The female has much general resemblance to X. astuansy 

 but the yellow on the thorax extends down the sides, 

 beneath the wings, and the posterior margin of the vertex 

 is fringed with yellow hairs ; there is also a little on the 

 cheeks. The male I have not seen, but it is described as 

 having the labrum, the margin of the clyjDeus, and a spot 

 at the base of the clypeus, testaceous ; the thorax and 

 abdomen clothed with olive-yellow pubescence ; beneath, 

 mixed with black ; the legs with reddish-yellow pubes- 

 cence. Length of the female twelve lines ; the male rather 

 shorter.

This species is remarkable in always, apparently, having 

 the second submarginal cell obsolete ; it has been received 

 from three localities. I have examined two males and ten
