FIG. i. Developmental stages of Slempellia magna observed in the host larva; 

 fed on infected material, a, c-e, X 1000; others, X 2300. a, fresh spores taken 

 from the mid-gut of a larva six hours after feeding on the infected material, b, a 

 stained spore observed in the same host individual (Giemsa). c, a fresh spore 

 observed in the contents of the mid-gut of a larva 24 hours after feeding on the 

 infected material, d. a spore found in the mid-gut contents of a larva, 40 hours 

 after feeding on the infected material, e, a spore found in the same larva (empty 

 spore membrane and the sporoplasm?). /, an empty spore and a unimicleated 

 sporoplasm (?) from the mid-gut of a larva, 24 hours after feeding on the infected 

 material (section; Heidenhain). g, two liberated sporoplasms (?) in the lumen of 

 mid-gut of the same larva (Ilcidcnhain). //, two young schizonts observed in the 

 periintestinal fat body, 24 hours after feeding. i. j, k, schizonts in various stages of 

 development and division as found in the fat-body surrounding the posterior part 

 of the mid-gut and tracheae in the larvae examined 24 hours to four days a 

 feeding on the infected material (sections; Heidenhain). /, five si-lii/mits in the 

 pcritracheal adipose tissue near the mid-gut of a larva. 48 hours after ir.-rling on the
