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 antennae are very 

 conspicuous, extending beyond the front, and consisting 

 of three joints with the tip setose ; the outer antennae 

 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 antennas 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.
