British Guiana Heteroptera. 



By J. R. DE LA TORRE BUENO, White Plains, N. Y. 

 Last year's collections of Heteroptera made by Mr. H. S.

 and the results are presented herewith. Only two papers on 

 this fauna are known to me, one, published by E. P. Van

 bearing the title, "Notes on South American Hemiptera Het- 

 eroptera," and dealing with Bartica material from Parish and 

 with other South American collections otherwise secured. The 

 former paper includes 89 species and the latter 67 species 

 from Bartica. The lot under consideration contains 86 species, 

 including all undetermined forms ; 67 have been determined 

 generically and specifically, 15 generically only, and four ob- 

 scure species remain unplaced except as to family. Of the 

 determined species and genera, 57 were not recorded by Van 

 Duzee and 50 by Osborn ; omitting older records, there are 

 among those we are considering 27 species (33 if we include
