This distinct genus, which can be readily distinguished from any other belonging to 
the Scutellerine known to our fauna, by the elongated and depressed head, contains 
three species, one of which is now for the first time described. The other two also 
belong to the Neotropical region, but doubtless others remain to be discovered.
