luteous; in both sexes the hind femora and tibie have a broad, 
blackish ring, and the hind tarsi are blackish at the base and tip. 
It is very common in meadows. 
7. scambus, Zetterstedt, is clearly allied to the last, but the male has a 
row of about six very long solitary black hairs behind the front 
femora, and a few rather long black hairs beneath the middle 
femora near the base, the anterior femora are almost all luteous, 
the hind legs are blacker, the abdominal spots, especially the first 
pair, are rather larger, and the epistoma has more yellow hairs. I 
captured it rather commonly at Rannoch last June. 
8. angustatus, Zetterstedt : this is also very closely allied to clypeatus, 
but is smaller, the abdomen is much narrower, the abdominal spots 
are larger, the second pair being nearly twice as long as the third 
pair, while in clypeatus they are almost equal, the pubescence on 
the thorax is less abundant. I have a specimen of this captured 
near Lewes last June, and another at Darenth in May, 1868, which 
I had previously confounded with clypeatus. 
9. podagratus, Zetterstedt : also closely allied to clypeatus, but the ab- 
dominal markings are more obscure, the size is smaller, the front 
tibie are much more dilated at the tip, the anterior femora are 
more blackish, and the hind legs are all shining black, except just 
the knees. I captured a few specimens of this at Ranuoch last 
June. 
10. immarginatus, Zetterstedt: this and fulviventris are distinguished 
from the four preceding by the much greater extension of the pale 
markings of the abdomen, so that Walker quite correctly says 
* abdomine fulvo, linea dorsali media fasciisque angustissimis nigris :” 
immarginatus has the front femora with about six long solitary 
black hairs behind (like scambus), and also has the hind femora 
and tibie with with broad black rings, and is a small species ; I 
once found it in tolerable abundance on the banks of the Thames, 
between Kew and Richmond, in August, 1868, but, mistaking it at 
the time for elypeatus, only took a few, and I have never been there 
at the right time since. I expect Walker’s ferrugineus var. b 
includes this. 
11. fulviventris, Macquart: Walker says of this species—“ Rare, in 
the collection of Entomological Club ;’’ there are two specimens 
there which I believe belong to this species, but I have never eri- 
tically examined them; I have never met with the species, but see
