more flattened, especially the end, which is cylindrical in 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. Kiley, 

 United States Entomologist, to whom I am indebted for numerous 

 favors. 



18. Euryurus erythropygus australis, subsp. nov. 



Diagnosis. — Similar to JB. erythropygus, but the lateral carina? larger, 

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

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

 slenderer. 



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



When compared with E. erythropygus this neAv geographical species 

 plainly differs from it by the characters given. The lateral margin of 

 carinas are also slightly crenulate and the anterior is somewhat serrate. 

 Length, 28 mm j width, 3.4 mm . 



The exceedingly long branch of the copulation foot at once separates 

 australis from the true erythropygus. The inner tooth is also absent, 

 but this is subject to slight variations in erythropygus. 



The above notes are taken from a male which is slightly broken. 



19. Polydesmus branneri Bollraau. Ace. 19542, 23, Tallulah, Ga. ; L. M. Underwood. 

 These specimens are all females, and I refer them to this species with 



some doubt, but as they are from the region in which P. branneri is 

 found they must belong to that species and not to P. serratus, which is 

 not quite so southern in its range.
