New Geometridae (Lepidoptera) in tin- South African Museum. 69 



radials and moi-e markedly in posterior part, reaching hindmargin 

 little beyond the middle ; some weak dark shadings in distal area, in 

 part giving the impression of a less oblique continuation of the post- 

 median line from M 1 to hindmargin ; dark terminal line not very 

 sharp, slightly interrupted at the veins. Hindwing concolorous, at 

 costal margin paler and feebly marked ; median and postmediau lines 

 approximated, wavy or somewhat sinuous, the former only, the latter 

 chiefly, pronounced towards abdominal margin, here nearly parallel 

 with termen, anteriorly somewhat receding ; cell-mark scarcely indi- 

 cated ; some weak submarginal shades ; terminal line as on forewing. 

 Underside very feebly marked. 



Cape, Carnarvon, January, 1910 (J. Drury). 



The unique example is unfortunately in poor condition, but easily 

 recognisable by the structural characters combined with the facies, 

 which recalls some narrow-winged Algerian Hemerophila or Boarmia 

 atlanticaria Stgr., etc. 



GEN. PERIDELA Warr. 



30. PERIDELA PUNCTILINEA, sp. nov. 



cj. 30 mm. Face not tufted, whitish ochreous with dark speck- 

 ling. Palpus (broken in type) rather short, mostly pale, with some 

 dark speckling on sides and above. Crown somewhat ochreous. 

 Anteunal pectinations little longer than diameter of shaft. Thorax 

 and abdomen concolorous with wings. Hiiidtibia dilated, with hair- 

 pencil, abdominal spine developed. 



Forewing with fovea moderate; SC 1 - 2 coincident, free (type) or 

 touching C at a point (paratypes) ; whitish brown, tinged with 

 ochreous on the veins and about the lines ; irroratiou and strong 

 costal dots or strigulae dark fuscous ; lines dark fuscous, thickened at 

 costa ; antemedian oblique outward from two-sevenths costa, strongly 

 curved in cell, then very oblique inward and slightly sinuous ; median 

 slight, except at costa, nearly parallel with termen, very slightly 

 curving away at costa ; postmedian about 3 mm. from termeu, nearly 

 parallel therewith from hindmargin to E 1 , here bent, running vertically 

 to costa ; composed of rather large vein-dots, those on E 2 and SM 1 

 (fold) generally smaller ; cell-spot elongate ; some slight dark shading 

 proximal to the almost obsolete subterminal line; terminal dots 

 strong, somewhat elongate. Hindwing with termen somewhat irregu- 

 larly waved, slightly emarginate between the radials, very slightly 

 prominent at R 3 ; lines not thickened at costa ; antemedian wanting ;
