Three specimens have the posterior tibiae blackish. Tliis character 

 is not mentioned in the original description; the fourth specimen 

 has the tibiae of the same color as the elytra, and this color is variable 

 from reddish yellow to ferruginous. The pectinate white scales are 

 not so scattered. The author thinks such characters do not differ 

 sufficiently to warrant a varietal description. 



Length 1.65-1.73 mm. (type 1.5 mm.) ; width 1.13 mm.
