546 Insects, 



Sp. 4. BOMBUS SYLVARUM. 



A. sylvarum, Linn. Kirby's Mon. 



Of this beautiful species there is a specimen in the Linnean cabinet. 

 All the sexes are very similar in colour; and if captured in the autumn, 

 when the insects are recently disclosed, it is certainly one of the most 

 beautiful of all the species. It builds a moss nest in meadows. 



Sp. 5. BOMBUS ERICETORUM. 



A. ericetorum, Panzer. 



The only specimen which I have seen is in the cabinet of Mr. 

 Curtis. Panzer's figure is coloured too brown, as he describes it 

 "hirsuta flava;" Mr. Curtis's insect exactly answers to Panzer's de- 

 scription. I add a description of Mr. Curtis's specimen. Black, 

 clothed with yellow hairs, the face with white hairs : the thorax pos- 

 teriorly and the base of the scutellum, dusky : a line of ferruginous 

 hairs at the base of the second segment of the abdomen, the fourth has 

 a blackish band, and the fifth and sixth are white : the legs are cloth- 

 ed with black hairs. This insect was taken in Scotland ; it is either 

 a female or a large neuter. 



Sp. 6. BOMBUS LUCORUM. 



A. lucoriim, Linn. Kirby's Mon. 



The male of this species, named by Linneus, is in the Linnean ca- 

 binet : the female is not described in Kirby ; I have frequently ob- 

 served that which I consider to be such, in company with the male, 

 and in fact they resemble each other in general form very closely ; it 

 somewhat resembles terrestris, but the yellow bands are of a different 

 shade, more inclined to ochraceous. The bands are similarly disposed 

 both on this insect and terrestris, but the pubescence is shorter and 

 smoother, and the insect is also shorter and broader in proportion ; 

 the tip of the abdomen is white. The Bombus virginalis of Kirby ap- 

 pears to me to be the neuter of this bee. I am unacquainted with its 

 mode of nidification. 



Sp. 7. Bombus hortorum. 

 A. hortorum, Linn. Kirby's Mon. 



Of this bee there is a specimen in the Linnean cabinet; it is a fe- 

 male. This species somewhat resembles the Tunstallana of Kirby, 

 but the latter I have never seen with the bright yellow band, always
