Erechtia Walker, List Hom. B. M. Suppl. 141 (i858). 

 Tropidoscyta Stal, Hem. Fabr. II : 44 (1869). 



Characteps : Insects of small size with triangular bodies and with the pronotum usually angu- 

 late in front but without an anterior process. The sides of the pronotum are carinate, usually with three 

 parallel ridges, and the metopidium is strongly ridged above the eyes. The dorsal margin is straight 

 and slopes gradually from the top of the metopidium to the tip of the posterior process. The tegmina are 

 entirely free, almost entirely hyaline, and have five apical and three discoidal cells. All three pairs of 

 tibije are broadly foliaceous. In his original description of the genus, VValker calls attention to the 

 (( three parallel dorsal keels; the lateral pair abbreviated; the middle one continued to the acute tip » 

 but this condition is also occasionally found in the closely related genus Tyloptlta.
