miul and ordure. Berania, at Ega so abundant, here was very rarely 

 seen, whilst Tutelina, which I never saw but once at Ega, is here 

 quite a common species. 



In the shady ravines of the forest many species of Ilhomia? were 

 found in greater or less abundance. After having observed last year 

 at Fonte Boa so much that was interesting and suggestive in the geo- 

 graphical distribution and mutual relations of the species, I was 

 curious to observe what further was to be learned at this new locality, 

 I found, as I had expected, an almost total change in the species. I 

 found here nineteen species of the genus, eight of which I had never 

 met with before : on the other hand, eight species found abundantly 

 at Fonte Boa, do not reach this place. I. lllinissa, ^lia and the 

 three allied species, forming a group having nearly the same colours, 

 would appear then to find their metropolis at Fonte Boa, and are 

 doubtless dispersed over the tract of level humid forests between the 

 Jutahi and Teffe, southward of the Amazon and stretching towards 

 Bolivia. The commonest species at St. Paulo was the I. Cidonia 

 [Hewits,) and another really near to it, but having a totally different 

 appearance on account of the partially white- coloured nervures ; this 

 latter as well as the other six species of St. Paulo Ithomia? are pro- 

 bably as yet undescribed. Ithomia Cidonia varies very much, but its 

 varieties all gradually blend together, and are by no means distinct 

 like the species allied to I. lllinissa. One species, however, of 

 similar colours to it is quite distinct, having differently coloured 

 shoulder-coverts and collar as well as peculiar neuration and antenaa?. 

 Flying amongst the Ithomiae was now and then to be observed a 

 Leptalis ; I was very careful to secure every specimen, and the 

 gathered series, now I come to examine them closely, have interested 

 me as much as any other acquisition made during my excursion. 

 Abstraction made of a white species and the Vocula, the rest may be 

 considered either as six species allied to L. Lysinoe {Hewits.), or as 

 the latter branching out into six rather widely differing varieties. In 

 either case they are very interesting, because some of the kinds come 

 to imitate, each a species of Ithomia common only in this locality. 

 It would seem then almost correct to say, that at Ega and other sta- 

 tions these new Leptales are not found, because the Ithomia? to which 

 they correspond are also absent. L. Lysinoe imitates Ithomia Flora; 

 but three at least of the new species imitate three of the commonest 

 Ithomiae of St. Paulo ; on the wing their resemblance is much more 

 striking than when in the cabinet. In fact I was quite unable to dis-
