Subfamily I. MEGALOPINtE. 
Body elongate, often flattened above ; head frequently but not 
always constricted behind the eyes, the latter of variable size, 
deeply emarginate ; the terminal joint of the palpi elongate and 
pointed ; antennae short, the terminal joints more or less trans- 
versely widened, sometimes dentate, the basal joint inserted in 
front of the eyes, close to the inner margin. Thorax transverse, 
without lateral margins, often with an anterior and posterior 
groove, occasionally tuberculiform at sides. Elytra irregularly 
punctured and frequently pubescent, their epipleurae absent. 
Prosternum very narrow or indistinct, the mesosternum either 
extremely narrow and linear or entirely hidden. The metasternum 
sometimes raised at each side into a high elevation often of conico- 
truncate shape. The legs robust, with the posterior femora 
strongly incrassate and often armed with a tooth in the male ; the 
tarsi widened, pubescent, the claws very long and simple. 
This subfamily is more fully represented in South and Central 
America than in the East whence only two genera and a small 
number of species are known at present. These insects may 
be distinguished from those belonging to any of the preceding 
subfamilies by the short antennae, which have their terminal 
joints more or less strongly transverse and serrate. In this 
respect they resemble the Clytrince in which there is, however, 
a distinct lateral thoracic margin which is absent in this.
