Dioptid moth Dioptis pellueida, all having a narrow hind-wing 

 margin of reddish brown, is a West Colombian development of 

 the better-known Bogota group with a much broader area of 

 hind-wing colouring extending nearly up to the costa and 

 covering the greater part of the wing. The Bogota species in 

 association are Leucoihyris amalda amalda, Pseudoscada lav mm 

 lavinia, Hypoleria vanilia vanilia and Pteronymia laura, the 

 last genus not being represented as far as is known in the 

 former group. Whether any of the species could be called 

 dominant in numbers it is difficult to say. None are common. 

 but some other species of the genus Pseudoscada are abundant, 

 and one might suspect in either case that the forms of this 

 genus w r ere commonest. 



Two other species of the Bogota or Eastern group form a 

 sub-group by themselves with a very heavy discal black band. 

 These two are Hypoleria aelia (Hew., " Ex. Butt.," i, nee 

 Hnsch. in " Seitz," p. 142) and Ithomia centromaculata (Wey., 

 Berl. Ent. Zeit., xliv, p. 300, fig. 2). Both of these two, of 

 which there has been such confusion as to their identity, are 

 rare species, and the exact locality of either (it will doubtless 

 be the same for both) is not known for certain. Hewitson's 

 locality for Hypoleria aelia is River Amazon, and he says in 

 the collection of Bates, but this is probably erroneous, and 

 if Bates had it, it is most likely that it came from a Colombian 

 locality. Of the Ithomiines surrounding the Dioptid moth 

 the Leucothyris (L. amalda amaldina) is the closest in pattern, 

 as it is the only species that has a black mark across the cell. 



Wasps' and Ants' Nests from Java. — Mr. Frisby ex- 

 hibited an ants' nest, sent to him by Mrs. M. E. Walsh, F.E.S., 

 from Soekaboemi, Java. 



She wrote : " This nest was found on the ground with all 

 the inhabitants dead. As everything was still fresh, an 

 accident must have happened — but what? " 



The nest, which is attached to the underside of a leaf, is of 

 soft papery material, about 3| inches long, with the opening 



white marginal spots clearer and whiter. Hind-wing with a brown 

 patch between outer margin and cell, but not reaching the cell.
