 This is again another of those Bombinatrices, 

 which, like A. campestris and Barbutella, have no 

 instruments for carrying or preparing masses of 

 pollen. The posterior tibiae, of one specimen in 

 my cabinet, is covered from one end to the other 

 with a thin coat of pale earth, mixed with particles 

 of sand ; they probably use this in constructing 

 their nests or cells. This species \^'as known to 

 GeofFroy, who has described it with great accuracy 

 in the following terms : " Cette grande espece est 

 noire. Le haut ou la base de son corcelet a une 

 bande de poils jaunes citrons. Les deux tiers su- 

 p^rieurs du ventre sont noirs, ensuite il y a quel- 

 ques poils jaunes, et son extremite est blanche. Les 

 ailes sont brunes." He has neglected, however, to 

 notice the black extremity of the anus.
