that the larva matures in 11 to 13 days, the pupa in 2 days and 

 the adult issues from 14 to 16 days later. This gives 27 to 31 

 days from the egg to adult. There are two generations each 

 year, the second hibernating. 



He also records a species of Eulophus the adults of which 

 appear about the middle to the end of May. The eggs, from 

 one to six in number, are deposited on the outside of the body 

 of the Phytonomus larva. This parasite may also be hyper- 

 parasitic on Canidia. 



A third parasite recorded is Pimpla maculator F., the life- 

 history of which is unknown. 



Three hyperparasites are recorded: a Habrocytus, a Chalcid 

 and Dibrachis boucheanus, all living upon the Canidia. 



Disease: Attempts were made in 1910 by the agents of the 

 Bureau of Entomology to introduce Entomophthora sphaeros- 

 perma into Utah. It is not yet certain that these were successful 

 and even if introduced it is extermely improbable that the dis- 

 ease will be of any particular value in the arid regions of the 

 West.
