172 THE HUMBLE-BEE VIII 
clothed with long greyish-yellow hairs. The hairs on the 
tibiz are greyish-yellow, not red as in derhamellus. 
The coat is denser and somewhat longer than in 
derhamellus: on the abdomen it is even, not shaggy as 
in derhamellus, and, especially on the 2nd, 3rd, and 4th 
segments, is more erect than in that species. 
The hind metatarsi are not parallel-sided as in derhamel- 
/us, but narrow gradually from below the middle to the base. 
Eyes rather prominent. Cheeks short, shorter than in 
derhamellus. 
Antenne with 3rd joint longer than 4th. Length of 
flagellum 5mm. Each joint of the flagellum except the first 
is slightly arched, more distinctly so than in derhamellus, 
and joints 6-12 are not swelled behind as in that species. 
Armature distinct. 
Very rare in Britain where only the male has so 
far been found. The type specimen was taken by 
Kirby at Witnesham in Suffolk. Four more speci- 
mens were captured at Southend, by Smith, who 
also recorded examples from Brighton Downs and 
Bristol. All these captures were made over thirty 
years ago, and none have been recorded since, but 
on September 8, 1911, I took a somewhat faded 
male at Ripple on a roadside head of Centaurea nigra. 
A colour photograph of this specimen is shown in 
Plate II. Probably, if it were sufficiently looked for, 
the species would be found existing over an exten- 
sive area in the south and east of England. It is 
also rare on the Continent. 
This is evidently a late-appearing humble-bee, 
for the Southend specimens were taken at the end of 
August and my capture was made when the other 
species were beginning to disappear.
