 insects had been placed in the hands of different persons for 

 examination, and the following reports were now presented 

 to the Section. 



Notices of the Hemiptera obtained by the Expedition 

 OF PpvOf. James Orton in Ecuador and Brazil. By P. 

 R. Uhler. 



The following list of species gives but a faint idea of the Hcmip- 

 terous Fauna of the sections of country traversed by this expedition. 

 No large collection of Hemiptera from those interesting regions exists 

 in the United States. Accordingly one cannot fail to lament the 

 absence of at least a moderate aggregation of the more common types 

 there so abundant. The great basin of the Amazons, as well as the 

 sti'eams forming some of the sources of this river, along which the 

 expedition proceeded, is represented in Europe by some thousands of 

 species. In this collection, however, we have no forms from the 

 extensive group of Scutelleroids, only three Pentatomoids, four Cor- 

 eoids, one Lygaeoid, one Pyrrhocoroid, and a fragment of a Redu- 

 vioid. Those constitute the only representatives of the Heteroptera, 

 while the common Fulgora, an imperfect Cicada and two Tettigo- 

 noids are the only Homoptera which were brought home by the 

 expedition. 



That a fine opportunity to supply some one of our collections with 

 a considerable series of the most important anel instructive tonus of 

 this highly interesting order of insects has been omitted, those will 

 best appreciate who have attempted in the United States to make 

 investigations in this field.
