New Geometridae (Lepidoptera) in the South African Museum. 61 



Forewing slightly less pale, only differing essentially in that the 

 oblique black line and its accompanying shades are markedly waved 

 or crenulate throughout instead of straight ; in addition, some 

 extremely fine black lines, faintly discernible in apicata, are more 

 noticeable, one curving backward and inward from the cell-dot, another 

 running out from this to a very acute angle on R 1 , touching the anterior 

 brown shade, then running obliquely inward and sinuous, parallel 

 with the stronger black line and again touching the anterior brown 

 shade on M 1 and on M 2 ; the curved white line distally and posteriorly 

 to the oblique line and shades (often fairly conspicuous in apicata, 

 though not noticed in Warren's description) is purer and rather 

 broader, hence very conspicuous. Hindwing also less pale and with 

 the faint lines sinuous. 



Orange Free State, Smithfield (Kaunemeyer), type in coll. S. Afr. 

 Mus. ; Maseru, Basutolaud, April llth, 1902 (R. Crawshay), a larger 

 (37 mm.), duller 9 in coll. Brit. Mus. ; a worn <$ without locality, 

 nearer to the latter in size and apparently in coloration, in coll. L. B. 

 Prout. 



The 9 antenna is shortly bipectinate. 



20. HEBDOMOPHRUDA EBEANS, sp. nov. 



c?. 24-29 mm. Also near to apicata and especially (in the crenulate 

 postmedian line) to crenilinea. Antenna of <$ with the pectinations 

 somewhat shorter (scai'cely over twice diameter of shaft, against 

 thrice in apicata) and stouter. Abdominal dark shading more 

 posteriorly placed. 



Forewing with termen more waved, cell slightly longer still, M 1 

 arising close to R 3 (in crenilinea rather widely separate) ; autemedian 

 line expressed, in places thickened (especially at costa), oblique out- 

 ward from one-fourth costa or rather beyond, biangulate in cell and on 

 M (W-shaped), then very oblique inward to one-fifth hindmargin ; 

 cell-mark vague, elongate ; postmedian line rather more proximally 

 placed, crossing M 1 near the cell (in crenilinea midway between cell 

 and termeii), throwing out small dashes proximally on the veins ; the 

 dark shades proximally to this line fairly strong, at least in posterior 

 part of wing, but ill-defined, no dark line or shade distally ; an oblique 

 dark cloud on hindmargiu midway between postmedian line and 

 tornus or rather nearer the latter. Hindwing with termen rather 

 strongly and irregularly creuulate, a rather conspicuous tooth at end 

 of R 3 ; postmedian line sharply defined from abdominal margin about 

 to R 3 , scarcely crenulate, obsolete anteriorly ; at abdominal margin
