(2? in both sexes). They are ornamented with fleshy processes, of 
which the larger are placed in circlets round the ends of the 
developing segments of the antennae of the adult, and the smaller 
round the middle of each of these segments except the long basal 
one on which they are more numerous. ‘The abdomen is armed on 
either side with a series of long, fleshy, more or less forwardly- 
directed processes, on to the end of each of which a large and more 
or less backwardly-directed spine is articulated. 
A considerable number of Cucujid life-histories have already 
been worked out wholly or in part, and the following is a list of 
the descriptions known to me.
