Genus ScARiA Bolivar. 



Scaria Bolivar, Ann. Soc. Ent. Belg., XXXI, 1887,301. — Hancock, Genera I n- 

 sectorum, fasc. 48, 1906, 69. 



The genus Scaria appears to be confined to the extreme southern parts 

 of North America and to the South American continent, where it is repre- 

 sented by at least four distinct species. These may be separated by the 

 following synoptic table: 



A. Apex of elytra flavo-maculate. 



b. Sides striated with black hamata De Geer. 



bb. Sides not striated with black prodiicla Hancock. 



AA. Tegmina not flavo-maculate. 



b. Dorsum of pronotum furnished with a pallid median line; length of body, cf 



9, 8-10 mm lineata Bolivar. 



bb. Dorsum of pronotum at middle ornamented with an oblong ferruginous 

 macula; length of body, cf 9 . 9-1 i-S mm rnaculata Giglio-Tos.
