 the Southeastern States, and from the West Indies. 



11. Genus Zaglyptus 



Figure 290,b 



Zaglyptus Foerster, 1868, Verh. Naturh. Ver. Rheinlande, vol. 25, p. 166. Type: 

 Polysphincta varipes Gravenhorst; included by Wolstedt, 1877. 



Front wing3.0 to 9.6 mm. long; body a little less long and slender than 

 most other Pimplini; face and clypeus variously colored, white to 

 black; frons sometimes with whitish orbital mark; clypeus strongly 

 convex, its apex impressed, its apical margin concave; occipital carina 

 complete, without a median dip; hair on mesoscutum moderately 

 dense, sparse, or lacking; submetapleural carina complete or incom- 

 plete; propodeum moderately long, without median longitudinal 

 carinae, with a lateral subapical tubercle which is weak in the male 

 and very prominent in the female; areolet absent; nervellus broken 

 usually above the middle but in some non-Nearctic species broken 

 near or a little below the middle; first tergite short and broad, with an 

 oblique groove on each side just beyond the middle, its median and 

 lateral longitudinal carinae present or absent; second tergite with 

 rather sharp oblique basolateral grooves and oblique apicolateral 

 grooves which together delimit a median, raised, rhombic area; third 

 and fourth tergites with strong transverse tubercles, their apical 

 impunctate band occupying about 0.22 their length; female subgenital 

 plate sclerotized apically and lateroapically, the rest membranous; 

 ovipositor straight, compressed, its tip as in figure 331,d (the basal 

 tooth enlarged and forming a long free barb) ; ovipositor sheath about 

 0.47 as long as front wing. 



Zaglyptus is worldwide in distribution but contains relatively few 

 species. Three Nearctic species are known, but only one of these is 

 widely distributed. Z. varipes attacks spider eggs as described under 

 that species. The rest of the species probably have similar habits. 



Key to the Nearctic species of Zaglyptus 



1. Carina between metasternum and metapleurum complete; abdomen black or 



more or less ferruginous 1. varipes (Gravenhorst) 



Carina between metasternum and metapleurum almost absent, present only 

 anteriorly as a short ridge or blunt tooth; abdomen white laterally, darker 

 medially 2
