74 A Monograph of Calicidae. 



has a broad apical white band, the third is nearly all white (a 

 minute black basal band), and the last two snowy-white entirely ; 

 ungues equal and simple. 



Wings mostly dark-scaled, four small creamy costal spots 

 (including the apical one), the first three spread evenly on to the- 

 first long vein, the fourth is longer on the first vein than on the 

 costa ; the third long vein has many pale scales, and there are 

 some on the branches of the fourth and upper branch of the fifth, 

 and a few pale scales on other veins, apices all pale, and there are 

 very distinct pale spots on the fringe at the junction of all of 

 them with it, rest of fringe very dark. First sub-marginal cell 

 longer and narrower than the second posterior cell, its base 

 nearer the base of the wing. 



Length. — 6 mm. 



Habitat. — Pretoria (Dr. Theiler). 



Observations. — Described from two J s. It is a most marked 

 species, easily told by the large golden thoracic scales and densely 

 scaled wings, which appear very dark.
