The following brief color note was made on a male taken at Cristalina : 

 eyes above dark green, lighter below, light thoracic markings very pale 

 greenish yellow, almost white. Teneral specimens are entirely without 

 black, being dull brown with obscure paler markings. Probably all de- 

 grees of color between this dull brown and the clear bright black of the 

 fully adult specimens are passed in the life period. Specimens otherwise 

 apparently mature have been noted with traces of brown in the labrum 

 and with the black of the mesepimeron duller above, shading out into brown.

 At Cristalina, Colombia, it was associated with the much rarer magdalenae.
