68 ENTOMOLOGICAL NEWS. [February, 



tennse as broken into five well-defined regions. Are the species 

 with the third joint broken into subjoints all American? An 

 examination of our figures will show that they occupy, in struc- 

 ture, a position between Papirius and Smynthurus, for, if you 

 coalesce the subjoints of the terminal and subterminal regions, 

 the antennae become four-jointed, with a long terminal joint 

 broken into many sub-joints, that is, Smynthurid. 



It is impossible to identify species from such meagre and gen- 

 eral descriptions as that of P. novceboracensis Fitch, especially 

 when not accompanied with drawings. It is equally hard to do 

 so from alcoholic specimens of species soft bodied, and that 

 shfivel and change color as do Thysanourans. Good drawings 

 are essential. 



Whether we err in referring this form to a new species can 

 never be decided by the published description. The accompa- 

 nying more detailed description and drawings will, we hope, serve 

 a better purpose. The drawings were made by Mr. J. H. Emer- 

 ton, under the direction of the writer. Fig. i shows the ocelli 

 accurately drawn. Fig. 2 shows one of the suckers extended.
