We have examined and made drawings of two specimens of this 

 species, the holotype, a female, and a paratype with extended female 

 genitalia; both specimens are labeled, Orlando, Florida, May 26, 1922, 

 in decaying leaves and twigs, H. E. Ewing collector. 



The foretarsus (figs. 87-88) has a clavate t 1 and a small, rather 

 blunt, lancetlike t3; d:p=84:40(=2.10). The most characteristic 

 features are the very long sensillae b and c, and the short f and g; f and 

 g are rather close; e is in the middle between d and f; b' is missing 

 (a' given erroneously as b' in fig. 88). The empodium is short; 

 e:u=4:27(=0.15). 



The comb of abd. VIII (fig. 92) is very peculiar, having teeth which 

 appear to be coalesced nearly to the tip. There are about 8-10 teeth, 

 and only the outermost tips of them are free, but their borders seem 

 to be visible within the lamina. 



The filamento di sostegno (fig. 93) is very short. 



The characters mentioned are identical in the two specimens and 

 there seems to be no doubt about the specific rank of the species on 

 account of the large sensillae b and c of the foretarsus and the very 

 characteristic comb. The species belongs to the genus Acerentulus. 



Acerentulus aureitarsus Ewing 



Figure 94-103 

 Acerentulus aureitarsus Ewing, 1940, p. 544. 



Only two slides are present of this species, the holotype, a maturus 

 junior, labeled, Difficult Run, Virginia, Sept. 4, 1938, Snodgrass 

 and Ewing collectors; and a paratj^pe, also a maturus junior, labeled, 

 near Prospect Hill, Virginia, Sept. 25, 1921, in decaying leaves and 

 twigs, H. E. Ewing collector. We have also examined four specimens 

 determined by Bonet with the label, Dead Run, Virginia, May 29, 

 1948, E. A. Chapin collector.
