ABT. 5 GENERIC REVISION OF THE FOSSOEIAL WASPS PARKER IQU 



broad and is slightly emarginate at the apex, also beai-s a median 

 well-developed process, such as is usually found on the sixth in other 

 species. The eighth terminates in a comparatively broad, flattened, 

 bluntly-pointed spine, differing thus from most species in which 

 the eighth terminates in a rounded acutely-pointed spine. The sev- 

 enth tergite is abruptly narrowed and rather sharply-pointed 

 apically (fig. 139). 



Allotype. — The female so closely resembles the male in color and 

 markings as to render a separate description unnecessary. On the 

 dorsal areas and the sides the maculations are somewhat better 

 developed than on the male, but on the sternites they are more 

 reduced. The black on the legs is more extensive, lines being present 

 cm the posterior surfaces of all tibiae and femora and on the anterior 

 surface of the posterior femora. 



The wings in this species are hyaline and the pubescence normal. 

 The color of the maculations as seen on the specimens is a soiled 

 muddy yellow, but I am certain that these specimens have been 

 damaged so that they do not represent the true color of the living 

 insect. 



Length 20 mm. Described from one male and one female from

This species is closely related to Bemhix nuhilipennis Cresson. 

 Like that species, it has the middle femora irregularly dentate, seg- 

 ments 7 and 8 of the flagellum prominently spinose, and sternite 6 

 with small, though evident, lateral processes in addition to the 

 median process. It differs from nubUipennis in the form of the 

 genital stipes and in the character of the maculations. On this 

 species the thorax and propodeum are entirely black, while on 

 'nubilipennis the prothorax is more or less profusely marked with 

 yellow. The pubescence is much more conspicuous than on 

 nuhilipennis. 



This species Avas described from males taken at San Miguel Island^
