This insect is at times quite common in southern Illinois, and as I 

 am informed by Prof. French, has noticeably decreased the members 

 of the handsome butterfly upon which it preys. The cocoons are 

 yellow, 5 mm. long by 2.2 mm. in diameter. They are spun singly 

 upon grass blades or similar materials, and have little loose silk,

A specimen from New Jersey resembles this species very much, 

 but differs so in its darker color, reticulate scutellum, etc., that I 

 prefer to leave it for the present without referring it to this species 

 or describing it as distinct.
