2nd joint of the flagellum, which, in the (^, is as long as the following 

 two together, and in the ? is as long as the next three. Whereas, in 

 Gwynana the 2nd joint in the $ is only a little longer than the 3rd, 

 and in the % the 2nd is distinctly shorter than the next three. The 

 distance between the eye and the mandible is also longer in Gwynana^ 

 ? , than in the present species, and more shining. In colour this 

 species resembles very pale Gwynana, the hairs of the face being 

 greyish-brow^n, and the margins of the segments of the abdomen 

 fringed with pale hairs. I find specimens in my collection agreeing 

 with those sent by Mr. Perkins, from Wandsworth, ? , and Chobham, 

 $ and ? , and I took two females this year at Bromley, in June. Mr. 

 Perkins' specimens w^ere captured on Allium ursinum, which he says 

 is its usual plant. 



4. BOMBUS NIVALIS, Dhlb. ?. 



Through the kindness of Mr. C. A. Briggs, I have been able toj 

 obtain from Unst, Shetland, a $ , w^hich agrees exactly with the sjDCci- 

 men of that sex in the British Museum; the ^, however, is still 

 wanted to decide for certain if the species found in Shetland be 

 identical with nivalis, Dahlb.
