18. Metathorax: with tiro transvei'se carin;e, the spiracles small, rounded, the pleu- 



ral carina wanting or vaguely defined posteriorly; median and sub- 

 median cells ecjual or sometimes with the median cell a little the 

 shorter; areolet with the sides convergent above; head quadrate or 

 sul )quadrate, the temples full, broad; antenna? filiform, ringed 

 with white, the first joint of tlie flagellum a little longer than the 



second ( 266 ) Kaltenbarhid Forster. 



Metatiiorax with only one complete transverse carina — the basal, the apical 

 transverse carina indicateil only laterally, or the upper hind angles 

 are toothed.

parallel; submedian and median cells equal; head transverse, the 



temples flat (268) Cryptoptery.c Ashmead, new genus.

19. Marginal cell rather short, the areolet large or moderate, the sides parallel <ir 



nearly, rarely small, with the sides convergent above; metathoracic 

 spiracles small, round, short-oval, oval or ovate, 7/«v'r elongate or 

 linear; abdomen most red, black at apex, and usually s])otted with

 in males), the pleural carina more or less distinct, the upper liind 

 angles sometimes dentate 20
