no. 2173. A REVISION OF THE BE MB WINE WASPS— PARKER. HI 



The pubescence is relatively short, white, and moderately dense, 

 more in evidence on the male than on the female. The flagellum is 

 black with a shade of reddish below on the more apical segments. On 

 the female the scape is black. The frons just above the insertion of 

 the antennae is about equal to the width of the eye at the same level. 

 The eyes diverge at the vertex and also a trifle at the clypeus. The 

 wings of the male are slightly but distinctly infumated medially; 

 those of the female are heavily infumated, resembling those of 

 nubilipennis Cresson in this respect. 



Length. — 19-22 mm. 



One of the males has only a vestige of the process on the second 

 sternite. The sixth tergite of one male has a complete fascia; on the 

 type it has only a pair of yellow spots and on a third it is entirely 

 devoid of yellow. On one female the clypeus, antennae, and frons, 

 except the spot between the antennae and the three small spots in 

 front of the anterior ocellus, are entirely black. A single female 

 from Arizona has been placed in this species. It has the narrow 

 frons and infumated wings, but the black on the clypeus has been 

 reduced to two small basal spots and the scape is broadly yellow below. 



This species stands close to nubilipennis Cresson from which it can 

 readily be distinguished in the male by the nonspinose antennae and 

 the simple middle femora. The female differs from Cresson's species 

 by the presence of the black on the clypeus and by the much narrower 

 frons, which in nubilipennis is much wider than the eye at the point 

 just above the insertion of the antennae. Described from three 

 males and four females. 



Habitat. — California, Arizona.
