SPHERULARIA BOMBI IN AMERICA. 



An animal in wliich Prolapsus vaginae is normal. 



By Ch. Wardell Stiles, Ph. D. 



Prof. John B, Smith recently sent me some parasites {Spheru- 

 laria bombi) from the body-cavity of the Humble-Bee for deter- 

 mination and requested me to write a short account of them for 

 publication in Entomological News.* I acceed to the request 

 all the more willingly as, so far as I have been able to find, this 

 curious parasite has never been described in American literature, 

 although several records of the presence of a parasite in the Hum- 

 ble Bee occur in American journals which undoubtedly refer to this 

 particular species. 



The parasite in question is one of those curious forms in which, 

 what frequently occurs to a moderate degree as a pathological 

 process in higher animals, here takes place to an enormous ex- 

 tent as the normal condition of affairs; it is further an extremely 

 interesting form, as a particular set of organs normally undergoes 

 an hypertrophy entirely out of proportion to its original size, or 

 in fact to the size of the original organism. A third point in 

 connection with the worm is that it represents one of those pecu- 

 liar cases of parasitism in which only the female sex lives a para- 

 sitic life. 



* I found specimens in miterial collected by my students in female Boinbus pennsylva- 

 nicus, B. fervidus and B. consimilis.
