Tlie present series shows marked variation. Those from Cin- 

 cinnati and Jiminez have the pronotum distinctly more elongate 

 (4.7 and 4.8 mm.) and slightly more slender than in the San 

 Antonio series (pronotal length, 3.9 to 4.2 mm.). This may be 

 of specific or racial diagnostic importance. In three Costa 

 Rican males l)efore us of the very closely allied, if not synony- 

 mous, P. inf'uscatn Saussure and Zehntner, variation is also found 

 (pronotal length, 3.6 to 4.3 mm.), but in these the diameter is 

 proportionate to the length, the proportions being as in the San 

 Antonio series of bogotensis. The extremes of tegminal length 

 (19.7 and 21.2 mm.) are found in the San Antonio series, the 

 marginal field also varying in width (1.5 to 2 mm.). 



No granulations of the facial scutellum are shown by any of 

 the material at hand. This is a feature described by Saussure 

 for the type of bogotensis. In other respects the series is per- 

 fectly typical, and we believe that a smooth and feebly tri-svilcate 

 facial scutellum will be found to be the normal condition in 

 bogotensis. It is clear that bogotensis and infnscata arc very 

 closely related, and that the latter name may prove to be synony- 

 mic, or at best of only racial value. Saussure and Zehntner, over- 

 looking priority, suggest that bogotensis might represent a variety 

 of their injuscata. 



The spine of the lower ocellus, characteristic of the genus, is 

 similarly developed in specimens of these species and in para- 

 types of guyanensis Chopard, now before us.
