black stripe down the centre, generally widened at the 

 apex, often reduced in the cj to a single spot, apical margin 

 black, bidentate in the ? and ?, face above the clypeus 

 with a yellow spot in the sinus of each eye, and a trape- 

 zoidal-shaped spot between the antennce, eyes nearly 

 touching the base of the mandibles, antennte in the $ with 

 a yellow spot on the scape ; thorax black, punctured and 

 clothed like the head, sides of the pronotal emargination 

 yellow, the stripe parallel-sided, a spot on the mesopleurse 

 just below the tegulae, two spots on the scutellum, two 

 on the metanotum and two on the propodeum yellow ; 

 abdomen yellow, dull, clothed with short pale hairs, with a 

 black basal baud, angularly produced in the centre, on 

 each segment, with a round black spot on each side of the 

 angle, the black colour often extended so as to enclose the 

 spots; this latter is the normal coloration of the J', but 

 both it and the ? sometimes have the abdomen marked 

 almost as in germanica, segments beneath with a black 

 basal band and two lateral spots below it, these are often 

 united, sagittse of the S widely spoon-shaped, the apex 

 not emarginate ; legs yellow, the femoira except at the apex, 

 and the tibiae inwardly, black. 



L. (? 17 mm., ? 18-20 mm., ? 12-15 mm. 



Common everywhere. 



The parallel-sided stripes of the pronotum and the broad 

 clypeal stripe, widened at the apex, distinguish this species 

 in the $ and ? from germanica, and the form of the 

 armature distinguishes the ^. 



V, germanica, Fah. — Very like vulgaris, and in some 

 varieties very difficult to separate from it. 



(J. This sex may be known from vulgarig by the 

 shorter pubescence of its abdomen, and the very differently 

 shaped genital armature, in which the sagittas are emar- 

 ginate at the apex, instead of simply rounded ; the truncate 

 portion of the basal segment of tho abdomen is black, but 

 the dorsal surface has ouly three small black spots at the
