THE MYKIAPODA OF NORTH AMERICA. 97 



This species shows relationship to F. einjinicnuix by the coxa? of cop- 

 ulation foot being provided with a long, straight spine. It also agrees 

 with the more eastern specimens of F. virgin intuit, by having the veii- 

 tral plates and coxa- spined. F. georgiana is described from numerous 

 specimens from Macoii, a few from Tallulah, and one from Lookout 

 Mountain. 



16. Fontaria tallulah, sp. nov. 



Diagnosis. Ventral plates and coxa- spiued as in F. yvorgiana, but 

 separated from that species by having the lateral carina' and posterior 

 margin of dorsal plates red; posterior angle of lateral carin;e rather 

 sharply produced. 



Habitat. Tallulah, Ga.; L. M. Underwood. 



2fype. Ace. 11)542, 20; U. S. Nat. Museum. 



Description. Brownish black, lateral carina* and posterior border of 

 each .segment red; antenna*, legs, and uuderparts yellow. Segments 

 depressed, anterior segment moderately attenuated; corrugated, es- 

 pecially posteriorly and on lateral carina' ; papilla* distinct: vertex snl- 

 cus distinct; occipital foveola* 2-4-2, antenna! and clypeal single (1+1). 

 Lateral earina- large, interlocking, posterior angle rather sharply pro- 

 duced. Repugnatorial pores large, placed on the upper margin of pos- 

 terior third. Ventral spines straight, stout, and conical, coxa- armed. 

 Length, 25""". 



F. tallulah seems to be only related to F. gcot-giana by having the 

 ventral plates and coxa* spined. In the pattern of coloration it ap- 

 proaches F. rubromarginata, but that species has the ventral plates 

 unarmed and therefore belongs to the same section as .F. corruuata, 

 rridcu. etc. This species is described from an apparently adult female. 



17. Fontaria rileyi, -sp. nov. 



Diagnosis. Brown, lateral carina- red: ventral plate, and coxa* un- 

 armed: copulation foot stout, flattened, end subsimilar to a bird's head. 



Tiipi'. Ace. 1!)542, 5, U. S. Nat. Museum. 



Habitat. Macon, Ga.: L. M. Underwood, &. 



hcscfijttion. Brown, lateral carina' red; antenna-, legs, and under 

 parts yellow. Segments moderately depressed, scarcely attenuated 

 anteriorly; very corrugated, papilla* not prominent; behind each pore 

 an indistinct black swelling. Vertex sulcus shallow; occipital, anten- 

 na!, and clypeal foveola' single. Lateral carina- large, interlocking, pos- 

 terior angle not much produced. Repugnatorial pores large, placed 

 on the posterior third of margin. Ventral plate unarmed: coxa- not or 

 very slightly armed; femora strongly armed; claws normal. Male: 

 Copulation foot stout, Hattcited, curved, end subsimilar to a bird's head.

This species belongs to the same group as /'. <<n-fii<jta, rriilr*, etc., 

 and should stand near the latter, as shown b\ tin- form of the copula- 

 lion tool. It is separated from /'. n-itlr:< by having the copulation foot
