 Guatemala, Lanquin in Vera Paz (Champion) ; Nicaeagua, Chontales (Janson) ; 

 Panama 1 (Boucard), Volcan de Chiriqui 2500 to 4000 feet, Caldera (Champion), 

 Chiriqui \ 



An example from the Volcan de Chiriqui has the body of a decidedly greenish tinge, 

 with hardly a trace of blue, the wings also being much duller in tint and having an 

 obscure greenish tinge. 



The male is similarly coloured to the female, but the nagellum may have the luteous 

 colour obscured; the clypeus does not gape so much, and has the incision at the apex 

 angled in the middle ; the tufts of hair on the fifth abdominal segment are short, very 

 stiff, and closely pressed together ; the sixth segment is thickly covered with black hair, 

 and is roundly incised at the apex. Above, the apical two segments are covered with 

 short black hair. 



The male of the above-mentioned greenish form from Chiriqui has the antennae of a 

 brighter colour, and the base of the nagellum may be black.

This species has the apex of the clypeus rather deeply arcuate, and, like the labrum, 

 finely and closely punctured ; the median segment at the base and apex bluntly tuber- 

 culate, this being also the case with the mesopleurse ; the fifth ventral segment with a 

 tuft of long, black, soft hair on either side ; and the third transverse cubital nervure 

 elbowed.
