net, with the authentic label attached. The species varies, but not 

 very commonly. Sometimes the yellow collar nearly or quite disap- 

 pears, and the tip of the abdomen is sometimes whitish ; it therefore 

 approaches B. Soroensis in its varieties, but may be always known by 

 the differently shaped head, which is much rounder and broader than 

 in B. Soroensis. The male is figured in Panzer under the name of 

 Bremus collaris : it is similar to the female in colour, as is also the 

 neuter ; the latter varies considerably in size, from 4j to 7 lines. It 

 builds its nest underground, also under stones and rubbish. 



Sp. 11. BOMBUS PRATORUM. 



A. subinterniptus, Kirby's Mon. 



A long series of varieties, containing specimens quite as apparently 

 distinct as those separated by Mr. Kirby, convince me that the fol- 

 lowing constitute but one species. Apis Donovanella, Kirby, female, 

 A. arbustorum, Fabr., fem., of which there is a specimen in the Bank- 

 sian cabinet. The A. pratorum of Kirby and of Linnaeus appears 

 on comparison with the authentic specimen in the Linnean museum 

 to be the neuter. The male is the A. Burrellana and A. Cullumana 

 of Kirby ; the latter variety is rare, out of all the males I ever captured 

 I have only met with one specimen ; there are two in the Kirbyan ca- 

 binet : it differs from the generality of males in the same manner as 

 the A. Donovanella does from the rest of the females, in the yellow 

 bands being pale tawny instead of the usual bright yellow, and the 

 anal red band is wider. 



Sp. 12. Bombus colltnus, new species. 



This species was taken first by Mr. A. Griesbach, near Westow, 

 Yorkshire, and subsequently by Mr. W. H. L. Walcott, in the neigh- 

 bourhood of Bristol ; Mr. Walcott has also received it from Brighton, 

 captured on the Downs. I am indebted to this gentleman for a spe- 

 cimen, which is a male; the female is at present unknown. The male 

 resembles in general appearance the male of subinterruptus, the Apis 

 Burrellana of Kirby ; but it has a black face, and a white tip to the 

 abdomen. 



Bombus collinus, male. — Head and thorax black, the latter with a 

 yellow band on the collar, which unites with hairs of the same colour 

 that clothe the thorax beneath. The abdomen has a yellow band at 

 the base, which occupies two segments ; the third has a black band, 

 the fourth a narrow line of fulvous hairs, and the remaining segments 

 are clothed with white hairs. (Size, 5 J lines).
