side of the lattei* butterfly, so unlike that of the ordinary 

 Pierine, is mimetic in character. But if we attempt to assign 

 it a place in the telesiphe combination, we are met by the fact 

 that whereas C. and //. telesiphe inhabit Ecuador, Peru and 

 Bolivia, P. antodyca is only known from Southern Brazil. 

 It may of course be the case that the range of one or more of 

 these species is wider than we are at present aware of ; it is 

 also conceivable that they may be linked together geographi- 

 cally by forms as yet unknown to science. But in the absence 

 of any definite information on these points, we must be content 

 to leave it as a puzzle that while the Pereute bears only a rough 

 resemblance to Heliconine forms such as II. besekei, Monetr., 

 and H. erato phyllis, Fabr., which inhabit the same part of 

 the South American continent with itself, it is strikingly 

 similar in aspect to a Heliconius which is separated from it in 

 geographical position. 



" A final matter of interest is the appearance on the 

 under side of the hind-wing of H. telesiphe of dark nervular 

 and internervular streaks radiating from the base of the wing 

 towards its periphery. This is an aposeme of very wide- 

 spread occmTcnce among Neotropical butterflies, being found 

 in Nymphalines, Heliconines, Acraeines and Erycinids, besides 

 other groups. In Pereute antodyca it is present, though not 

 to a vei'y marked extent ; in many other Pierines it is present 

 and strongly mimetic. It is well seen in Heliconius hortense, 

 Guer., hei'e exhibited, but is absent from the cryptic under 

 surface of Colaenis telesijihe."
