NEW SOUTH AFRICAN GEOMETRIDAE. 
By Louis B. Prout, F.E.S. 
The following descriptions have been prepared almost exclusively from 
material in the collection of Mr. A. J. T. Janse, to whose zeal and success 
in collecting we owe so much of. our knowledge of the Geometridae of 
South Africa, and in particular of the Transvaal. Where not otherwise 
indicated, the types and cotypes are in his possession. 
One or two additions and corrections to my former paper (Ann., 
Transvaal Mus., HI, 194-225) will not be out of place here. 
SuBFAM. HeMITHEINAE.

Frons protuberant, with dense projecting hair. Palpus with first and 
second joints densely haired, third joint in $ long, smooth, slightly fusi- 
form. Tongue present. [Antennae lost.] Pectus and femora densely 
hairy ; hindtibia with four spurs ; tarsi spinose. Abdomen robust, not 
crested, not impossibly a little abraded. Basal area of wings hairy beneath. 
Frenulum fully developed. Forewing rather broad, with costa straight to 
beyond one-half, then gently curved, apex moderate, termen somewhat 
oblique, anteriorly straight, posteriorly gently curved ; cell rather short, 
DC inbent ; SC 1 free, SC 2 * 5 stalked, SC 2 arising considerably beyond SC 5 ; 
R 1 from apex of cell, R 2 from slightly before middle, M 1 separate from, 
though approximated, to R 3 . Hindwing with apex pronounced, termen 
strongly crenate, its general outline straight from apex to R 3 , then convex ; 
cell very short (only one- third), DC 3 curved, becoming very oblique ; 
C 1 well separated from cell near base and moderately rapidly diverging ;
