7. Burenella dimorpha may be locally abundant, even 

 though it is not common in the S. geminata population as 

 a whole. 



8. Spore dimorphism is temperature dependent. Mem- 

 brane bound sporulation is inhibited by both low (20-22.5 C) 

 and high (32 C) -temperatures; NMB sporulation is affected 

 little, if at all. 



9. Nonmembrane bound spores do not develop in lieu 

 of MB spores in the fat body at low or high temperatures. 



10. The pathognomonic signs of B. dimorpha infection 

 are due to destruction or inhibition of formation of the 

 adult cuticle. 



11. Meronts are diplocaryotic and bidiplocaryotic , 

 not uninucleate and binucleate as originally described. 



12. The NMB spore surface is smooth, but the MB spore 

 surface has a complex pattern of ridges and a well defined 

 polar cap area. 



13. The pansporoblast membrane is extremely delicate 

 and subpersistent in workers (as originally described) , 

 and in male pupae; in female pupae it is persistent.
