OBSERVATIONS. 



The disparity of size between the sexes of 

 this species, would almost lead iis to doubt 

 their specific identity, or at least it would induce 

 us to believe that the diminutive male is no 

 other than the young of the female he accom- 

 panies as a mate. 



On a journey to Florida with Mr. JMaclure, 

 T obtained a female which was crawling up the 

 body of an Orange tree on Cumberland Island, 

 Georgia. The male I had not seen until the 

 recent return of Mr. T. Peale from that coun- 

 try, who brought many individuals of both 

 sexes. He observed them in plenty in the 

 southern part of that region. They were gene- 

 rally in pairs, on the Palmetto, lying close to 

 the rib of the leaf. Mr. Peale remarked that 

 when taken they discharged a milky fluid, from 

 two pores of the thorax, diff'using a strong odour, 

 in a great measure like that of the common 

 Gnapthalium, or " Life everlasting;" and as 

 this plant was growing near the place where 

 they occurred, he supposed that it constituted 

 at least part of their food. They vary much 

 in colour, but it is believed that the two dorsal 

 yellow stripes are never wanting.
