as November 8th, in this cold climate, after a snow of several 

 inches had fallen. They no doubt hybernate in such situations. 

 Common; more than a hundred specimens examined during 

 1891-92. 



Orono, Me. F. L. Harvey. 



Associated with P. inarm oratus on agarics and boleti; under 

 bark with the above and Smynthnrus 6-maculaa Harvey; under 

 rubbish with a large yellow Smynthurus n. sp. and half a dozen 

 other Thysanourans. 



Sluggish, slow-moving, but when disturbed can jump fully 

 eight inches. The form, long legs, clumsy movements, and 

 motion of the antennae while walking, combine to give it a gro- 

 tesque appearance. 



Relationship. Nearly the color of P. fuscus Lubbock, but 

 differs in the form of the body, smaller terminal abdominal seg- 

 ments, structure of the antennae, and much greater size. 



Most like Smynthurus novteboracensis Fitch of the described 

 American species. Agrees with it nearly in size and habitat, but 

 differs in color, somewhat greater size, and structure of the an- 

 tennae. Specimens from the Nathan Banks collection, kindly sent 

 us by Mr. Macgillevroy, have apparently but two joints beyond 

 the elbow, and the third joint though, knotty at the end, seems 

 to be entire. The form and color also seem different. 



Critical remarks. Lubbock, in his diagnosis of the genus 

 Papirhis, says there are only four joints to the antennae. The 

 figure of P. fuscus, given in his monograph, shows five (three 

 beyond the elbow). Fitch overlooked the short basal joint in 

 describing his 5". novezboracensis, and regarded the portion be- 

 yond the elbow obscurely three-jointed. Packard, in his Essex 

 Co. Catalogue, in describing P. marmoratus, first speaks of the 

 third joint being broken into short segments. Lubbock says the 

 third joint of P. fuscus appears knotty. The species we are con- 

 sidering has only the terminal half of the so-called third joint 

 broken into short segments. It appears that there is great varia- 

 bility in the third joint from entire knotty forms, though others 

 with the terminal half subjointed, to those with the entire joint 

 broken into subjoints. If we did not know one form in structure 

 stands between P. fuscus and P. miirmoratns in the structure of 

 the third antennal joint we would be compelled to regard the an
