FiGUBES 50-54, 108-109 



Coelidiana subgenus Coelana DeLong 1953, p. 128. Type of subgenus Neocoelidia 

 modesta Baker by original designation. 



Description. — With carina separating face and crown. Crown in 

 dorsal view broadly angular at apex and slightly wider than long. 

 Ocelli on anterior margin of crown. Head including eyes distinctly 

 narrower than pronotum. Posterior margin of pronotum broadly and 

 sharply indented. Antennae about half as long as body including 

 forewings. Venation of forewings obscure except apically. 



Ground color stramineous with small black spot at coronal apex. 

 Forewings stramineous hyaline. 



Male genitalia: Valve lacking. Male plates fused basally. Py- 

 gofer greatly inflated, clearly exceeding length of plates, and ventral 

 margin with large and heavy hook. Anal tube with ventral process. 

 Connective approximately Y-shaped and articulated with simple 

 aedeagus. 



Discussion. — Ooelana includes two species, G. modesta (Baker) 

 (figs. 50-54) and C. drakei new species, from South America. Both 

 are known from Bolivia, but G. modesta is recorded also from northern 

 Argentina and southern Brazil.
