When picked up by the fingers, there is exuded from glands on the 

 sides of the thorax a vapor from the male and a white milky fluid 

 from the female. This possesses a peculiar, though somewhat pleas- 

 ing odor, which has been likened to that of the common Everlasting,

 perhaps harmful, to birds and rapacious insects. Scudder (Psyche I) 

 has noted this secretion, and concludes that the PhasmidcB with their 

 slender form and sluggish movements have especial need of such a 

 weapon as these glands furnish. 



None of the specimens of ferruginea noted were feeding, though 

 they probably live upon the leaves of oak and other trees. The spe- 

 cies was later found in numbers in Posey County, and probably occurs 

 in most of the counties bordering the Ohio Eiver. It is but one of 

 many forms of insect and plant life which have their most northern 

 habitat in the southern third of Indiana. Specimens in the U. S. 

 National Museum are from Florida, Louisiana, Kentucky and Penn- 

 sylvania.*
