Copulation and Ovulation in Anabrus Simplex Hald. 



By C. P. GILLETTE. 



The so-called Mormon cricket, Anabrus simplex, appeared 

 in great numbers in portions of Routt County, Colorado, the 

 past summer. While studying the habits of this wingless 

 grasshopper, near Eddy, my attention was attracted by the 

 large white masses of a jelly-like material that were attached 

 to the abdomens of the females just beneath the ovipositors. 

 They had also been noticed by the ranchmen who spoke of 

 them as "white sacs" and "blubber." I concluded the 

 phenomenon must be associated in some way with the process 

 of fertilization and began an investigation. By pinching the 

 abdomens of several females having the white masses attached 

 I found they could be removed without breaking or tearing 

 any organ and that they were held in place by the vulva which 

 grasped a small portion or lobe. Several examples of both 

 sexes were then taken at random from the swarm and their 

 p.bdomens were opened in search of this body but it was not 

 found. I noticed, however, that the seminiferous tubules of 

 the males were filled with a milky white fluid before copula-
