[Wherever mud was found these insects were seen 
collecting it for making their nests. 
Both this species and the preceding, which is idistin- 
guishable from it on the wing, present a very peculiar 
appearance during flight. The pale yellow parts of body 
and legs become invisible, while the black areas are ex- 
tremely conspicuous. The limbs are probably so held 
during the flight of the imsect that their yellow sections 
come beneath the median yellow of the body. However 
this may be the terminal black parts seem to be completely 
detached, suggesting the appearance of two insects, one 
pursuing the other, or a predaceous species carrying its 
prey. &. B: P.]
