■examination. The species, as we understand it, is veiy close to 

 nebulosa, from which it seems best separated bj- the shorter and 

 broader fastigium, the less produced interantennal section of the 

 frontal costa, the slightly greater interspace between the eyes, 

 and the somewhat different shape of the ventral margin of the 

 lateral lobes of the pronotum. 



Of the series previously recorded l)y us,fromSapucay, Paraguay, 

 as signatipes,^^ four females should be referred to the present form 

 and the remainder to coerideipennis. The confusion of this 

 material was responsible for the comment there made on the 

 variability of the coloration of the ventro-external face of the 

 caudal femora. As we have shown elsewhere, however, almost 

 as great a degree of variation in this respect is found in coerulei- 

 yennis. The specimen from Misiones, later reported by us as 

 nebulosa,^'' was correctly associated, as an authentic pair loaned 

 by Prof. Bruner shows.

This specimen is inseparable from Paraguayan and Misiones, 

 Argentina material. We see no reason to separate Burmeister's 

 coelestre from this species, or to replace Thunberg's name by the 

 much later one. The distribution of this species appears to cover 

 the region from eastern Peru and Ecuador, south through Bolivia 

 and western Brazil to northern Argentina (Misiones, Jujuy, 

 Tucuman and Chaco), east to the vicinity of Rio de Janeiro, 

 Brazil. We have in addition records from Pard and Santarem, 

 Brazil and Trinidad, but we suspect these may refer to speci- 

 mens of flavo-lineata with a bluish green tint to the wing disks, 

 such as we have recorded elsewhere from northeastern Brazil.'^
