PEDIES Saussure.

Careful study of the literature and study of. the specimens dis- 

 cussed below, proves to our full satisfaction the above synonymy. 

 Saussure's description, though very brief, gives nearly all the features 

 of importance. The efforts of Scudder and Bruner to locate Pedies 

 virescens, the genotype by monotypy, have been decidedly incorrect^ 

 their supposition being that the position of the species was near 

 Dactylotum. At the time Paradichroplus was described Brunner 

 ignored the genus Pedies. 



We would note that, from material before us, three species, mexi- 

 canus (Brunner), variabilis (Bruner) and andeamis (Caudell), in 

 addition to the genotype, are referable to Pedies; but that nigrigena 

 Rehn and hrunneri, jusijormis and bipundatus all of Giglio-Tos, 

 assigned originally to Paradichroplus, can not properlj^ be placed in 

 the present genus. 



Striking features in the genus Pedies, as given by Saussure, are: 

 the strongly declivent and convex face; the sub-bicarinate frontal 

 costa; the conoid-arcuate apex of the head; the pronotum with strong 

 percurrent median carina cut weakly by the principal transverse 

 sulcus, with distinct percurrent lateral carinse and with caudal margin 

 distinctly emarginate, and male genitalia of the characteristic type 

 found in Dichroplus and allied genera.^ 



Pedies mexicanus (Brunner).

An additional dried alcoholic female from the United States 

 National Museum, without exact data, is at hand. 



The prosternal spine in this insect is broadly truncate, cuneiform. 



** This genus was described without type designation; the type by first subse- 

 quent fixation is Platyphyma mexicanus Brunner, selected by Kirbv, Syn. Cat. 

 Orth., Ill, p. 492, (1910). 



^ Certain of these features are not indicated in the aberrant P. variabilis 

 (Bruner), see p. 254.
