* The female differs from Klug's description in the thorax being black in 

 front and at the sides , but I have no doubt of the correctness of the identifica- 

 tion. The supposed male has a black spot in the middle of the thorax above, 

 and all the legs yellow. 



t In some specimens the antennas are entirely black, in others the extremities 

 of tbe tibiae as well as the tarsi are black, and in others the tip of the abdomen 

 is black.
