(Ty])o 3/". areolata Hal.) 



Head transverse, broader than the thorax; ocelli 3, in a triangle, 

 the lateral ocelli about twice their width froni the margin of the eye; 

 eyes rounded. 



Antenn;e inserted just above the clypeus, 10-jointed in both sexes; 

 in the 9 not half the length of the body, ending in a 3-jointed club; 

 fnniclar joints very small, transverse; club joints large, broad, the last 

 conical, s<miewhat larger than the penultimate; m $ moniliform, incras- 

 sated toward apex and longer than half the length of body; first flag- 

 ellar joint minute; fourth, moderate, fifth, and following to the ninth, 

 larger and broader, tenth, conical, much longer than the penultinmte. 



Thorax short, ovate, finely scaly; jjronotum short, scarcely visible 

 from above; mesouotum with indistinct furrows; scutellum small, flat- 

 tened, semicircular; metathorax moderate. 



Front wings with the submarginal vein terminating in a stigma, the 

 basal uervure distinct, and with a basal cell. 



Abdomen ovate or oval, twice the length of the thorax, the apex 

 pointed, stylus-like in 9 ; first segment very short; second very large; 

 third, fourth and fifth short, about equal; fifth about as long as seg- 

 ments 3 4 and 5 united; sixth shorter; in S the abdomen is scarcely 

 longer than the thorax. 



Legs clavate. 



This genus and Monocrita Forster are the only genera in the family 

 having a distinct basal nervure, which alone is sufficient to distinguish 

 them from all others. The female in MetacUsis is separated from Mono- 

 crita by having a 3-jointed antennal club, the male by the smaller 

 second funiclar joint. 



But two species have been described.
