Eulema fallax, Smith, Cat. Hym. Ins. Apidce, ii. p. 381, S • 

 Hah. Para. 



This species is very closely allied to ^^ surinamensisy'' of 

 which it may possibly be a variety. It has, however, no 

 yellow markings on the face, as in the male of that species, 

 which has a narrow longitudinal line down the middle of the 

 clypeus, two spots at its anterior margin, and usually a minute 

 spot on each side about the middle of its margin ; there is also 

 a spot on the face opposite the insertion of the antennae : the 

 male of E. fallax has the face, the thorax anteriorly, and the 

 tegular bright green, and the abdomen is entirely clothed with 

 fulvo-ochraceous pubescence; in "surinamensis^^ the basal 

 segment is covered with black pubescence.

Having examined a very large number of examples, I have 

 come to the conclusion that it is a species that runs into great 

 variety of coloration, the majority being of a vivid green ; 

 others have a golden lustre ; then others are blue, or blue 

 with shades of purple ; some have the head and thorax blue, 

 with the abdomen pm-ple ; the most beautiful variety is 

 that with the head and thorax purple, and the abdomen bril- 

 liant carmine : these and other mixtures of coloration occur. 

 E. analis of Westwood is a beautiful variety : tlie head and
