In no case has the breeding of any blood-sucking 

 Life-history. Muscid (other than Glossina) yet been observed 



in Africa, but the metamorphoses of species of 



Stomoxys and Lyperosia have been studied in Europe and the United 



States,! while those of Philcematomyia insignis have been investigated 



in India by Mr. F. M. Howlett. All of these flies breed as a rule in 



the fresh droppings of Ungulates, though Stomoxys calcitrans was 



also noticed by Newstead ovipositing in cut and heated grass. The 



larvae are footless whitish or yellowish maggots, of the type of those 



of Musca domestica or Calliphora erythrocephala, Mg. (the common 



Blow-fly). Pupation takes place in the ground beneath the dung, 



and the puparium or pupa-case, which is barrel-shaped or ellipsoidal, 



slightly narrower in front, varies in colour from red to dark brown.
