tibiae dark brown ; facial pubescence slightly yellowish ; thoraxic pubes- 

 cence silvery; wings slightly dusky iridescent; venation dark brown. 



Type locality: Catnden County, N. J., August 6, 1890. Col- 

 lection of W. J. Fox. 



Type No. 12,859 U. S. N. M. 



On account of the short petiole this species falls in with 

 basirufa Cress, and proximo, Cress., but will be separated at 

 once by the absence of a rufous band on the abdomen. The 

 female of maculipes Fox is undescribed, and pcrple.va is very 

 like what we may expect this female to be, yet there are so 

 many differences that perplexa seems distinct from the Florida 

 species. 



Pemphredon Cereonus harbecki n. sp. 



Allied to bipartator Fox, but may be distinguished by the 

 sparser punctures of the head and dorsulum, the small enclo- 

 sure of the metanotum, the presence of a furrow on the petiole 

 above, and in having the petiole longer, the emargination of 

 the clypeus is narrower and more sharply defined than in 

 bipartator which has the emargination sloping at the base, 

 instead of the basal wall being perpendicular. 



$. Length 7.5 mm. Clypeus with a deep semi-circular emargination; 

 mandibles not punctured basally ; clypeus, supraclypeal area, vertex and 

 posterior erbits shining with distinct, well separated punctures ; front 

 striato-punctuate ; distance between the lateral ocelli distinctly less 

 than the distance from one of them to the nearest orbital point; third 

 antennal joint distinctly longer than the fourth; dorsulum and scutel 

 with widely separated, distinct punctures; mesopleurae irregularly, 

 transversely striato-punctate ; enclosure of the metathorax rather 

 small, with some strong longitudinal striae laterally, centrally reticu- 

 late; the shining area bounding the enclosure large; sides and posterior 

 face of the metathorax punctato-reticulate ; petiole two-thirds the 

 length of the hind femora, with separate punctures and a deep middle 

 furrow above ; legs and abdomen normal ; second recurrent nervure 

 interstitial with the first transverse cubitus. Entirely black ; hair gray ;
