ABUiVDANCE OF FLEAS, 



To get some idea of the nnnd^er of fleas in the soil of an 

 infested henhouse, half a ]iint of the dry dirt from the floor 

 was placed in a glass jar and the fleas were removed as fast 

 as they emerged. The experiment was conclndeu;l at the endv 

 of about three weeks, with a total of 1.027. !

RESISTANCE OF THE NEWLY-EMERGED FLEAS. j 



In order to determine how long the fleas can live in the; 

 dry soil, without a host, they were placed in open glass jars,' 

 after emerging, and left until they died. It was found that' 

 most of them lived for over a week, and many of them much; 

 longer, some continuing for 30 days. | 



In no case were eggs produced by the fleas before feedingj 

 upon blood. It is also interesting to note that though the; 

 females are very resistant before finding a host, they quicklyt 

 succumb if removed after they have once fed upon blood, i 

 dying within a day or two. The males, on the other hand, 

 are not disturbed by removal from the host, and actually live 

 longer than they do while actively mating.

[Presented at November Meeting.] 



At a previous meeting I reported finding a tiny roach in 

 the sphagnum moss which was used for packing the large 

 i-oaches (Rliypaiohifi madprae), which Bro. Matthias Xew^ll 

 sent from Hilo, Hawaii, on Xovember 14, 1914. 



This adult specimen resendfled so closely the novv-born 

 young of the large species that I did not discover the differ-
