The Hopvine Plusia. 



( Plusia hulhica. — (leyer. ) 



Order, Lepidoptera ; Family, Noctuid.e. 



[The measurements of insects in this work are given in inches and lines. The above cut rep- 

 resents one inch divided into lines and fractions thereof. ] 



[Feeding upon the leaves of the hopvine ; a green, fourteen- 

 legged caterpiUar, marked with white streaks ; the head green, 

 and destitute of black dots.] 



This caterpillar arches up its back slightly when crawling. 

 When fully grown it measures about one inch and three lines 

 in length. It then crawls into some sheltered place and sjiins 

 a thin cocoon. The fore-wings of the perfect moth expand 

 about one inch and nine lines ; they are almost entirely cov- 

 ered with metallic green scales, and are crossed by two oblique 

 dark lines. The hind wings are dusky gray. 



I have not found this species in this State. The above 

 account is taken from the Canadian Entomological Report 

 for 1873.
