some neio Lejndoptera-Heterocera . 391 



black lines are whitish or pale buff, the brown area occupied by the 

 succeeding eight black lines is broader ; the subnaarginal ocelloid 

 spots are more uniform both in size and colour, those towards the 

 anal angle not being relieved by white as in B. swanzii; the 

 external border is decidedly darker ; the thorax is uniformly 

 blackish piceous ; the antennae and connecting band cream- 

 coloured ; the abdomen is tawny, with slightly paler margins to 

 the segments; the dorsal white line is absent; on the under 

 surface both wings and body are much darker than in B. swanzii ; 

 the central white band on the wings is very narrow, as on the 

 upper surface ; the legs are much paler. Expanse of wings, 

 122 mm. 



About 50 miles inland from Mombaza. 



SATUENIID^. 

 Saturnia ivallengrenii, Felder. 

 ^ . Differs from the female chiefly in the much more acutely 

 zigzag outer edge of the central belt of primaries, and the smaller 

 and less prominent marginal white spots on all the wings. Ex- 

 panse of wings, 89 mm. 



About 50 miles inland from Mombaza. 



I cannot think that the above distinctions have more 

 than a sexual value ; at any rate, it would not be safe to 

 separate the Mombaza insect specifically without seeing 

 the female. 



Ccrancliia mollis, n. s. (PI. XTI., fig, 5). 



5 . Primaries soft greyish brown ; the basal, costal, and post- 

 median areas suffiised with ash-grey ; a transverse oblique snow- 

 white band just before the middle from subcostal vein to inner 

 margin, its inner edge sharply defined and slightly wavy, its outer 

 margin diffused ; an oval transverse ocellus, black edged with 

 whitish, and encircled by a rose-coloured line immediately beyond 

 the cell ; secondaries with a similar ocellus, but encircled with 

 brownish instead of rose-colour ; external two-fifths ash-grey, 

 shading into brown towards outer margin ; body white, antennas 

 black ; wings below greyish brown, with white internal areas ; the 

 ocelli of the upper surface represented by white-bordered black 

 spots ; palpi and pectiis brown ; venter white. Expanse of wings, 

 94 mm. 



About 50 miles inland from Mombaza. 



The pectinations of the antennte are less regular in 

 length in this species than in the other described forms 

 of Cerancliia.
