funiculus, and the third joint of the tarsi simple; they 
are sometimes pubescent, and always elongate, nar- 
row, cylindrical, and more or less truncate behind, 
especially in the male, which sex also often exhibits 
strong spines on the edges of the truncation. They 
abound in larch-trees, elms, &c., and their larvae 
resemble those of Scolytus in miniature; the pupa) 
differing, however, in the possession of two spines at 
the apex of the abdomen. 
Lastly, Platypus cylindrus (Plate XIII., Fig. 2), 
found rarely here, and chiefly in the New Forest, 
departs from the others (amongst other characters) in 
its very short antenna), which have a long basal joint, 
a very compressed four-jointed funiculus, and an 
extremely large, flat, round club ; its widened and 
flattened front femora ; very short tibia), short hind 
legs, and extremely long and slender tarsi, which are 
longer than the femora and tibiae, and of which the 
basal joint is longer than all the rest put together, and 
the third joint is simple. Its larva, which feeds upon 
oak, differs from that of Scolytus in being short and 
straight, somewhat truncate behind, with a large head 
and several rows of tubercles on the sides. 
It should be remarked that the Bostrichidx, above 
associated with the Malacodermata, present great 
resemblance to certain of this family ; in which, indeed, 
they have been placed by Latreille and other authors. 
Put in the Bostrichidx the larva) have legs, which are 
wanting in those of the Scolytidx ; and, although the 
perfect insect appears in both to have only four joints 
to the tarsi, yet in the former there aro five, the basal 
joint being very small; whilst in the latter the fourth 
joint is obsolete, or confused in the middle of the lobes
