CASE boughs of trees, in moss, among decaying leaves and similar 

 situations. There are only two species of this 

 genus found in Britain, the present and another 

 named O. villosa. The latter is yellow, and has 

 the entire body mottled with black, whereas O. 

 cincta, although very variable and often yellow 

 mottled with black, has always the third seg- 

 ment of the abdomen black. The whole insect 

 is sometimes almost entirely black. The body 

 in this genus is without scales.

The antennae in the genus Tomocems are ordicseiu dncta. 



0.25 of an inch in length. 



long (in this species very long and rolled up 

 at the apex like a piece of tape) four-jointed, the two terminal 

 segments being multiarticulate or ringed. The body is clothed 

 with scales and the eyes are seven in each group. 



The colour of T. longicornis is leaden unless where the scales 

 are removed, when it is yellow. The antennae are longer than 

 the body. It is a large species, being 

 one-fifth of an inch in length, found in 

 England and on the Continent, under 

 logs, &c., throughout the year.
