produced, acute ; 3 absent, 6 and 8 stalked ; deep sliining bronze, 

 largely suffused with dark shining leaden-grey, but without defined 

 markings : cilia dark grey. Hihdwings and cilia dark fuscous ; 

 3 absent. 



Colombia, Call, 500 feet, and Caldas, 4400 feet, in May 

 (Parish); eight specimens. Vein 3 is absent in both 

 wings, as well as the other veins normally absent in the 

 genus, but the species is a true Heliodines. 



Lamprolophus obolarcha, Meyr.

 Ecuador, Huigra, 4500 feet; in May and June (Parish), 

 common. Varies remarkably in size, down to 7 mm. ; 

 basal half of forewing sometimes much suffused with 

 blackish. Emhola dentifera, Wals., Biol. Centr. Am., IV, 

 p. 4, pi. i, f. 6 (1909), from Mexico, is clearly a synonym ; 

 the genus Emhola does not seem properly distinguishable 

 from Lamprolophus.

 (Parish); fourteen specimens. This is a very singular
