10 EPi. This explains the statements made by Davis (1939b) concern- 

 ing the presence of clawlike structures on this process (also see Ross, 

 1940b). 



OLIGEMBIA (OLIGEMBIA) BREVICAUDA Ross 

 FiGUKE 101 



Oligemhia hrcvicauda Ross, 1940b, p. 640, figs. 1, 8-10. 



Eolotype.— Male, U. S. N. M. No. 53980. 



Type data.— St. Croix, Virgin Islands, June 20, 1939 (H. A. Beatty). 



Remarhs. — Recently an additional male specimen of this species 

 was studied by the writer in the United States National Museum col- 

 lection. It is labeled "under rubbish," Lower Love, St. Croix, Virgin 

 Islands, August 1940 (H. A. Beatty). This specimen reveals a note- 

 worthy intraspecific variation and the fact that 10 LP of the holotype 

 specimen had been broken off midway in its length.

Figure 101. — Oligemhia brevicaxida Ross (Virgin Islands): Left tergal process and process of 

 left cercus-basipodite. Explanation of sj'mbols on p. 403. 



The left tergal process, 10 LP (fig. 101), is not short as originally 

 described but is actually similar to that of hubhardi. The mesal proc- 

 ess of the left cercus basipodite terminates as a pair of stout "claws," 

 also as in hubhardi, whereas this process tapers to an irregular point 

 in the holotype. 



These findings give stronger evidence of the close relationship of 

 hrevicauda and hubhardi, although the two species are separable by 

 means of numerous characters.
