New Geometridae (Lepidoptera) in the South African Museum. 53 



The coloration and dotted markings recall some Palaearctic Laren- 

 tiids, notably Calostigia mitUistriyaria Haw. or sharply-marked Eiiphyia 

 intfrsecta Stgr. 



GTEN. LARENTIA Tr. 



8. LARENTIA DIPLOCAMPA, sp. nov. 



. 31mm. Face without projecting cone; fuscous with some pale 

 admixture. Palpus shortish ; as face, the first joint entirely pale 

 beneath. Vertex, thorax and abdomen concolorous with wings. 



Forewing with termen only very faintly waved ; DC biangulate, 

 though not as strongly as in hind wing, R 1 stalked, R 2 from slightly 

 behind middle of DC ; wood-brown, shaded with cinnamon and with 

 irregular, coarse, fuscous irroration ; costal edge somewhat dotted with 

 fuscous ; lines dark fuscous, rather fine, not well defined ; autemedian 

 at somewhat beyond one-third, apparently angled outward at cell- 

 fold, then sharply oblique inward, vertical and somewhat thickened 

 across M, again oblique inward for a short distance behind, then nearly 

 vertical (a little sinuous) to hind margin ; somewhat thickened on 

 crossing SM 2 ; sinuous lines and irroration proximally to this line 

 prevent its being well differentiated ; a fairly distinct line in median 

 area, about 1'5 mm. from the antemediau, approximately parallel with 

 it in anterior part, curved outward at submedian fold ; succeeded 

 distally by a narrow pale median space ; postmedian line at rather 

 beyond two-thirds, markedly lunulate-dentate, bilobed between R 3 and 

 M*, slightly iiibent at R 2 , inbent at M 2 ; 2 or 3 feebler lines in median 

 area proximally to this, nearly parallel with it but less bilobed ; pale 

 band beyond postmedian not conspicuous ; proximal boundary-line of 

 terminal area almost parallel with postmedian : some weaker crenulate 

 lines between this and ternien ; a short oblique mark at termen close 

 to apex ; terminal dark line somewhat interrupted at veins and folds 

 (fringe wanting). Hituhving prominent at end of SC 2 ; termen waved ; 

 paler than forewing : a dark discal dot, rather weak postmedian line 

 (excurved about R 2 -M 2 , slightly incurved posteriorly) and still weaker 

 traces of one or two other lines. Forewing beneath greyish, proximal 

 part unmarked, postmediau lines present, feeble posteriorly ; a slight 

 brownish subterminal band in anterior half, pale-edged distally, 

 especially between SC 5 and R 1 . Hiudwiug beneath more strongly 

 marked than above. 



Cape, Cape Town, April, 1913 (P. C. Keytel). 



Size, shape and colouring (though this is rather less bright) recall 

 Ortholitha ferridotata Walk., but the discocellulars are different, the 

 lines differently formed, white lines wanting, underside less brown.
