vil BOMBUS CULLUMANUS 17 
8. BOMBUS CULLUMANUS, Kirby. 
Cullum’s Humble-bee. 
QUEEN and WORKER.—The queen and worker of 
this species have not yet been taken in Britain. 
Their size is probably medium. 
Specimens of large workers in the Saunders’ collection 
from Burgos, Spain, are black with a greyish-yellow band 
on the front of the thorax and a somewhat narrower one 
at the back; the Ist and 2nd segments of the abdomen 
greyish-yellow, and the 4th and following segments red. 
In specimens in the same collection from Schleswig, the 
4th and following segments are red, but the greyish-yellow 
bands are absent. 
In all the specimens the corbicula hairs are black, but 
the longer ones are tinged with yellow. The fluff on the 
limen is paler than in /apzdarzus. 
The coat is rather short, even and stiff. The hairs on 
the legs are rather shorter and stiffer than in most species. 
Cheeks slightly shorter than in J/apzdarzus, and more 
strongly punctured at the sides and base. 
I find that, under the microscope, the hind metatarsi 
are not covered with a net-like pattern as in /apzdarzus, 
derhamellus, and (the base excepted) pratorum. Upper 
apical corner of hind tibie much upturned. Auricle not 
hairy on the inner side as in /apzdarius. Length of 
3rd antennal joint about 13 times its apical width; in 
lapidarius and derhamellus it is about twice its apical 
width. 
MALE.—Length 13-144 mm., expanse 26-28 mm. 
The colouring is very like that of an extremely light 
derhamellus male. 
Face and top of the head greyish-yellow. Thorax black, 
with a greyish-yellow band in front and an almost equally wide 
one of the same colour posteriorly, Abdomen with the Ist 
and 2nd segments greyish-yellow, 3rd segment black, the 
division between the black and the yellow very clearly 
defined, 4th and following segments red. The underside is
