OF NOBTHUMBEELAND AND DUBHAM. 167 



hedge-rows, often burrowing to a considerable depth. I once 

 only noticed a departure from this habit : a colony had been 

 established in the wall of a stable, probably to avoid the dis- 

 comforts of a wet season. I found it nearly as common at Tain, 

 in Kosshire. 



10. B. soroensis, Fab. Smith, Monog., 227, 14; Apis Cullu- 



manis, Kirby, Mon. Ap. Angl., II., 359, 102 $. 



The sexes of this elegant species have occurred but very rarely 

 at Gosforth; where I have also taken the Var. B. of the male 

 of Scrimshiranus of Mr. Smith's "Monograph," with " the two 

 basal segments yellow," and which he now regards as the Var. 

 collinus of soroensis. 



11. B. lapidarius, Linn. Smith, Monog., 228, 15 ; Apis lapi- 



daria, Kirby, Mon. Ap. Angl., II., 363, 106. 



The common red-tailed "Bumler" of our district. It is found 

 in plenty both inland and on the sea coast. On Whitley Links 

 it is very abundant ; and there I have seen the male and female 

 in copula on the sand at the end of August. This species was 

 also plentiful at Tain in September. 



12. B. Jiortorum, Linn. Smith, Monog., 230, 16; Apis hor- 



torum, Kirby, Mon. Ap. Angl., IL, 339, 91. 



This is a very common and generally distributed species, 

 which may be known at once by its long proboscis, and the 

 shape of its head, which is more elongate than in other species. 

 I took the sexes of this species in copula on the wing, at Long 

 Benton, on the 26th of July. 



13. B. subterr emeus, Linn. Smith, Monog., 232, 18; Apis 



Harrisella, Kirby, Mon. Ap. Angl., IL, 373, 110, t. 18, 

 fig. 7, $,8, $. 



G-ibside, Mr. J. Hardy. I have taken the female sparingly on 

 the links, near Blyth, and Whitley, in May and June.
