 BRACHYLABIS NIGRA Scudder. ' 



One male. Cacao, Trece Aguas, Alta Vera Paz, April 19. 



This is the first reference, so far as I know, of this species being 

 found north of South America. 



The tarsus of the left middle leg of this specimen is deformed, having 

 the second joint aborted and the others somewhat swollen, the whole 

 tarsus a little shorter and stouter than normal. The golden luster is 

 but little noticeable in this specimen. The measurements are: Length, 

 body, without the forceps, 8 mm.; forceps, 1.75 mm.

 and posteriorly gradually and slightly narrowing, the posterior margin 

 rounded; the disk is mesially carinate longitudinally, but inconspicu- 

 ously so, and is more flattened on the posterior portion. Abdomen 

 much flattened, broadest in the middle, the lateral folds scarcely visible, 

 the last segment very slightly transverse; subgenital plate projecting 

 backward between the lower part of the forceps as a quadrate apically
