Male. — Typical specimen easily known by the face marks, the yellow 

 on scape, and the coarsely, shallowly, heavily punctured dorsum of 

 abdomen. 



Rather long, slender, about 6-7 mm. in length. Face long, narrow, 

 not strongly convergent below ; scape moderate, concave exteriorly ; 

 clypeus long, 2|-3 times as long as broad at base ; supraclypeal area 

 below antennal sockets quadrate. Apex of first abdominal segment 

 with usually a white fringe of pubescence. 



Sculptiire. — Front, vertex, and occiput with dense, confluent, but 

 not rugose puncturation, becoming shallower and striate on cheeks. 

 Mesoscutum closely punctured with medium sized, clear cut, round 

 punctures, somewhat smaller than those of head ; scutellum with 

 larger, more separated punctures ; metanotum rugose. Propodeum 

 normal in shape and sculpture ; bowl of enclosure with large, sub- 

 quadrate, shallow pits; lateral areas rugose to rugulose. Mesopleura 

 rather heavily punctured, with punctures larger than those of the 

 scutum, separated by about one-half the diameter of one puncture ; 

 metapleura rugose, striate. First segment of abdomen smooth, con- 

 spicuously punctured with small punctures, separated b}^ two to three 

 times the diameter of one puncture ; segment two similarly but more 

 densely punctured ; segment three and those following with punctures 

 becoming much larger, more shallow and not so clear cut, but heavy, 

 coarse, and very conspicuous ; apices of segment two and following 

 noticeably raised ; punctures of all segments more dense laterad, and 

 more sparse and shallow on venter. 



Yellow Markings. — Face marks somewhat similar to those of P. zizicF , 

 but narrower, and upper extension of lateral marks shorter and nar- 

 rower, (fig. 103) . Scape with yellow stripe in front ; labrum and mandi- 

 bles with yellow spots. A strip on each side of collar, tubercles, and 

 tegulae yellow. Legs with front of fore tibias, base and apex of other 

 tibiae, and basitarsi yellow; apical tarsi brownish. 



Genitalia. — Practically identical with those of P. modestus, (figs. 13, 

 27, 73). 



Female. — Typical specimen distinguished by the long lateral face 

 marks, long clypeus, and abdomen punctured as in the male. 



Resembles male in general form and sculpture ; face long ; clypeus 

 barely broader at base than lateral areas at same level ; narrowest 

 space between clypeus and eye relatively broad ; scape as in other 

 females, long and narrow, (fig. 139). . 



Sculpture. — Practically identical with that of male in typical form. 



Yellow Markings. — Face marks filling lateral areas, extending short
