tion, and that after copulation they were empty and yellow in 

 color. A male and female in copula were then separated, just 

 before the close of the process and before the sperm mass had 

 made its appearance. The male abdomen was then pinched 

 so as to crowd the contents towards the end, and a sperm 

 mass, exactly like those taken from females, was obtained. 

 I therefore concluded that during copulation the males fill 

 these sacs with seminal fluid and then transfer them bodily to 

 the females who seize them by two of the small lobes, Fig. i 

 C and D. The females carry these conspicuous white objects 

 about for a time, extracting a portion, at least, of their con- 

 tents for the fertilization of the ova. 



It was noticed that the females bearing these seminal sacs 

 were most numerous about 9 or 10 o'clock in the morning, and 

 that few or none could be found after i or 2 in the afternoon. 



Mr. W. W. Miles, postmaster at Eddy, told me he and Mrs. 

 Miles noticed these white sacs attached to the females in great 

 numbers on their ranch during the forenoon of June 27th. 

 Mr. Miles also noticed the females depositing eggs July 5th. 



While passing through a large swarm of the hoppers at 9 

 o'clock in the morning of July 79th, it was noticed that fully 

 half of the females were carr5ang about these sacs, and the 

 males everywhere were noisy with their stridulations. Whether 

 copulation takes place more than once during the egg-laying 

 period of a female, I have been unable to determine with 

 certaint3\ 



Numerous females bearing the sperm sacs were dissected 

 and in all cases there were many eggs present in the ovaries, 

 some with dark firm shells, apparently ready to be deposited, 

 and others soft and yellow and in all stages of maturity from 

 those less than half-grown to those of full size. 



There was no indication that the eggs were developing in 

 sets or broods, for they seemed to grade through all stages 

 from those that were small and just developing to those fully 

 mature. Counts made at Eddy on July 27th gave from 10 to 

 35 apparently mature eggs, and from 34 to 46 immature eggs 

 in ovaries of single females taken with the sperm sacs 

 attached.
