PROTOTHEORA PETROSEMA, Meyr. 



(J 9 . 22-23 mm. Head, palpi, and thorax fuscous, tiuely speckled 

 with white, apex of thoracic crest dark fuscous. Abdomen grey, 

 segmental margins whitish. Forewiugs light brownish-ochreous, with 

 a pattern of fuscous irrorated with whitish specks, viz. an irregular 

 basal patch, narrow irregular fasciae before and beyond middle, and 

 a subterminal fascia broadly dilated upwards, these narrowly con- 

 nected in middle, in 9 traversed by a white .streak which runs from 

 base of costa through middle of disc to near termen and thence to 

 apex, partially edged with blackish scales ; distinct blackish marks on 

 upper edge of this between fasciae in both sexes ; fuscous spots 

 speckled with whitish on costa between these fasciae, sometimes 

 suffusedly confluent with them : cilia fuscous, tinged with whitish, 

 on termeu base sometimes obscurely barred with whitish and fuscous. 

 Hindwings grey ; in $ an erect subdorsal brush-like tuft of long 

 Avhitish hairs near base ; cilia pale grey. Genitalia of <$ ; uncus 

 forming two moderate slender curved converging spine-like processes ; 

 gnathos forming two long down-curved diverging stronger spine-like 

 processes ; valvae long, slender, slightly expanded near apex, tolerably 

 pointed, clothed with rather long hairs. 



CAPE COLONY, Capetown, in April and May (Lightfoot) ; three 

 specimens (2 ^, 1 9). The tuft on hindwings in 9 is a quite ex- 

 ceptional structure ; it appears to be natural, but needs confirmation 

 in a second specimen.

 with white (thorax mostly defaced). Abdomen grey, segmental 

 margins whitish. Forewiugs light brownish-ochreous ; an irregular 

 white median stripe from base to beyond cell, thence much thickened 

 irregularly and running to costa near apex, edged with some scattered 

 blackish scales, upper edge more strongly blackish-margined before 

 and beyond middle; costal area above this anteriorly suffused with 

 fuscous, posteriorly with three fuscous fasciate spots speckled with 

 whitish, connected with median streak ; a dark fuscous terminal line : 

 cilia pale grey, towards base whitish. Hindwings light grey; cilia

 processes, sharply serrate on outer edge ; valvae short, broad, apex 

 bilobed.
