136 HYMENOPTERA. 



Genitalia. — Very similar to P. modest us and episcopalis, but arma- 

 ture longer and heavier, especially stipites, (figs. 14, 28). 



Female. — Recognized by its coarse puncturation, large, long, lateral 

 face marks, yellow on collar, and impunctate abdomen with red basal 

 segment. Slightly larger than the male which it resembles in form. 



Sculpture. — Puncturation as in the male, exceedingly coarse and 

 heavy thruout. Propodeum lacking the fossa of the male, but coarsely 

 pitted at base ; neck of enclosure narrow forming a groove. Abdomen 

 as in the male. 



Yellow Markings . — Very conspicuous , lateral face marks filling 

 lateral areas and extending well above base of antennae, terminating 

 abruptly on eye margin. Entire collar except small space in center, 

 tubercles, spot on teguhe, front of fore tibiae, base of middle tibia;, 

 practically all of hind tibiae, and all tarsi yellow. 



Habitat. — Unique male type from Louisiana, in collection of 

 C. F. Baker, (No. 2336). Unique female from Alabama, in 

 collection of C. F. Baker. (No. 2296). No other data given. 



There is no chance for confusing this with any other species 

 known to me. The T;oarse, dense, pit-like punctures over 

 entire head and thorax, with the immense, deep fossa of the 

 propodeum of the male, the great pits and ridges of its lateral 

 surface, and the comparatively narrow, V-shaped enclosure 

 entirely on the superior face, are found in none of the other 

 species, and serve to distinguish it at a glance. The species 

 described by Robertson as P. fiehonbonismsiy possibly be the 

 same as this if the red basal segment of the abdomen is char- 

 acteristic, as this is the distinguishing feature given for that 

 species. However, as there was nothing else given in the 

 description to indicate relationship there is no way of decid- 

 ing until Robertson's specimens are redescribed. So far as 

 I know no description of the male of P. ne/nmbo?iis has been 

 given, altho it has been mentioned in print. If Robertson 

 had specimens of this species it is almost inconceivable that 

 some of the sculptural characters should not have been men- 

 tioned, so there is little possibility of the two being the same. 



THE ASININUS DIVISION. 

 The genital characters separating this from the other divi- 

 sions are based principally on the seventh ventral plate, 

 which is of an entirely distinct form. The wings of this plate 

 as a rule have a broad, more or less quadrate body, invagi-
