MICROBRACON UICHANCOI. new species 



Closely related to lendicivorus Cushman, from the foregoing de- 

 scription of which it differs as follows: Smaller; width of face less 

 than one and a half times as long as diameter of eye; malar space 

 subequal to basal width of mandible and much shorter than width 

 of mouth opening ; antennae filiform, not tapering from before mid- 

 dle, subapical joints distinctly less than twice as long as thick; basal 

 joint of hind tarsus not so long as rest combined, third distinctly 

 longer than fifth; median ridge of abdomen fading out on fourth 

 tergite; second tergite irregularly rugose, others opaque punctate. 

 Head and thorax paler ; stigma stramineous ; hind coxa entirely pale 

 testaceous; abdomen nearly uniform pale testaceous, apices of ter- 

 gites only slightly paler, suturiform articulation and sometimes a 

 stain on each side of middle of second tergite blackish; sheath only

 Considering the wing to have three cubital cells it runs to couplet 4, 

 where it agrees with the first alternate in the apically open second 

 cubital cell, but disagrees in its possession of discal veins in the hind 

 wing. Under couplet 5 it agrees with both characters attributed to 

 Micraulacinus Kieffer. Following the lead of the second alternate of 

 couplet 1 it agrees with neither alternate of couplet 9 because the
