coalesces, forming a whole band; a narrow uninterrupted yellow 

 band, reaching from the fore border to a very short distance of the 

 hind one, a juxta-apical yellow macule ; nearly below the median 

 yellow patch and situate close to the hind border is a transverse 

 macule and between the apical patch of the second band and the 

 third one a minute yellow dot. 



Length of body 40 mm. ; width : fore wings expanded 92 mm., 

 hind wings 85 mm.

Padpakes dubiosus, n. sp. 



This species is so closely allied to the well-known P. speciosus, L., 

 that I hesitated to separate it as long as I had only female examples, 

 but now that I have seen two male examples I have no longer any 

 doubt that the two are different. A characteristic of P. dubiosus is 

 the constant, smaller size. The colouring of the wings and body is 

 the same, but the hind wings are more flavescent, and they have not 

 along the posterior border of the hind wings the conspicuous black 

 tessellation of P. speciosus ; in the ^ the clasps are much longer 

 and more slender than in P. speciosus, being almost in the shape of 

 a tuning-fork. 



In the six examples that I have seen the sub-basal black median 

 patch of the hind wings stands by itself as in the great majority of 

 examples of P. caffer, Burm., from which, however, this species 

 diflers more than from P. speciosus. 



It seems to replace the latter in the north-western part of the 

 Cape Colony, although assimilating somewhat to examples from 

 Namaqualand. 



It is recorded from Touw's Eiver (D. P. Lefebre), Clanwilliam 

 (L. Leipold) ; Bushmanland (G. Alston), Kimberley (M. Wilman). 



Length of body 38-59, of fore wings expanded 72-87 mm., of 

 hind wings 70-80 mm. 



PALPAEIDIUS, n. gen. 



Eesembles Palpares, but separated from it by the absence on the 

 posterior wings of the triangle-shaped furcation of the posterior 

 cubitus, the recurrens or retrograding vein of Kolbe, and thus 

 resembling the neuration of Creagris, and also by the very singular 

 shape of the clasping organs of the male, the superior part of the 

 appendages of which is produced into two very long cylindrical 

 processes densely hairy especially in the inner part.
