14S FAIVIILI^. (Jpis. *.h:) 



■A. Fahriciana, ferruginata, and cariosa, all of 

 which, I believe, belong to it, as distinct specie?. 

 All the Nomadce of Panzer, N. scutellaris and 

 cnicigera excepted, are to be referred here. 



The history, economy, and mode of nidification 

 of the insects of this family, as yet remains a se- 

 cret : they frequent warm dry banks, out of the 

 holes of which I have often seen them issue. They 

 seem to be furnished with no means of carrying 

 pollen. Their flight is silent, unattended by any 

 hum. Their eyes, when they are first taken, exhi- 

 bit a remarkable appearance, through the external 

 reticulated covering a surface of hexagons is visible, 

 which keeps shifting with the light. This appear- 

 ance is also observable in Jpis Conica, and some 

 individuals of other families.
