EAST AFRICAN MOTHS. 105 



with long black hairs ; patagia greyish. Abdomen black with five 

 orange rings, and an orange spot at its extremity. Wings white, 

 the veins fuscous. Fore wing : an antemedial fuscous fascia which 

 fills nearly the whole cell ; a black line on discocellulars ; post- 

 medial and submarginal fuscous fasciae ; a black marginal line ; 

 cilia fuscous. Hind wing white with only a submarginal fuscous 

 fascia, angled towards the margin at vein 3. 



Habitat. Kedai, 1st March and 25th November. Expanse 

 46 mm. 



This form is nearest to Sabalia sericea Weymer (only a figure 

 of which is in the British Museum), but differs as follows : — the 

 cell is fuscous ; the fuscous submarginal band is carried down to 

 vein 2 in the fore wing, whereas it stops on vein 4 in sericea. In 

 the hind wing the fuscous band is deeper, more sinuous, and 

 nearer the margin, and the veins are black throughout. 



84. Sabalia thalia, sp. n. (PI. I. fig. 17.) 



Description. — <$ . Head black; orange spots at base of the 

 antenna 1 , which are black and bipectinated. Collar broadly white 

 with a black spot doi\sally. Thorax covered with long black hair. 

 Abdomen black with five orange rings, and an orange spot at its 

 extremity. Fore wing pale brown, the veins white. A white 

 antemedial fascia defined outwardly with dark brown, bent in 

 basally on costa and inner margin. A brown spot on disco- 

 cellulars. A white submarginal line from apex to tornal angle, 

 defined inwardly by dark brown, beyond which the marginal area 

 is brown, crossed by the white veins. Hind wing ochreous at 

 base ; a dark spot on discocellulars, and a white submarginal band 

 as on the fore wing. 



Cilia of fore wing brown, of hind wing whitish. 



Habitat. Kedai, 26th & 27th November and 12th & 14th April. 

 Expanse 74 mm. 



This form is nearest to Sabalia picarina Walker, which has a 

 white hind wing and deep black marginal band. 



The specimens of the above two species which I have seen are 

 all males, and the species would appear to be at least double- 

 brooded. 



84 a. Anaphe panda Boisduval. 



Habitat. Kedai, 12th March. 



These specimens differ from panda from Natal in the fuscous 

 border of the inner margin being curved up basally towards the 

 thorax, and in having no distal band on hind wing, and in being 

 smaller. 



Sphingidje. 



85. POLIANA MARMORATA, Sp. n. (PI. II. fig. 22.) 



Description. — S • Head, thorax, and palpi fuscous above ; white 

 spots above the eyes. Palpi beneath white, as also pectus and
