THE TRIBE CHALCIDINI — BURKS 325 



Propodeum thickly covered by irregular, closely set caidnae, areas 

 between carinae minutely reticulated, lateral propodeal projections 

 wanting, spiracular openings nearly vertical ; petiole short, less than 

 twice as long as wide, minutely shagreened on dorsal side near base, 

 slightly more strongly shagreened on lateral and ventral sides, basal 

 lamina narrow, strong lateral carinae present; gaster compressed, 

 usually somewhat shorter than metafemur, abdominal tergites 4 to 7 

 with lateral setae; eighth tergite minutely shagreened, sparsely cov- 

 ered by long setae, spiracular openings round; cerci oval, located 

 slightly nearer anterior than posterior margin of epipygium ; apex of 

 ovipositor sheath with a dense tuft of long ventral setae. 



Male: 4.5-5.5 mm. Antennal scape (fig. 9, i) stout, sinuate; width 

 of malar space one-fourth height of compound eye ; combined widths 

 of compound eyes two-thirds width of interocular space at level of 

 antennal bases ; imier tooth of metafemur blunt ; petiole varying from 

 slightly more than one-third to one-half as wide as long. 



Type locality. — Texas. 



Types.— Hoiotype, male, 1436, U. S. National Museum. The female 

 was described as Smicra hioculata Cresson, from Texas; types: hi- 

 oculata Cresson, 1784, Academy of Natural Sciences of Philadelphia, 

 and 1652, U. S. National Museum ; Uoculata faceta Cresson, 1653, U. S. 

 National Museum. 



The types of S. subolsoleta Cresson and aS'. hioculata Cresson show 

 distinct color differences, but intermediates between the two are readily 

 found ; they differ structurally in that hioculata has the apex of the 

 metatibia rather blunt, while it is acute in suhobsoleta. All varia- 

 tions between these two extremes were found in the material secured 

 for study, and one specimen was found which had one tibia acute 

 and the other blunt. The type of JS. hioculata faceta has the yellow 

 spots very light, but is otherwise identical with the typical form of 

 this species. 



Host. — Unknown. 



Distrihution.—ColovQido, Florida, Illinois, Iowa, Kansas, Montana, 

 North Dakota, South Dakota, Texas, Wyoming.
