Habitat. — There are specimens at hand from Chapada, Para, 

 Rio de Janeiro, etc., as well as from Montevideo. They were col- 

 lected from March to November (H. II. Smith). 



There are great variations in robustness, length of wing, coloration, 

 etc., in the measurements of specimens before me as I write, possibly 

 sufficient to warrant the making of at least two, if not three species. 

 The generic affinities of these insects are certainly closer to Munatia 

 than to Procolpia as suggested by both Rehn and Giglio-Tos.

The genus Diedronotus Bolivar {Tropinotus Serville) is confined 

 to tropical America, where it is represented by a rather large number 

 of attractive species. While enjoying a range extending from 

 Yucatan in the north to the Rio Negro in the Argentine Republic, 

 its center of distribution seems to be in southern Brazil and Paraguay. 

 At least fifteen species have been heretofore described. To these
