Head Ijkick, wiili the clypeus discreted and broadly rounded at the 

 apex ; mandibular teeth of equal length ; peristomium not very broad. 

 Antennae filiform, .slightly incrassate towards their apices ; the two basal 

 joints black and the following eight dark red. Thorax immaculate ; meta- 

 thorax hardly rugulose with the areola entire ; petiolar area coarsely rugose 

 and not discreted, spiracles circular. Scutellum black. Abdomen glabrous 

 and red, with the petiole alone, or the basal segment except its apex, 

 black ; post-|)etiole glabrous and nearly parallel-sided with no carinae ; 

 terebra nearly half the length of the abdomen. Legs black or badious ; 

 the anterior tarsi and apices of their femora, the anterior and usually base 

 of the hind tibiae, red ; tibiae not strongly spinose, the hind ones simple. 

 Wings slightly clouded, with the radix stramineous and tegulae black. 

 Length, 6 mm. 



The male is said to differ only in its white palpi and sub-rugose second 

 segment ; its abdomen is oval. 



This species is very like the last-described, of which Taschenberg 

 thought the $ no more than a variety, differing mainly in its flagellum 

 bearing no white band ; Thomson, however, says that the fifth to eleventh 

 antennal joints of the $ are white, but it appears very doubtful to me 

 whether he described the true Gravenhorstian species. He adds that it 

 may be known by the immaculate anus in both sexes and the sub-rugosely 

 punctate second $ segment. 



With this species Schmiedeknecht synonymizes both sexes of Phygadeiion 

 obsairipes, Tasch. [cf. ante p. 36, footnote). 



This species occurs on umbelliferous flowers throughout north and 

 central Europe, but has been seldom recognized in Britain. Gravenhorst 

 tells us that Hope took it at Netley, in Shropshire ; Stephens found it near 

 London, in June ; and it is recorded, upon the authority of Fitch, from 

 Maldon, in Essex. I have seen no male of this insect, but the females 

 (with no white flagellar band) have occurred to me on Umbelliferae, at 

 Felixstowe, towards the end of June, and at Huntingfield, in Kent, at 

 the beginning of August ; Chitty has captured it at Forres, in September, 

 and Marshall at Rannoch, Bishopsteignton in Devon, and Nunton in 

 Wiltshire.

(?. Head black, with the palpi elongate and white; the face and 

 cheeks with long and dense grey pubescence ; clypeus sometimes white. 

 Antennae elongate, with the flagellar joints not very distinct, the six basal 

 more or less rufescent beneath. Thorax immaculate, with long and dense
