POMPILID^. 



7. Pepsis c^eulea Linu., 5 . 



8. Ceeopales texana Cress., c?. 



These specimens agree well -witli the brief description of the species, 

 but there is a fine white line on the posterior orbits, and the white spots 

 at the base of the abdomen are on the first segment and not on the 

 "second." This is probably the male of nigripcs Cress. 



9. POZMPILUS ichneibioniformis n. sp., 2 . 



Length 10'™. Elongate; pale ferruginons with yellow marlcings ; face 

 yellow, clypeal sutnre, space about ocelli, a hne connecting it with the 

 top of the eyes and a forked line (bounded by ferruginous) connecting it 

 with the insertion of the antenn?e, black; clypeus truncate, narrowly 

 bordered with ferruginous, and with a quadrate ferruginous spot, broad 

 posterior orbits yellow; antennte ferruginous, scape yellow beneath, 

 fifth and following joints black above; labrum cleft, the epipharynx

 the claws of the anterior tarsi with the tooth a little beyond the middle, 

 the other claws with the tooth at the middle. All the s])ines of the

 the marginal and smaller than the second submarginal cell ; siibmcdial

 externo-medial nervure. Abdomen with the extreme base of the first 

 segment and the visible seventh dorsal segment* black ; narrow borders 



*Iu rompihis the sixth veutral is longer than the sixtli tlorsal, and there is present 

 a membrauons piece filling up the space thus left vacant ; in Aocnia the sixth ventral 

 is also longer than the sixth dorsal, hut the space is only partially filled by the piece
