Ixvii 



sliglitly dentate, whilst anteriorly to this dentate portion is 

 a flat brush of modified scales. 



Internally and on the dorsal side of each clasper is a delicate 

 membrane swollen out into a kind of lobe. The saccus or 

 vinculum is slender and unusually long, as is also the oedeagus 

 shown in all the figures. 



The whole structure of these organs gives no clue to the 

 systematic position of the species. In my opinion the structure 

 of the male armature is rarely to be relied on as an indication 

 of more than specific affinity. Reference to the figures of the 

 male armatures of the Genus Acraea (Trans. Ent. Soc, 1912, 

 Plates VII to XV) will show that so great is the variety of 

 structure, it would be impossible to describe a typically 

 Acraeine form of genitalia. 



The Egg. — By softening bodies of female examples in 

 caustic potash, it was found possible to dissect out a few eggs 

 in various stages. None of these seemed to be quite mature. 

 The shape of the most advanced could be more or less restored 

 by mounting in fluid, whilst the external structure could most 

 easily be seen in dried examples, though these were, of course, 

 much shrivelled. 



Fig. 5 is a drawing made up from both moist and dried 

 examples and probably gives an approximate idea of the shape 

 and appearance of an almost mature egg. It has nine longi- 

 tudinal ribs ending in slight projections at the narrow or 

 upper end, whilst there are faint indications of horizontal 

 lines betv/een the longitudinal elevations. Though not 

 typically Pierine in form it at least resembles the eggs of that 

 family more than those of others so far as they are known 

 to me, and to that extent supports the view that P. paradoxa 

 is an aberrant Pierine species. 



New and Rare Lepidoptera. — Mr. G. Talbot exhibited 

 the following Lepidoptera on behalf of Mr. J. J. Joicey. 



Africa. — A new species of Charaxes from W. Kivu, col- 

 lected by T. A. Barns at 8500 feet; allied to lasti Smith. 



A new subspecies of Pieris brassicoides Lucas, collected hy 

 T. A. Barns, in the highlands of the Great Craters, Tan- 

 ganyika Territory, between 7500 and 8800 feet. The species 

 was hitherto known only from Abyssinia.
