Ennearthron. | SERRICORNIA. 213 
ENNEARTHRON, Melliéc. (Lntypus, Redt.) 
According to the Munich eatalogue this genus contains thirteen 
species, two from Europe, and the remainder from North and South 
America, Cuba, and South Africa; several European species have, 
however, been described since, and the genus is probably a much more 
extensive one than is at present known; in fact, this is probably the 
case with all the genera belonging to the family, as, from their minute 
size and inconspicuous appearance, they are often passed over by 
collectors ; they are distinguished by their 9-jointed antennz, of which 
the first two joints are large, the third slender and elongate, the 
next three very small, and the last three form a large and distinct 
club.
