PHILOUGRIA. 455 
dually elongated to the fifth joint. The flagellum con- 
sists of four or five slender joints, generally terminated 
in a small pencil of seta. 
The body is elongate-ovate, and the tail is considerably 
narrower than the former, with the lateral-posterior 
angles of the second and three following segments pro- 
minent; and the terminal segment is broad and truncate 
at its extremity, with the terminal caudal appendages 
(uropoda) of considerable size, and partially covered, 
with the basal portion, somewhat triangular, affixed in a 
notch in the underside of the posterior margin of the 
terminal segment. The outer ramus is long and acumi- 
nated, terminating in a seta; the inner slender and 
acuminated, more than half the length of the outer. 
The species are very active, and reside in damp situa- 
tions, thus agreeing with Philoscia.
