44. Flagellum with a submedian white band; hind femur black; wrinkling on 



frons very weak 33. kronibeini, new species 



Flagellum entirely black 45 



45. Ovipositor sheath about 0.5 as long as front wing; basal and apical transverse 



carinae of propodeum a little closer together; hind femur black or feiTugi- 



nous ; hind coxa black or ferruginous 34. albitarsis (Cresson) 



Ovipositor sheath 0.66 to 0.91 as long as front wing; basal and apical trans- 

 verse carinae of propodeum a little farther apart; hind femur ferruginous; 

 hind coxa black 46 



46. Ovipositor about 3.0 as long from nodus to apex as it is deep at nodus; second 



recurrent vein strongly sinuate; hind femur about 5.1 as long as deep; 

 front tibia moderately swollen; front wing 5.0 to 7.3 mm. long. 



28. persimilis (Cresson) 



Ovipositor about 4.5 as long from nodus to apex as it is deep at nodus; second 



recurrent vein weakly or moderately sinuate; hind femur 6.4 to 7.0 as long 



as deep; front tibia weakly swollen; front wing 7.5 to 9.0 mm. long . . 47 



47. First abdominal tergite gradually widened near spiracles; sublateral crests of 



apical carina of propodeum small and weak; punctures on speculum sep- 

 arated by about 1.7 their diameter 24. ruralis (Pratt) 



First abdominal tergite abruptly widened just in front of spiracles; sublat- 

 eral crests of apical carina of propodeum large and prominent; punctures 

 on speculum separated by about 0.7 their diameter . 31. areolatus (Pratt) 



I. CYANATOR GROUP 



Head, thorax, and coxae with sparse, unusually long, suberect 

 hairs; temple strongly rugulose or ruguloso-punctate; frons with a 

 shallow depression dorsolaterad of antennal socket; front tarsus of 

 female not widened; areolet pentagonal, higher than Avide, its front 

 side about 0.6 as long as its mesal side; second recurrent vein simply 

 arched; axillus vein distinctly diverging from margin of hind wing; 

 abdomen black with a dull, dark blue iridescence. 



This group includes the two Nearctic species treated below (one of 

 which is Holarctic), an undescribed species from the Himalayas 

 (Gupta collection), and judging from their descriptions also the Euro- 

 pean Cry plus cyanator Gravenhorst 1829 and Cryptus balearicus Kriecli- 

 baumer 1894. Trachysphyrus cyanator and T. balearicus are new 

 combinations.
