 folding. 



Though very close, we l)elieve that Melestora and Cotwpsodes 

 represent distinct generic units, occupying the same position in 

 the biota of the regions where they are found, the former in the 

 southern portion of tropical South America, the latter in tropical 

 North America.

This species was apparently introduced into Brazil, probably 

 from Oceania, a very long time ago; it was recorded from Brazil 

 at an early date and definitely from Rio de Janeiro by Gerstaecker 

 jn Van der Decken.^^

The present material is assignable without question to Walker's 

 cynipsoides, which name has been placed in synonymy under H. 

 fieberi (Brunner) by Kirby. We do not believe Kirby 's action to 

 be correct, but examination of the type of fieberi alone can verify 

 this. It would seem probable that Brunner would have described 

 the large and strikingly pale spot of warm buff, on each side of 

 the abdomen latero-proximad, had his material shown this feature. 

 This marking is, as described by Walker, conspicuous, occupying the 

 lateral portions of the first and second tergites and corresponding 

 area ventrad, and shows through the fenestrate tegmina when these 

 are at rest.
