AQUATIC RHYNCHOTA 



collecled by D r E. Festa in Darien d- Venezuela. 



1. Uliagovelia angustipes Uhi. 

 Macropterous and apterous forms. 



Darien — Foreste laguna della Pita; Venezuela — Rio do paso reni, 

 Puerto Gabello; Macuto la Guayra. 



I caunot separate these examples from R. angustipes Uhi., the type 

 of "which I have examined. The posterior femora are, perhaps, a little 

 more strongly spinose and the pronotum is distinct from the mesonotum 

 in the apterous individuai, as also in a nymph. 



2. Ftliagovella fetnoralis Champion. 

 Apterous <f 5 5 and nymphs. 



Venezuela — Rio do paso real, Puerto Cabello. 



I have determined these specimens as above, although they do not 

 quite agree with the description. Champion describes the antennae as 

 comparatively short, the first segment about twice as long as the second, 

 2-4 subequal in length. In these Venezuelan examples the exact pro- 

 portions are 48:27:20:25, the third being distinctly (*) shorter than 

 2 or 4. The pronotum is distinct from the mesonotum and there is no 

 trace of carination on the venter. 



3. Corlxa pygmaea (Fieb.). 

 d j Imagines; nymphs. 

 Columbia — Sabanilla. 



4. Anisops elegans Fieb. 

 Imagines & nymphs. 



Darien — Laguna della Pita. 



O AH ruy propor lionate measuremeuts have been made by employing an 

 eye-piece miciometer and a compound microscope, first of ali with a two-inch 

 objective, the results being checked by employment of a one-inch objective.
