 and thorax is black, no trace of color except the propodeum has a very 

 faint greenish reflection; abdomen black with faint blue reflection, the 

 first tergite dark yellowish or brownish on sides and ventral surface, 

 and the seventh tergite with a white spot ; coxae all black, extreme apex 

 slightly yellowish; trochanters black with more of their apex yellowish ; 

 all femora, tibiae, and basal tarsal joints yellowish, the last two tarsal 

 joints of foretarsi and last four joints of last two pairs, dark; clypeus 

 truncate in front (very slightly concave) with a narrow rim in front 

 which is black on middle third, 2.4 times as broad as long; head 1.25 

 times as wide as long; middle interocular distance 0.52 times the 

 transfacial; upper interocular distance (80) equal to the lower; the 

 ratio of lengths of first four antennal joints is 40:13:55:55; lateral 

 ocelli 2.0 times as far from ej^es as from each other; face, clypeus, 

 ventral surface of coxae, sides of thorax, and about posterior third of 

 propodeum (actually most of propodeum in certain reflected light) 

 silver}^ sericeous; basal half of mandibles black apical half j^ellow, as 

 are all the mouth parts; wings hyaline but slighth^ bro^^^lish, veins and 

 stigma rather dark.
