Family XLIX. Macrocerata s. Longicornia. Tarsi as in the 

 preceding family. Mandibles broad, triangular, with apex simple, 

 acute. Ligula mostly membranous, cordate, emarginate. Antennae 

 filiform or setaceous, mostly long, almost of the length of the body 

 or longer than the body. Form of the body elongate, depressed. 

 Eyes in many emarginate, a sinus receiving the base of antennas. 



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 larvae 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 Lucanus L.

 terior margin of thorax. Thorax conico-truncated, broader pos- 

 teriorly. Elytra mostly attenuated towards the apex. Body often 

 arcuate, with feet long. 



Leptura L. (in part), DEJ., LATR. Antennas remote at the base. 

 Thorax mostly not produced into lateral tubercles, with margins 

 smooth.
