Female. Length 5 lines. Black, punctured and shining ; the 

 clypeus very convex, and excavated in front ; the base of the 

 mandibles, the clypeus, a large semicircular spot on each side 

 of the face, and a minute spot behind the eyes, yellow ; the 

 flagellum above fuscous or black, fulvous beneath, the apical 

 joint entirely so. Thorax : a spot on each side of the collar, 

 the tegulae, and the post-scutellum, yellow ; the legs flavo- 

 ferruginous, with the coxa3, trochanters, and base of the an- 

 terior and intermediate femora, black, or frequently dark rufo- 

 piceous ; sometimes the extreme base of the posterior femora 

 stained; wings fulvo-hyaline, slightly fuscous at their apex. 

 Abdomen : a transverse spot on each side of the first segment, 

 and an attenuated band on the four following, sometimes in- 

 terrupted; the two central carinse on the apical segment widest 

 apart at the base, the space between them opake. 



The Male of this species so strongly resembles that of the pre- 

 ceding, that it is only necessary to point out the distinctions : 

 in this species the antenna? are proportjonably shorter, the 

 apical joint, although bent, is thicker, and the angles of the 

 penultimate abdominal segment are much less strongly den- 

 tate, and the pencil of hairs at their apex shorter ; the anterior 

 margin of the clypeus is not toothed ; it is also smaller, 

 varying from 3J to 4-J lines in length ; the apical segment is 

 naked in this species, whilst in C. Idbiata it is sprinkled with 

 hairs. 



This is a very local species : it occurs at Southern! ; at Birch 

 Wood, Kent, and also at Lowestoft, Suffolk; it is usually 

 found about the beginning of August ; it delights in frequent- 

 ing the flowers of the wild Parsnip. This is certainly the 

 o-fasciata of Van der Linden, as M. Wesmael has verified by an 

 examination of the typical specimens.
