ABT. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 175 



BICYRTES SPINOSA (Fabricins)

This species bears some resemblance to variegrata. The discal 

 marks on the scutum, however, are distinctive, being relatively very 

 short and very broad, either oval in outline or triangular, in which 

 case the anterior end of the discal mark forms the base of the triangle. 

 The triangular lateral spots on the scutellum show a tendency to 

 elongate along the anterior border of the sclerite. The color, in 

 well-preserved specimens, is a bright orange yellow. The sixth ter- 

 gite of some females bears, on the apical part of the tergite, short, 

 weakly-developed lateral lines and the seventh tergite of the male 

 bears well defined, rounded basal lateral angles. On many of the 

 specimens that I have referred to this species, both males and 

 females, there is a consi^icuousi black spot at the base of the clypeus.

 vol. 98, 1889, p. 490.— Daixa Torre, Cat. Hym., vol. 8, 1897, p. 495. 



I have before me two females that I have referred to this species.
