The Caterpillars of both forts are very general feeders; they will 

 eat oak, fruit trees, and. wild plants of almoft every kind. They 

 are common in the fummer, change to chryfalis about Auguft, and 

 appear in the winged ftate in May and June ; but, there is more 

 than one brood of them in the courfe of the year, fo that the time 

 ot their appearance is uncertain. The Caterpillars change their 

 ileins dften ; and change their colours at the fame time. Thofe of 

 Phalasna Menthraftri when fmall are a very bright tranfparent brown : 

 then brown with dark ftripes. It is not black till it appears in the 

 laft flcin ; and then, in many, the colour inclines to brown.
