16. Head and abdomen black ; thorax black above ; stigma brown ; 



antennae, including scape, blackish 13. atratus, new species 



Head, thorax, and abdomen uniformly yellow ; stigma entirely 



yellow 14. impressus, new species 



17. Metapleurum completely punctato-rugulose ; propodeum strongly 



rugoso-reticulate ; lower part of mesopleurum depressed and 

 confluently punctate ; prepectus sculptured ; first tergite about 

 three times as long as wide at apex, ruguloso-striate, the 

 spiracles situated beyond basal fourth of tergite; posterior 

 femora longer than their coxae and trochanters combined. 



15. reticulatus, new species 

 Metapleurum mostly smooth ; propodeum finely, usually more 

 or less transversely, sculptured ; posterior femora not longer 

 than their coxae and trochanters combined 18 



18. Apex of radial cell much before wing apex; metacarpus ex- 



tending length of second intercubitus beyond apex of radial 

 cell; stigma brown, with a conspicuous pale spot at base: 

 nervulus postfurcal by not more than half its length ; third 

 abdominal tergite mostly aciculate, the lateral depressed mar- 

 gins of second tergite not wider at base than at middle 



of tergite 19 



Radial cell more nearly attaining apex of wing; metacarpus 

 not extending conspicuously beyond apex of radial oell ; 

 color of stigma, origin of nervulus, and sculpture of third 

 abdominal tergite not combined as above 20 



19. Antennae normally 45 to 50 segmented ; nervellus distinctly a 



little longer than lower abscissa of basella, the latter but 

 little longer than upper abscissa of basella ; spiracles of first 

 tergite usually before end of basal fourth of tergite; length 



usually 4.5 to 5 mm 16. canarsiae, new species 



Antennae normally 52 to 54 segmented ; nervellus not distinctly 

 longer than lower abscissa of basella, the latter nearly twice 

 the upper abscissa ; spiracles of first tergite usually distinctly 

 a little beyond basal fourth of tergite; length usually 6.5 to 

 7 mm 17. insularis, new species 



20. Clypeus very weakly convex and unusually broad, broader than 



length of second segment of antennal flagellum ; distance be- 

 tween cl}T)eal foveae fully as long as face; mandibles large, 

 stout; eyes not prominent, extending but little beyond outer 

 margins of temples ; face nearly twice as broad as long to base 



of clypeus 18. clypeatus, new species 



Clypeus normal, convex, much narrower than length of second 

 flagellar segment ; interfoveal line shorter ; eyes prominent ; 

 face much less than twice as broad as long 21 



21. Maxillary palpus with longest segment not distinctly longer than 



second segment of antennal flagellum ; stigma brown with a 

 conspicuous pale spot at base, or yellow with a distinct cloud 

 in apical half ; nervulus never postfurcal by as much as its 

 length ; abdomen varying from entirely testaceous to more or 

 less blackish at base and apex, but second and third tergites 

 always entirely pale; second tergite not distinctly longer 

 than broad at apex, usually smooth apically ; male scape not 

 swollen ^ - 22
