(Ty\t(i M. areolata Hal.) 



Head transverse, broa<ler than the thorax; ocelli 3, in a triangle, 

 the Literal ocelli alxmt twi<*e their width from the margin of the eye; 

 eyes rounded. 



Antenna; inserted just above the clypeus, lO-jointed in both sexes; 

 in the $ not half the length of the body, ending in a o-jointed club; 

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

 conical, somewhat larger than the i>enultimate; in S moniliform, incras- 

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

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

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



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

 from above; mesonotum with imlistinct furrows; s<mtellum small, t' »t- 

 tened, semicircular; metathorax moderate. 



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

 basal nervure distinct, and with a basal cell. 



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

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

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

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

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

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

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

 second funidar joint. 



But two species have been described.
