Cliambezi Valley, Karunga River, 4500 feet, Jan. 1917 

 (S. .1. Barns) s type in coll. Joicey. Also a short series from 

 150-200 miles W. of Kambove; 3500-4500 feet; 9 th-1 lth 

 Oct. 11)07 (S. A. Neave), in coll. Brit. Mus. 



Neither of the descriptions of Karsch's species (tippels- 

 leirehi^ Karsch, Ent. Nachr. xxiv. p. 293; fHlleborni t id. ibid. 

 xxvi. ]>. 354) can refer to this species ; in the latter the fore 

 wing is wholly black in the cell, etc. ; the former may 

 probably be nearer, but — apart from its considerably larger 

 size — lacks the pale patagia. The structure of the fore legs 

 will need closer attention than I have been able to give; in 

 the type-specimen of barnsi they are lost. 



Family Geometridae. 



Subfamily TIemitheinm. 



2. Comibcena hypolampes, sp. n. 



<$ . — 30 mm. 



Head white, the crown somewhat mixed with green, the 

 palpus on the sides with brownish. Antennal pectinations 

 not quite so long as in chalybeata, Moore. (Body discoloured 

 in relaxing.) 



Fore icing with SC 1 free, SC 2 arising considerably before 

 SC 5 ; bright green, finely strigulated and irrorated with 

 white; costal edge narrowly white ; two broad white trans- 

 verse lines, the first straight, at about 5 mm. from base ; the 

 second slightly curved near costa (3 mm. from apex), then 

 nearly straight to hind margin near tornus ; some slight 

 white clouding in distal area; no terminal line; fringe white. 



Hind icing with frenulum slender; termen nearly rounded, 

 a little straighter between the radials ; SC 2 very shortly 

 stalked, M 1 nearly connate ; costal area white, the rest con- 

 colorous with fore wing; otherwise unmarked except by a 

 very fine white line close to termen as in Euchloris smarag- 

 daria or chlorophyllaria. 



Fore wing beneath bright green, posteriorly nearly white, 

 and with some white admixture in distal area; first line 

 slight, second strongly developed ; hind wing beneath green, 

 with white irroration and strigulation, postmedian line of fore 

 wing continued, bluntly bent at B 3 .
