and adjacent portions of wings when at rest very dark and sug- 

 gesting a suffused continuation of the medio-dorsal stripe, hya- 

 line portion of wings iridescent and wing veins burnt hike (in 

 this respect suggesting the otherwise distinctive ('. iriodes). 

 Genicular areas of caudal femora apically darkened. A darker 

 phase of the species also occurs in which the green color is sup- 

 planted by yellowish brown. The female resembles the male in 

 coloration excepting that the abdominal colors are much paler 

 and more indistinct. 



The localities given below and those of the type series define 

 the known distribution of the species. 



In addition to a paratypic pair from Gualaquiza, Ecuador, \vc havo had \h'- 

 fore us the following series of 38 specimens; 15 males and 23 females.

The description of saltator is very brief, but, although we iiave 

 been unable to examine the type, \\c are convinced that it con- 

 stitutes the basis of the present species. The present insect is 

 the dominant species in the Guianas, tlie only other form found 

 there to which could apply Saussure's very bric^f description being 

 macropterous C. cinereus, which speci(>s we have from ("ayeime,
