SPIONIADES.— EEACON. 365 



up into spots as in all the specimens before us. The large spot near the anal angle is 

 shown, and we have no doubt that our specimens may properly be referred to Spioniades 

 artemides. 



The range of this species extends chiefly over the eastern and northern portions of 

 South America ; we trace it to Venezuela, and even to the Isthmus of Panama, where 

 it comes into close contact with the allied S. abbreviate 



We figure a male from Chiriqui. 



The male genitalia have two long curved rods, one on either side of the central hook 

 •of the tegumen ; the harpes are symmetrical, cleft at the end into two thickened lobes 

 which slightly overlap each other, the lower one being truncate, the upper rounded.

This insect is very closely allied to Spioniades artemides, but may be recognized by 

 the slight characters given above. It was described by M. Mabille from a specimen in 

 Dr. Staudinger's collection kindly lent us by its owner, and now before us. With it 

 our series from Nicaragua southwards to Bolivia agrees very closely ; but a single male 

 specimen from the line of the Panama Railway belongs to the more eastern form, 

 S. artemides. 



ERACON, gen. nov. 



Arteurotia bitemata, Mabille, differs materially from the type of Arteurotia, and not 

 agreeing with any of the described genera we are obliged to assign it to a distinct 

 genus, though we do so with some diffidence, as our materials are not sufficient to 

 enable us to make a full examination of its characters by dissections. 



In shape of wings and in general coloration Eracon biternata resembles Pellicia 

 bromias (Mab.) (also placed in Arteurotia by that author), but the secondaries are 

 rather more elongated and the primaries more rounded at the apex ; moreover, there is 

 no tuft of hairs near the base of the costal margin of the secondaries. The primaries 

 have a conspicuous black spot with two white dots in the cell, recalling some members 

 of the genus Cycloscemia, in which, on the other hand, the secondaries are much less 

 produced. 



The antennae and palpi resemble those of Pellicia bromias, but the hind tibiae are 

 furnished with a tuft of L hairs as in Spioniades. There is no costal fold to the 

 primaries.
