British Guiana Heteroptera. 
By J. R. p— ra Torre Bueno, White Plains, N. Y. 
Last year’s collections of Heteroptera made by Mr. H. S. 
Parish in British Guiana I was fortunately able to secure, 
and the results are presented herewith. Only two papers on 
this fauna are known to me, one, published by E. P. Van 
Duzee in Trans. Am. Ent. Soc., XXVII, pp. 343-352, Dec.,

Herbert Osborn in Ohio Naturalist, V :I:195-204, Nov., 1904, 
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
