Head and prothoracic lobes dark violet or blue, changing 

 with the incidence of the light ; mesonotum green or blue ; 

 abdomen dark violet, in some lights with a coppery reflection, 

 with basal segmental silvery white lateral spots, which form 

 a continuous band on the basal segments, no silvery marks

 below ; wing scales dark ; second marginal cell very slightly 

 longer than the second posterior cell ; claws simple in the

 a large reticulated area bearing minute setae ; at the side of 

 this a small setose rounded lobe; scales on the outer half of 

 the inner margin, broad, dense, with pointed tips, all straight ; 

 a small tuft of setae at the tip within. Clasper moderate, slen-
