PHILOUGRIA ROSEA. 461 
segments of the tail, is tuberculated, each tubercle 
emitting a minute seta at its top. The eyes are small, 
black, and conspicuous. The inner antenne are very 
conspicuous, extending beyond the front, and consisting 
of three joints with the tip setose; the outer antenne 
are composed of five joints, besides the slender flagellum, 
which consists of four articuli, terminated by a long 
brush of hairs; the basal joints of these antenne are 
armed with strong bristles arising from small triangular 
lobes. The lateral angles of the head beneath the orbits 
of the eyes are strongly marked. The terminal segment 
of the body is flat above, with the extremity truncate, 
and armed with several strong bristles. 
We believe that this species has only hitherto been 
found in Mr. C. Spence Bate’s courtyard and cellar, and 
that of neighbouring houses, at Plymouth, where it is 
tolerably abundant. Its habits agree with those of the 
rest of the genus, but it appears to frequent more humid 
haunts. It feigns death, but does not attempt to roll 
itself up, and is not quite so active as the other species.
