1. LEUCOSPIS SLOSSONAE. new species. 



The manuscript name of slossonae given this species (male and 

 female) by Ashmead has been retained in the following description.

 hind femur, but differs in sculpture of face ; darker color of wings ; 

 body markings and teeth on under side of hind femur. There is no

 texana both male and female have a faint carina.

 markings; face long and narroiv; ovipositor very short; teeth on 

 hind fe^nur feio and large. 



Body black with following parts reddish-orange: scape; first six 

 segments of flagellum especially on underside; two small dots on 

 vertex near lateral margin of scrobe ; wide band on posterior half of 

 pronotum which extends forward laterally as two large spots; nar-

 base of front wings ; crescent-shaped band on scutellum ; metapleurae ;
