clypeus, the second joint of the flagellum about half as long again as the 

 third, eyes almost parallel ; posterior-ocelli about half as far again from 

 the eyes as from each other. Mesopleurse without tubercles ; first 

 abdominal segment fully half as broad again as long; second ventral 

 segment without a raised area at the base ; pygidial area narrowly rounded 

 at the apex, gradually narrowed from the base, a little less than twice as 

 long as the greatest breadth. Very finely and not very closely punctured, 

 enclosed area at the base of the median segment minutely punctured 

 at the apex, finely striated at the base. First recurrent nervure received 

 a little before the middle of the second cubital cell. 



S . Clypeus convex, shining, longer than broad, truncate at the apex. 

 Antennae inserted only a little fvirther from the anterior ocellus than from 

 the base of the clypeus, apical joint of the flagellum shorter than the 

 penultimate. First recurrent nervure received just before one-third from 

 the base of the second cubital cell. 



Habitat— K2iB\mrix, 6-6,000 ft. (Nurse). May, 



Cerceris onellicula sp. n. 



$ . Ochracea ; fronte circa ocellos, mesonotoque nigris ; prothorace, 

 scutello postscutelloque flavis ; alls hyalinis, apice infumatis ; clypeo leviter 

 emarginato, segmento mediano area basali nitida, area pygidiali apice 

 leviter emarginata. 



Long. 9 mm. 



Clypeus nearly as long as the breadth at the apex, feebly emarginate 

 on the apical margin, slightly convex, shining, with a few scattered punc- 

 tures. Head closely but not deeply punctured, the front below the 

 insertion of the antann^e almost smooth. Eyes parallel on the inner 

 margin ; second joint of the flagellum distinctly longer than the third ; 

 breadth of the cheeks equal to about half of the greatest breadth of the 

 eyes. Thorax sparsely punctured, the scutellum almost smooth ; pronotum 

 slightly depressed in the middle ; mesopleurse with a minute tubercle. 

 Median segment and abdomen rather closely punctured ; the enclosed area 

 at the base of the median segment smooth and shining, with a shallow 

 median groove, which is continued more deeply to the apex of the seg- 

 ment. First abdominal segment a little broader at the apex than long ; 

 second ventral segment without a raised area at the base ; apical margin of 

 the fifth ventral segment very slightly raised. Pygidial area half as long 

 again as the breadth at the base, where it is broadest, nearly twice as long- 

 as the breadth on the shallowly emarginate apical margin. First recurrent 

 nervure received at one-third from the base of the second cubital cell. 

 Ochreous ; the front round the ocelli broadly and the mesonotum black ; 

 pronotum, pleurpe, scutellum and postscutellum yellow. Wings hyaline, 

 strongly infuscated beyond the radial cell, nervures black.
