terminal joint in ^ abbreviated. Antennae in (J ciliated, in 9 

 simple. Thorax not crested, slightly hairy beneath. Abdomen 

 sometimes with metallic dorsal crests; in ^ with lateral tufts on 

 terminal segments. Posterior tibia? in ^ dilated; all spurs 

 present. Himlwings witli termen straight and long, forming a 

 rounded projection at tornus containing a dark spot; a strong 

 rounded costal expansion at Ijase; frenulum in ^ present but 

 rather slender, in 9 obsolete. Forewings with .3 and i short- 

 stalked or connate, 6 short-stalked or connate, 11 free or rarely 

 anastomosing with 12. Hindwings with 3 and 4 stalked, 6 and 

 7 stalked, 8 touching cell at a point near l>ase, then rapidly 

 diverging; discocellulars nearly straight, moderately oblique. 



Type lodis hipunctifera Wlk. Closely allied to MetaUocJdora 

 Warr., differing only in the peculiar form of the hindwings, which 

 in this instance appears to be sutlicient, also I)y the lateral 

 abdominal tufts of ^. The occasional presence of metallic 

 crests on the ab(]omen is an interesting indication of atfinity. 

 They are usually completely absent.
