disc of the dorsulum and scutel are less punctured and more polished 

 and that the abdomen above isv polished and less punctured as well as 

 less distinctly punctured. First joint of flagel distinctly longer than 

 either the second or third joints, but shorter than these two combined 

 and just about as long as the fourth. The fourth and following 

 joints almost equal in length, excepting the apical joint, the longest 

 side of which is distinctly though not much longer than the cor- 

 responding side of the joint preceding it. The apical joint is obliquely 

 truncate at tip. The truncature smooth and polished ; mandibles so long 

 that the tip of a completely flexed mandible would extend almost 

 to an imaginary vertical line drawn tangent to the outermost edge 

 of the eye ; the inner margin provided with a rounded tooth near 

 the middle, beyond which there is an emargination and then an 

 arcuate edge to the tip ; labrum polished and rounded ; malar space 

 present and distinct, rather quadrate, and as long from eye to mandible 

 as is the first joint of the flagel; ocelli in an arcuate row, the lateral 

 ones a little nearer to each other than to the nearest eye margin; first 

 recurrent vein received by the second submarginal cell a little before the 

 middle. Otherwise virtually as in Melitta americana.

 clypeal distance ; cheeks rounded and about as wide as the eyes as seen

 undulate ; clypeus transverse, nearly twice as wide as long, shining some-
