female; in botli sexes the two narrow black lines on abdonien, the 

 absence of long hairs on the middle tibiæ, and, as a rule. tlie veinlet 

 from the anterior branch of the cubital foi-i<. 



T. rusticus is a rather frequent species here, and sometimes it 

 occurs in great numbers, but I have hitherto not seen it from Jutland. 

 It seems to be a species which is more attracted by flowers than is 

 commonly the case, and it is often seen on Umbelliferæ; vicinity of 

 Copenhagen, Damhusmosen, Ordrup Mose, Hillerød, Frerslev Hegn, 

 Grib Skov and Esromsø, in the latter place in very great numbers 

 on Sonchus in the last half of July; Funen at Odense and on Born- 

 iiolm at Hasle and Rønne. It seems to be a species occuring some- 

 what late, my records date from ■^h — v'r; Zetterstedt 1. c. refers that 

 iie has seen it to the ' ii. 



Geographical distribution: — All Europe; it seems to have its 

 northern limit in southem Scandinavia.

Of this species I have only seen the female, as to the male I 

 quote the following from Brauer. Eyes densely and long, pale hairy; 

 eye-facets of difierent sizes about as in rusticus; as a rule there is 

 no band on the eye. Antennæ reddish yellow; the angle of the third 

 joint near to the base, style somewhat sliorter than the third joint, 

 apical joint conical. Palpi with the second joint long elliptical, some- 

 what more ovate than in rusticus (Brauer's figure). Thorax densely 

 covered with yellowish golden hairs. Abdomen much as in rusticus, 

 the reddish markings, however, are more extended, and the pubescence 

 more golden yellow. Legs mainly reddish yellow; coxæ and base of 

 femora more or less blackish ; tips of the front tibiæ, front tarsi 

 entirely, and posterior tarsi towards the ends brownish. Femora with 

 long hairs at the base, the remainder of the legs with depressed yellow 

 silky hairs, intermingled with short black hairs on the tibiæ. Wings 

 quite as in rusticus; balteres yellow. 



Female. Eyes pale green with some nearly black, round spots, 

 and a narrow dark band ; more or less densely, short and sometimes 

 indistinctly haired. Frontal band and triangle yellow. Palpi with 

 the second joint long, somewhat thickened at the basal half, with 

 pale and black hairs. Venter generally reddish; tirst segment grey,
