pronotum, at this point ending at or becoming obsolete in a vertically 

 elliptic, white, slightly raised callus; punctures on mesopleurum mod- 

 erately coarse, strong, separated by about 0.25 their diameter; apical 

 transverse carina of propodeum unusually close to apex of propodeum, 

 rather weak, in the male usually with a brief median interruption, in 

 the female with a moderately wide median interruption, its sublateral 

 part rather strongly oblique and not elevated as a crest; areolet about 

 1.5 as wide as high; second tergite moderately mat, its punctures 

 small, separated by about 1.5 their diameter; ovipositor sheath about 

 0.80 as long as front wing; ovipositor tip about 11.5 as long from nodus 

 to apex as it is deep at nodus. 



Male: Black. Face, cheek, and clypeus white except for a narrow 

 oblique blackish mark over each clypeal fovea; orbit white except for 

 an interruption on upper part of temple; mandible white; palpi pale 

 brown, their first two segments largely white; flagellum rarel}^ with an 

 obscure dorsal whitish mark on one to thi'ee of its median segments; 

 lower third of propleurum, upper and lower margins of pronotum, 

 median spot on mesoscutum, basolateral carinae of scutellum, sides 

 and apex of scutellum, postscutellum, tegula, subtegular ridge, usually 

 a longitudinal mark on mesopleurum just above sternaulus, elliptic 

 spot at upper end of prepectal carina (this often confluent with white 

 mark on subtegular ridge and mark on lower part of mesopleurum), 

 much or most of mesosternum, upper part of mesepimeron, and apical 

 corner of metapleurum, white; mesopleurum often with a median 

 ferruginous area; metapleurum varying from entu-ely ferruginous to 

 entirely black; propodeum varying from black with an apicolateral 

 ferruginous mark to mostly ferruginous with its base broadly infus-

Female: Colored lilve the female of M. thoracicus except that the 

 ground color is fulvoferrugiuous rather than fulvous, there is always 

 a white mark at upper end of prepectal carina, often a short but broad 

 oblique white stripe just above sternaulus (often joining with white 

 mark at upper end of prepectal carina), usually a short but broad 

 white stripe just below sternaulus, trochanters and front and middle
