thecoxreofprehensorial legs seem to convince me that they are not 

 markings peculiar to a male. 

 27 Geophilus smithi, sp. nov. 



Diagnosis.-ReUted to G. huronicus, but the coxal pores more numer- 

 ous 25-30; coxa? of prehensorial legs of about equal length and width; 

 pairs of legs of female 49; length 20-28-". 



Habitat.— Washington, D. C; J. B. Smith. 



Tune.—U. S. Nat. Museum. 



This species is very closely related to G. huronicus, but it seems to 

 be sufficiently distinct as shown by the number of coxal pores which 

 are 25-30 in number in smithi, but only 7 or 8 in Imronicus; also b 5 the 

 number of pairs of legs (huronicus, S 53-55, 9 5o-57). 



This species is described from two females, one of which is an adult, 

 the other being about three-fourths grown.

The specimens contained in the firsttwo vials seem to belong to that 

 phase of A sexspinosus which has been described by Meinert under he 

 name of S. georgicus. The only real tangible difference I can find be- 

 tween these specimens and the true sexspinosus is n the moderately 

 Jothed condition of the presternum, and I think it is best to consider 

 qeorgicus as not a valid species.

As shown by the character of the anal legs this species seems to be 

 sufficiently distinct from heros.
