1886. PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. 345 



Habitat.— Tallnlah, Ga.; L. M. Underwood. 



Type.— Ace. 19512,20; 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, espec- 

 ially posteriorly and on lateral carina?; papilla? distiuct; vertex sulcus 

 distinct; occipital foveola? 2+2, anteunal and clypeal single (1+1). 

 Lateral carina? large, interlocking posterior angle rather sharply pro- 

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

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

 Length, 25 mm . 



F. tallnlah seems to be only related to F. georgiana by having the 

 ventral plates and coxa? spmed. In the pattern of coloration it ap- 

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

 unarmed aud, therefore belongs to the same section as F. corrugata 

 evides, etc. This species is described from an apparently adult female. 



17. Fontaria rileyi, sp. iiov. 



Diagnosis. — Brown, lateral carina? red ; ventral plate and coxa? un- 

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



Type. — Ace. 1951:2, 5, U. S. Nat. Museum. 



Habitat. — Macon, Ga. ; L. M. Underwood, $ . 



Description. — 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, anteunal, 

 aud clypeal foveola? single. Lateral carina? large, interlocking, posterior 

 angle not much produced. Repuguatorial pores large, placed on the 

 posterior third of margin. Ventral plate unarmed; coxa? not or very 

 slightly armed ; femora strongly armed ; claws normal. Male : Copu- 

 lation foot stout, flattened, curved, end subsimilar to a bird's head. 

 Length, 43.5 mm ; width, 10.2 n,ra . 



This species belongs to the same group as F. carrugata, evides, etc., 

 and should staud near the latter, as shown by the form of the copula- 

 tion foot. It is separated from F. evides by having the copulation foot 

 more flattened, especially the end, which is cylindrical iu evides ; be- 

 sides F. rileyi attains a larger size. 



This species is described from a male specimen. 



I take great pleasure in dedicating this species to Dr. C. V. Riley, 

 United States Entomologist, to whom I am indebted for numerous 

 favors. 



18. Euryurus erythropygus australis, sub. sp. nov. 



Diagnosis. — Similar to E. erythropygus, but the lateral cariure larger, 

 the margin less swollen, more straight, and the deuticules larger. 

 Upper branch of copulation foot five times as long as the lower. Body 

 slenderer. 



Type.— Ace. 19542, 18, Indian Springs, Ga. ; L. M. Underwood, $ .
