On a new Genus and Species of African Moths. 295 



XXXIII. — Description of a new Genus and Species of 

 African Moths. By A. G. Butler, F.L.S., F.Z.S. &c. 



The following very remarkable new genus is so aberrant 

 tliat, although there can be little doubt that it is distantly 

 related to Hypena, no nearly allied form has been recorded ; 

 in the form of its wings it somewhat resembles the males of 

 the Erosiid genus Dirades^ with which, iiowever, its structure 

 in no respect corresponds. 



I propose to name this wonderful novelty, in honour of its 

 zealous and learned owner, 



HOLLANDIA, gen. nov. 



Primaries very broad, the costal margin arched at base, 

 very nearly straight (if anything slightly concave) to near 

 apex, where it is again convex, and passes almost imper- 

 ceptibly into the outer margin ; the latter very convex, but 

 forming a nearly straight oblique line from third median 

 branch to external angle, which is rather acute ; inner margin 

 slightly convex. Costal vein extending nearly to apex ; 

 subcostal five-branched, the first branch emitted before the 

 end of the cell, the three following near together at some 

 distance beyond it, the second and third being slightly curved 

 upwards at costal margin, the fifth emitted, with the upper 

 radial, from anterior angle of cell ; lower radial emitted close 

 to the second and third median branches from the posterior 

 angle of the cell. Secondaries comparatively small, with the 

 costal margin widely arched and forming its apex at end of 

 third median branch ; the costal and subcostal veins, which 

 anastomose at base, consequently curving upwards to costal 

 margin ; outer margin nearly straight ; abdominal margin 

 obtusely elbowed ; a large sericeous pyriform sexual patch on 

 upper surface crossed by the radial and second and third 

 median branches ; discoidal cell very short, with the disco- 

 celular veinlet transverse and very slightly concave ; the 



toward the anal angle. A broad patch of raised scales upon the middle 



of the posterior wing above, and the costa of the posterior wing with the 

 scales closely appressed, presenting a shining silky surface. Upon the 

 underside of the primaries a siniihu' arrangement of the scales is found at 

 the base and the basal end of the inner margin, and in the midst of this 

 shining area there is a large patch of raised scales partly covering the 

 cell. 



Type T. subolivescens.
