supposedly adult and, in consequence, very distinctive insect. 

 Bruner's synonymic genus and three synonymic specific names are 

 entirely attributable to Scudder's error and the remarkable color 

 variation found in the species. 



The males are either brilliant green, marked with buff, or brown 

 with a greenish_ suffusion, marked with buff; the females are either 

 solid and almost immaculate brown or green, marked with buff. 

 The caudal tibia and tarsi of the males are entirely jasper red to 

 scarlet red, or this color only in the distal third or two-fifths of the 

 tibige, the remaining proximal portion being light terre verte or 

 porcelain blue. The females have the caudal tibiae and tarsi usually 

 much less brilliantly colored, entirely reddish, or bluish, changing 

 gradually through purplish to reddish chstad. The dorso-lateral 

 pale lines of the pronotum are striking only in the green condition of 

 both sexes, these vary in width and are sometimes abruptly terminated 

 at the principal sulcus. None of these types of coloration have any 

 further significance than the adaptation of the individual to local 

 vcnvironmental conditions.

The series now before us, incluchng the single types of all the 

 •described species, prove beyond question the above synonymy, the 

 features given by Scudder to distinguish these genera being fanciful 

 or of no generic value. 



The genotype, Conalccea ■miguelitana Scudder, is closely related to 

 ■Conalccea huachucana Rehn, the latter may eventually prove to be a
