76 THE BIOLOGICAL REVIEW. 



October 8. 9 A, began to excavate a burrow; she pushed 

 "the end of her abdomen in and, while standing nearly erect, 

 used her hind feet as scrapers, always scraping forwards and 

 bringing the scrapings up in front and on both sides, and it was 

 very interesting to see how well her ungainly-looking limbs 

 were fitted for the purpose. 



October 10. Burrow finished deep enough to receive her 

 abdomen up to the thorax, and she began ovapositing ; while 

 doing so she remained quite still, except slight movements of 

 the fore legs and antennae. 



October n. 9 A, came out of the burrow after having 

 ovaposited thirty hours. She very carefully covered the ova, 

 and levelled up the hole nicely and began to feed on R. acris, 

 looking somewhat flabby. 



9 B, has finished digging her first hole and is now ova- 

 positing. 



October 12. 9 B, came out of her burrow, having been 

 •ovapositing twenty-six hours. In covering up her ova she used 

 both fore and hind feet. She at once commenced feeding on 

 R. acris. 



October 14. 9 A, in coitu with cT A ; apart in the evening. 



October 15. 9 B, in coitu with c? A ; parted in the 

 afternoon. 



October 17. 9 A, excavating another burrow; began 

 ovapositing in afternoon. 



October 18. 9 A, came out of burrow after ovapositing 

 twelve hours ; feebly covered up her ova ; she is exceedingly 

 emaciated. 9 B, has made a second burrow, and is ovapositing. 



October 20. 9 A, in coitu with c? B. 9 B, came out of 

 burrow, having ovaposited seventeen hours. Both 9 s are 

 feeding sparingly on R. acris. 



October 26. 9 A, ovapositing above ground, not being able 

 to burrow ; she is very feeble. 



October 27. 9 A, lying dead above her ova. 9 B, is 

 ovapositing in a very shallow burrow. She was not able to 

 •cover her ova, although she tried several minutes ; she is 

 scarcely able to crawl. 



October 29. 9 B, slowly crawling over leaves of R. acris, 

 but unable to eat.
