimens slightly 

 reddish below and along the hind margin of the segments; its whole surface, 

 except the base of the segments and a narrow, smooth line along the back, is 

 clothed with a whitish, appressed pubescence; under this pubescence a mode- 

 rately dense punctation is perceptible; the second (largest) segment of the ab- 

 domen hardly reaches its middle. The feet are dark brown, pubescent: the 

 base of the femora, the knees and the tarsi of the foremost pair are reddish; in 

 some specimens a reddish tinge appears at the base of the femora and on the 

 knees of the two posterior pairs. Wingn hyaline; the second transverse vein 

 forms a knee which bears a distinct stump of a vein in the middle. 

 Seven 9 specimens."
