73. spongiosa Bugbee 



41. Sixth abdominal tergum about as long as four and five combined; median 



furrow of propodeum narrows toward base . . . 74. obtusa, new species 



Sixth abdominal tergum narrow, very little longer than fifth; median furrow 



with approximately parallel lateral carinae . . . 75. imminuta Bugbee 



42. Ocellocular line distinctly longer (approximately twice) than diameter of 



lateral ocellus 76. bolteri Riley

 lateral ocellus 43 



43. Dorsal valves of the female genitalia broad for horizontal length; propodeum 



with a narrow median furrow outlined by lateral carinae to base of pro- 

 podeum; tegula black 77. spina Bugbee 



Dorsal valves of female genitalia narrow for horizontal length and only 

 slight dorsal extension of dorsal and ventral valves; propodeum variable, 

 wide, and shallow without median furrow or incomplete median fur- 

 row 44 



44. Marginal vein broader than postmarginal vein; all veins brown .... 45 

 Marginal vein linear and about same width as postmarginal; veins pale 



yellow _ 46 



45. Sculpturing on lateral surface of sixth tergum limited to lower half or less; 



dorsal surface smooth and shiny; femora and tibiae with black infuscation. 



78. picea, new species 



Sculpturing on sixth covers most of lateral surface but may disappear or 



continue over dorsal surface; femora and tibiae often yellow or with some 



brown infuscation 79. calcarea Bugbee 



46. Basic color of legs yellow with varj'ing amounts of black or dark-brown 



infuscation on middle and hindtibia and femora; marginal vein longer

only; sculpturing on lateral aspect of sixth abdominal tergum limited to 



lower half 81. mali, new species 



Forelegs often yellow or with black infuscation on femora; black infuscation 



on mid- and hindfemora and tibiae; lateral sculpturing on sixth abdominal 



tergum usually covers lower half completely and then diminishes toward 



anterior margin to just below dorsal surface . . . 82. diastrophi Walsh
