Apophyses short medialbus Cushman, female (Brazil). 



64. Margin of mesoscutum not white 65. 



Margin of mesoscutum white 76. 



(acouratus Cresson, female [Mexico]. Point not definitely covered 

 in description : " two short lines on each lateral lobe of mesothorax." 

 Popodeum red and black.) 



65. Propodeum red or red and yellow, not at all black 66. 



Propodeum red and black or black and yellow : 71. 



66. Propodeum red and yellow rufomaculatus Cameron, male (Cuba). 



Propodeum with at most the apophyses yellow 67. 



67. Face black erythrosternus Cameron, female (Panama). 



Face white 68. 



68. Orbits entirely white 69. 



Orbits not entirely white 70. 



69. Second tergite black in basal middle manni Cushman, female (Bolivia). 



Second tergite with an elongate oval white spot in basal middle. 



circumfluens Cushman, female, male (French Guiana). 



70. Posterior orbits black with a white spot ; apophyses very long and curved. 



copiosus Cresson, female, male (Mexico). 



White orbital ring interrupted only at bottom of eye; apophyses short, 



straight confusus Cushman, female (Mexico). 



71. Propodeum red and black 72. 



Propodeum black and yellow 75. 



72. Apical carina of propodeum present. 



pallidibalteatus Cameron, female (Mexico). 

 Apical carina wanting 73. 



73. Propodeum with a median ,black stripe ; hind femora red. 



areolaris Cushman, female, male (Panama). 

 Propodeum transversely black before carina; hind femora black 74. 



74. Hind femur black only above; occipital carina not meeting hypostomal 



carina cockerellae Viereck, female (Guatemala). 



Hind femur entirely black ; occipital carina meeting hypostomal carina. 



mediotinctus Cushman, female (Honduras). 



75. Propodeum black only at base trochanteratus Szepligeti, female (Brazil). 



Propodeum with three longitudinal black stripes. 



trilineatus Brull6, female (not male) (Guiana) (See 92). 



76. Propodeum not at all black 77. 



Propodeum more or less black and piceous 78. 



3 Szepligeti's determination of nigroscutellatus is apparently wrong. Brull6's type 

 female is said to have the apophyses short while Szepligeti's male is said to have them 

 long. The usual antigeny is the reverse of this.
