Family XLIX. Macroceratas. Longicornia. 'Tarsi as in the 
preceding family. Mandibles broad, triangular, with apex simple, 
acute. Ligula mostly membranous, cordate, emarginate. Antenne 
filiform or setaceous, mostly long, almost of the length of the body 
or longer than the body. Form of the body elongate, depressed. 
HKyes in many emarginate, a sinus receiving the base of antenna. 
The goat-beetles, or long-horns. These insects usually live a long 
time in the state of larva and then reside in different parts of plants, 
especially in the inside in the wood, whence some species may become 
very injurious to the growth of trees. The larve have very short 
feet, or are quite destitute of them, and are vermiform, with rings 
strongly marked as though by constriction. The goat-beetles have 
some affinity with the group of the Lucanidea amongst the lamelli- 
cornia; this is however exaggerated, when some writers wish on that 
account to place this family in the neighbourhood of Zucanus L.
