This is one of our native worms possess-iiig many charac ers which closely ally it tothe Cynthia worm. Its cocoon is, like thrtofthe two preceding species, elongate and openat one end. It is also double, but tlie outercoat is not loose and rough, but smooth andsolid like a jiiece of tough nianilla paper; andthere is very little space, and consequentlyvery little floss silk between it and the innercoat. The silk is finer, weaker, less in quan-tity, and much more closely compacted andagglutinated than in the others, and, whencoupled with the fact that it is suspended by arope or cord, as long as, and often longer than, lessIopia orCynthia worms.
