 wholly or predominantly ferruginous. 



Length 18-20 mm. Described from three males and five females. 

 The males, including the type, and one of the females bear the simple

Genotype. — Monedid^ magni-flca Perty. 



This genus is very closely allied to the genus Sticfia, from which 

 it differs, however, in having the ocelli provided with well-formed 

 lenses, in having the middle of the vertex not depressed but on a 

 level with the top of the eye, in having the inner margins of the 

 eyes strongly divergent at the clypeus, in having the temples broad, 

 and in having the nervulus vein distinctly postf ureal. 



Head narrower than thorax; eyes naked; ocelli provided with 

 lenses; anterior ocellus circular in form but scarcely more than a 

 semicircle in extent ; inner eye margins strongly divergent at clypeus ; 

 vertex not depressed, middle part on a level with the top of the eyes ; 

 frons below anterior ocellus and dorsal part of clypeus distinctly 

 carinate on median line; clypeus on either side the median carina 

 somewhat depressed, ventral area more or less flattened; maxillary 

 palpus composed of six segments, labial of four; nervulus joins the 

 discoideus distinctly distad of the origin of the basal vein; middle 

 coxa of male with short tooth; prominent groove and stout tooth 

 on posterior, apical border of middle femur of male ; seventh tergite 

 of male with short, stout, lateral spines, and with median part short, 

 broad, and truncate; eighth sternite of male ends in a single stout, 

 curved spine; second and sixth sternites of male may or may not 

 show distinct modifications or processes.
