PronotK77i, as seen from ahove^ with a deep snhapical notch in each 

 side (pi. 25, fig. 5). 



Forewing of males 4.5-8.5 mm. long, of females 6.5-11 mm. long; 

 temple polished, with a few fine punctures ; pronotum polished, weakly 

 swollen subbasally, medially and subbasally with irregular coarse cross 

 ridges and subbasally with some large indistinct punctures ; pronotum 

 subapically with a large dorsal quadrate impression that connects on 

 each side with a very deep notch (pi. 25, fig. 5) ; mesopleurum polished, 

 with large round punctures separated by about 0.4 their diameter; 

 brachial and subdiscoidal veins usually distinct, sometimes obsoles- 

 cent in small specimens; outer face of hind femur mat, subpolished 

 basally; hind tibia of female pinched sharply at its basal 0.4, beyond 

 which it is swollen to 0.8 the width of the hind femur, its inner face 

 somewhat indented at the apical 0.4 ; hind basitarsus of female rather 

 narrow, weakly expanded apically; first tergite jjolished, with close 

 interrupted cross ridges, in the female about 9.0 as long as w^ide; 

 ovipositor sheath about 1.12 as long as the body. 



Blackish brown, or sometimes more or less dark ferruginous, the 

 ferruginous most often restricted to the head and fore part of the 

 thorax but sometimes covering the entire body. Cheek mostly stra- 

 mineous ; antenna, hind margin of pronotum, tegula, front and middle 

 legs, hind trochanters, and basal 0.33 of hind tibia usually paler than 

 the ground color, often brownish ferruginous; wings subhyaline; 

 ovipositor sheath with a white preapical band. 



This species occurs in mesic woods from Ontario to Florida, west 

 to Iowa, Texas, Arizona, Utah, and southern California. On the basis 

 of color it is divisible into two subspecies, the typical subspecies occu- 

 pying the Lower Austral and Tropical Zones of the Southeastern 

 States, and tlie other subspecies the rest of its range.
