This species so closely' resembles quadrisetosa 

 that a brief mention of the differences will suffice. 



The outer vertical bristles are well developed in 

 the males. The forceps when viewed from behind be- 

 gin to diverge at about half their extreme length 

 instead of near the base, and the tips are but little 

 convergent or even parallel; the posterior clasper is 

 much longer; the anterior clasper is bent forward 

 almost at the base and is more slender along the mid- 

 dle, with a broader tip. The transverse plate near 

 the end of the penis in front forms a more acute angle 

 with the body of the organ; the two shining black 

 processes arising just bej^ond this plate are much 

 shorter and the terminal liooks arising from the back 

 plate are larger, with a cleft apex. The fifth sternite 

 is generally shining black, somewhat more broadly 

 excised than in the other species. 



Female. There seem to be no tangible differ- 

 ences separating the female from that of quadrise- 

 tosa. 



Numerous males and females, Massachusetts; 

 New Jersey; Ohio; Indiana; Illinois; Tennessee;

Holotype. — Male, in collection of Massachu-

This is perhaps only a variety of quadrisetosa; 

 like the latter, it is an excrement-feeding form.
