 curved in some, reflexcd in others, shorter than the 

 sheathing tube. Palpi alike.

 Ans. Linnaeus, Olivier, Villers. 

 Andrena. Fabricius, Jurine. 

 IlYLiEL's. Cuvier. 

 Evodia. Panzer. 

 Melitta. * a. Kirby. 



Hinder feet pollenigerous. Superior wings with three 

 submarginal cells. Antennae with the third joint longer 

 than the second. Abdomen much elongated, more or 

 less villose. Ocelli forming a curved line. Tongue 

 obtuse, the apex bilobate. 



The shape of the tongue is admirably adapted for the 

 construction of its cells, which are described by the accu- 

 rate Reaumur in the fifth memoir of his sixth volume, 

 " dont les nids sontfaits d'esfieces de vicmbranes soyeuses." 

 According to this author, they make their nests in the 

 earth that fills the cavities of certain stone walls. Some 

 of them choose a northern aspect sheltered by trees. 

 These nests are cylindrical, and consist of from two to 

 four cells placed end to end, each of which is formed 

 like a thimble, the end of one fitting into the other. The 

 cells vary in size. The cylinder runs in a horizontal di- 

 rection; but sometimes, from the intervention of a stone 

 or of some other obstacle, it takes a different course, so 

 that the last cell forms an angle with the first. The 

 cells are composed of many layers of a very thin and 

 transparent membrane, and the colour is generally red- 

 dish brown, which arises from the substance with which 

 they are constructed. This is sometimes nearly liquid, 

 at others it is meiely a paste composed of pollen and 

 honey. The larva, when hatched, very soon imbibes all 

 that is liquid, and when full grown quite fills its cell. 

 The substance with which they form their cells has not 

 been ascertained, but Reaumur conjectures it to be a 

 secretion from the insect.
