of a small species of Pseudacreea of the boisduvali group which 

 I do not know. 



" I can now give you a little moi'e interesting information 



[xvi 

 about the blue spp, of Crenis and Crenidomimas concordia, 

 Hopff. The country I was in appears to be the metropolis 

 of the genus Crenis, and they swarmed everywhere. I 

 have taken occidentalium, Mab. (scarce), ? amtdia, Cr. (very 

 abundant), rosa, Hew. (abundant), pechueli, Dewitz (very 

 abundant), and at least 2 spp. of the 7iatalensis group, one 

 of which is remarkable for an under-surface exhibiting an 

 approach to the coloration and pattern of that of the blue 

 forms. I certainly begin to suspect that the blue species 

 of the genus, if not the others, are distasteful. They are 

 extraordinarily bold and fearless, and collect in very large 

 numbers wherever they can find moisture. They may often 

 be seen, almost in hundreds, round a damp garment in one's 

 camp. Their mimic Crenidovdmas concordia I found much 

 scarcer, but with very much the same habits. They are very 

 puzzling things, because it must be remembered that they are 

 also extremely addicted to fluttering round and settling on 

 tree trunks often some 10-20 ft. above the ground, and under 

 these circumstances they are very very incons2)icuous.
