>A 24. Bracon democraticus. (Tab. xiii. fig. 19.) 



JFerrugineiis ; antennis, capite pedibusque, nigris ; alis fuliginosis, stigmate nigro. 

 Long. 7 millim. ; terebra 5*5 millim. 



Hab. Mexico, Northern Sonora (Morrison). 



Face finely and closely punctured, a semicircular, shining, impunctate space over the 

 clypeus; the depression over the antennae shallow, the furrow narrow. The two 

 furrows of the petiole punctured somewhat closely, and of nearly equal width. Second 

 segment coarsely and longitudinally striated (some of the striations being much stronger 

 than others), a smooth, shining, impunctate, triangularly shaped space at the base, the 

 apex shining and impunctate ; third segment longitudinally striated like the second, 

 the fourth segment broadly so in the middle ; the suturiform articulation broad, longi- 

 tudinally striated. The abdomen is scarcely so long as the thorax, the petiole at the 

 base is semiperpendicular. The recurrent nervure is received a little in front of the 

 transverse cubital nervure. 



}C 25. Bracon comparatus. 



Luteus; antennis, femoribus tibiisque posterioribus, nigris; alis fumatis, stigmate testaceo. <$ . 

 Long. 8*5 millim. 



Hab. Mexico, Northern Sonora (Morrison). 



Antennae tapering towards the apex, originating from distinct tubercles ; basal joint 

 a little more than three times the length of and one half thicker than the second, the 

 apex obliquely truncated ; the joints of the flagellum indistinctly separated ; third and 

 fourth joints subequal. Face shining, impunctate ; front but slightly depressed above 

 the antennae. Metathorax with a gradual slope to the apex. Abdomen nearly double 

 the length of the thorax, sessile ; petiole one half longer than the second segment ; flat, 

 the central part tongue-shaped (not reaching to the apex of the petiole), the apical 

 part narrower and keeled in the centre, the furrows shallow; the first transverse 

 furrow is indicated, but not very distinctly; the petiole is shining, impunctate, the 

 rest indistinctly reticulated. 



26. Bracon crudelis. 



Luteus ; femoribus, tibiis tarsisque pro majore parte antennisque, nigris ; alis fumatis, stigmate fusco ; artieu- 



latione suturiformi recta, striolata. 

 Long. 7 millim. 



Sab. Mexico, Northern Sonora (Morrison). 



Antennae as long as the body, nearly glabrous, the joints distinctly separated; basal 

 joint three times as long as the second, slightly curved beneath, the apex semiobliquely 

 truncated ; third joint a little longer than the fourth. Face shining, obscurely punctured ; 

 front depressed above the antennae, the furrow not very deep ; ocelli surrounded by a
