ScELlPHRON SPIRIFEX, L. Common. 



[Wherever mud was foimd these insects were seen 

 collecting it for making their nests. 



Both this species and the preceding, which is indistin- 

 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 insect that their yellow sections 

 come beneath the median yelloAv 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. E. B. P.]
