AQUATIC RHYNCHOTA 



cotteci ed by D r E. Festa in Darien & Venezuela. 



1. liliagoveìia angustipes Uhi. 

 Macropterous and apterous forms. 



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

 Puerto Cabello; Macuto la Guayra. 



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

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

 more strongly spinose and the pronotum is distinct from the mesonotum 

 in the apterous individuate, as ateo in a nymph. 



2. .Rliagovella femoralis Champion. 

 Apterous cT 9 9 and nymphs. 



Venezuela — Rio do paso real, Puerto Cabello. 



1 bave 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 Iength. 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.). 

 e? j Imagines; nymphs. 

 Columbia — Sabanilla. 



4. Anisops elegans Fieb. 

 Imagines & nymphs. 



Darien — Laguna della Pita. 



(*) Ali my propor 'lionate measurements bave been macie by employing an 

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

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