BOMB US CULLUMANUS 171 



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 1st 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 lapidarius. 



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 lapidarius, 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 lapidarius, 

 derhamellus, and (the base excepted) pratorum. Upper 

 apical corner of hind tibiae much upturned. Auricle not 

 hairy on the inner side as in lapidarius. Length of 

 3rd antennal joint about \\ times its apical width; in 

 lapidarius and derJiamellus it is about twice its apical 

 width. 



MALE. Length 1 3- 14J 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 1st 

 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
