For in Stigmns, and allies, the second recurrent nervure is 

 wanting; and the presence or absence of a recurrent nervure 

 is of far greater importance than the presence or absence of 

 one of the transverse cubiti. As far as known the habits of 

 the two subfamilies are much the same. 



The above remarks should justify the uniting of Psen and 

 Pemphredon in the same family. 



Psenulus (Neofoxia) sayi, new species. 



Belongs near tibialis Cress., but the sculpture of the dorsu- 

 lum is not as strong, the mesopleura is sparsely punctured, 

 not striato-punctate, the head more shining, and the abdomen 

 with a broader red band. 



Female Length (i mm. Anterior margin of clypeus gently rounded, 

 not dentate or notched; front closely punctured, vertex and posterior or- 

 bits shining and very sparsely punctured, carina from anterior ocellus 

 complete and distinct; a depression beside each lateral ocellus; dis- 

 tance between the lateral ocelli slightly greater than the distance between 

 one of them and the nearest eye margin; flagel robust, the first joint 

 slightly longer than second; dorsulum and scutel with distinct, well sep- 

 arated punctures; mesopleura similarly punctured; enclosure well de. 

 fined, with some oblique stria*; furrow of the posterior face deep; rest 

 of the metathorax finely striated, with a tendency to reticulations on the 

 sides; third transverse cubitus sinuose; second cubital narrowed about one" 

 half above; femora robust; abdomen elongate, petiole shorter than the rest 

 of the segment, flattened above: pygidium narrowed slightly apically, 

 finely granular. Black; flagel beneath and tegulaj testaceous; four ante- 

 rior tibiae and tarsi, hind tibiae and tarsi at the base whitish; all of the 

 second and third abdominal segments bright red. Wings clear hyaline, 

 iridescent; venation dark brown. 



Type locality : Onaga, Pottawatomie County, Kansas(Creve- 

 coeur). 



Type: No. 12356, U. S. National Museum. 



This is the species recorded as Mimesa pauper from Texas 

 by Cresson in Hymenoptera Texana, but it is much different 

 from that species, in venation and sculpture as defined by Fox 

 and Packard. 



Psenulus (Neofoxia) brevipetiolatus, new species. 

 Very distinct in the short petiole and simple clypeus. 



Female. Length !> mm. Middle of the anterior margin of theclypens 

 truncated, the sides rounded, without teeth; a line-like furrow from ante- 

 rior ocellus to base of clypeus; front finely granular; vertex and posterior
