Auguft, and defcend into the ground, late in September or the firfl: 

 V/eek in 06lober, and the Fly comes forth in July. 



Caterpillars that enter the earth in the larva form, pafs to the 

 chryfalis, and ifiue forth in the perfe6l or Fly (rate, have no occafion 

 for a web to protect them ; and therefore few fpecies prepare one. But 

 among thofe which remain expofed in the open air, a very fmall pro- 

 portion neglect to weave a web with the utmoft fkill and induftry ; the 

 leaft attentive to this apparently neceffary precaution are the Papiliones, 

 who, often regardlefs of their fituations, are found [in chryfalis] fuf- 

 pended -againft walls, the trunks, or branches of trees, and even 

 paleings in very public roads.
