The family thus bore a considerable resemblance to the 

 much larger one bred by Mr. Leigh in 1910 from a trophonius 

 female captured at Pinetown, Natal (Proc. Ent. Soc. 1911, pp. 

 xxxiii-xlii). The fact that the leighi form had now appeared 

 in a second family with trophonius parentage was of much 

 interest. 



Mr. Leigli also wrote in the same letter : — 



"I have quite recently seen a male dar Janus courting a 

 female Danaida chrysippus in error, and so persistently 

 indeed that I captured the specimens thinking I must have 

 made a mistake and that the female was really the trophonius 

 form." 



Further families of Pseudacraeas of the hobleyi group 

 bred by Dr. G. D. H. Carpenter on Bugalla in the Sesse 

 Archipelago. — Prof. Poulton exhibited the two families and 

 the leaves of the food-plant referred to in the following ex- 

 tracts from letters received from Dr. Carpenter. The history 

 of the families he hoped might appear as part of an Appendix to 

 Dr. Carpenter's paper in the Transactions. The numbers and 

 letters referred to the figures of Dr. Jordan's plates. 



"Oct. 14, 1912. 

 " I received Dr. Jordan's paper by the same mail as your 

 letter and was amazed to see how the Western eurytus forms 

 varied. I had not the least idea of it. Some of the forms I 

 have seen here, and sent you, viz. one like 21a (which I take 

 to show how rogersi arose), and a form like 14a or 15a, which 

 I mentioned in my last letter. I did not know, also, that the 

 form like hobleyi (24a) occurred in West Africa. It seems a 

 strange thing that imitator does not vary. I should expect, 

 if it did, to see the following slight variations in a long series. 



"I. A trace of yellow in the subapical white area, which is 

 that of terra, as shown very well by my beautiful bred 



[cxxxvii 

 specimen B 2 , which, as I remarked before, showed very 

 well how imitator could have arisen from a mixture of 

 terra, hobleyi, and obscura, 



''II. A trace of yellow suffusion on f.-w. inner margin (due 

 to terra).
