6 Mr. A. J. T. Janse on new South African 



as brown lines irrorated with fuscous. In perfect speci- 

 mens is a line of silvery scales at submedial fold and similar 

 scales just beyond the subterminal Hne; hind- wing smoky 

 grey. I have many males and two females. My twelve 

 typical argenfis'parsalis specimens all come from S. 

 Khodesia (Salisbury, Emangeui and Umtali in December 

 and January), except one which is from New Hanover 

 (Natal) in February. From the latter locality I have a 

 specimen of var. fuscata and one of var. pallidifascia, but 

 all my other specimens of these varieties come from Kar- 

 kloof (not far from New Hanover) and were caught in 

 January. 



pallidifascia, var. nov. 



This variety is in colour of fore-wing like fuscata, but 

 has a long fascia of ground-colour in middle of wing from 

 near base to subterminal line and just under the black 

 point. This fascia is more or less diffused, and when 

 many specimens are available this form wnll merge into 

 the fuscata form. I have many males and two females 

 of this form, all coming from Natal, all but one from 

 Karkloof, one from New Hanover. 



At first I thought fiiscafa to be distinct from argenti- 

 sparsalis, but by carefully comparing a large amount of 

 material I came to the conclusion that these two forms 

 are only varieties. It is peculiar, that I have not yet had 

 the typical form from Natal, but only from Rhodesia. 



Mesolia uniformella, sp. n. 



Female. Ground-colour of head, thorax, abdomen and fore- wing 

 cream- colour ; head and thorax irrorated with cinnamon-buflE 

 (xxix) ; maxillary and labial palpi irrorated with cinnamon- buff, 

 leaving the base of the labial palpi white; abdomen irrorated and 

 tinged with cinnamon- buff, on the underside of ground-colour; legs 

 white, femur and tibia of fore-legs densely irrorated in front with 

 saccardo's umber (xxix) ; mid-legs only slightly irrorated with that 

 colour; tarsi of fore- and mid-legs irrorated with saccardo's umber 

 in middle, especially the fore-legs, so as to leave a ring of ground- 

 colour above and below it; tarsi of hind-legs only very slightly 

 irrorated in that way. Fore-wing mth the whole of the basal, 

 costal and apical area and the postmedial line densely irrorated with 

 cinnamon- buff ; medial area from cell to inner margin thinly irrorated
