206 APIDJ3. 



Var. y. The thorax fringed with yellow pubescence, that on the two 



basal segments of the abdomen yellow. 

 Tar. c. The abdomen entirely covered with obscure flavo-fuscous 



pubescence. 

 Yar. e. The abdomen almost entirely fulvous. 



The description of the male is that of the normal condition. The 

 male of Kirby's-4. donovanella is certainly that of B. derhamellus, as 

 will be seen by an examination of his typical specimen. The species 

 is generally distributed. I have frequently found its nests in hay- 

 fields ; several occurred in a hay-field at Beaumaris, in Anglesey. 

 The species is common. The bees make no defence when their nests 

 are disturbed. 



9. Bomhus pomorum. 



B. hirsutus, ater, thorace antice scutelloque obscure fiavis, abdomine 

 rufo-fulvo. 



Bomhus pomorum, Schenck, Kass. Bien. 512(5 5 $ . 



Smith, Entomol. iii. 281 2 d- 

 Bremus pomorum, Panz. Faun. Germ. 86. 18 J. 



Female. Length 8 lines. — Black ; head elongate, the clypeus smooth 

 and shining, the pubescence black. Thorax — the pubescence black, 

 in front and on the scutellum intermixed with obscurely yellow or 

 pale hairs ; the legs with black pubescence ; the basal joint of the 

 tarsi with short ferruginous pubescence beneath ; wings hyaline, 

 faintly clouded at their apical margins. Abdomen clothed with 

 rufo-fulvous pubescence, palest towards the apex and darkest on 

 the basal segment. 



Male. Length 5-6 lines. — Head elongate, the pubescence black. 

 The thorax has in front and also on the scutellum a mixture of 

 greyish hairs, that on the disk black ; the legs fringed beneath with 

 fulvous pubescence ; wings as in the female. Abdomen with fulvous 

 pubescence, that on the basal segment grey ; on the second segment 

 the colour is darker and less bright than on the rest of the abdomen. 



Var. j3. The thorax with grey pubescence, with a black band beneath 

 the wings. 



The worker I have not seen, but Schenck says it resembles the 

 female ; he also observes that the male resembles a male Apathus. 

 This is true ; but the only male of that genus it resembles is that of 

 A. rupestris, from which it is very distinct ; its elongate head and 

 naked clypeus at once distinguish '.o from that insect ; its antennae 

 are longer and more slender. B. pomorum is the rarest species found 

 in this country. I took three males in 1863, and my son a female in 

 the following year, near Deal. 



Panzer describes the basal segment of the abdomen as having 

 white hair in the male, but in the figure it is coloured black.
