5 In the first volume of my Monographia Apam Anglice (p. -209) I gave the characters of a tribe of humble-bees which 

 differ so much in their characters as to indicate an important difference in their economy, and to entitle them to the rank 

 of a genus. Their labrum is obtusangular ; their mandibles obliquely truncated; their posterior tibia 1 and plantae are with- 

 out any apparatus for carrying and kneading the pollen ; their abdomen is inflexed and the last ventral segment projects on 

 each side so as to form an angle ; all characters not to be found in the other Bombi, no writer seems to have noticed this 

 tribe, unless King's Ptilopus be synonymous with it, which I have not the means of ascertaining, if not already named I 

 would call the genus by Jurine's name Bremus. Apis campestris, Barbutetla, vestalis and rvpcstris, Mon. Api. Angl. belong 

 to it.
