 Callosphingia gen. nov. 



? . Palporurn articulns secundus intus profunde concavus et sqnamis longis 

 dense tectus ; tarsorum anticorum articnli spinis longis armati, scilicet primus 

 qnatuor, secundus et tertius una apicali. — Genotypus : Dovania circe Fawcett (1915). 



The second segment of the labial palpus is concave on the inner surface as in 

 Herse, Ackerontia, and Coelonia. In this groove there are a number of erect hair- 

 scales in the centre, and the scales placed at the proximal and lateral edges of the 

 groove lean towards the centre, forming a dense roof over the cavity, the roof being 

 absent distally, where the cavity is open. First segment with a naked streak 

 on the inside ; third segment short, almost concealed in the scaling of the second 

 segment. Head rather small. Pilifer normal, bearing bristles only ; genal process 

 short, obtuse ; tongue long (rolled in, not measured). Antenna distinctly incrassate 

 distally, end-segment long, with rough scaling, preceding segments higher than 

 long. Tibiae without spines, spurs of mid- and hindtibiae very unequal, the long 

 inner spurs about twice as long as the outer ones and not quite reaching to the 

 middle of the first tarsal segment. First segment f foretarsus much shorter than 

 foretibia, on the outer side with four stout long spines and some small ones ; 

 segments 2 and 3 with a long apical spine ; pulvillus present, long, paronychia with 

 one slender lobe ; midtarsus with basal comb, the distal bristles of which gradually 

 diminish in length ; hindtarsus without comb ; first hindtarsal segment nearly as 

 long as the other four segments together. 



To be placed after Coelonia. 



1. Foliana natalensis ferax subsp. nov. 



c? ? . Maculis et fasciis nigris magis abundantibus et melius expressis quam 

 in P. n. natalensi. 



Hab. German East Africa : Manow ; a series received from Messrs. Staudinger 

 and Bang-Haas. 



The black lateral stripe of the thorax is broader than in southern specimens, 

 the tip of the patagia being edged with black and the yellow spots of the 

 metanotum usually more or less distinctly surrounded by black ; the thorax and 

 abdomen, above, darker than in P. n. natalensis, especially in the ? , the abdominal 

 spots deeper black, the lateral ones, moreover, being somewhat larger. Scaling of 

 antennae and tarsi slaty-grey in most specimens, darker than in P. n. natalensis. 



Forewiug, on upperside, with an abundant intermixture of black scales in most 

 examples, the wing being particularly dark in the ¥ ? ; the transverse lines more or 

 less complete, but one of the c? c? approaching P. n. natalensis very closely ; the 

 fourth line from the base joins the discocellular ring in P. n. natalensis, while in 

 P. n. ferax it remains separate from the ring or is only joined to it at the lower 

 cell-angle (in the type-specimen of ferax) ; the greyish white marginal patch at
