synonymous with apicatus, Bl., which is the type of the genus 

 Stylo-thorax, Bertkau (1883). P. furcillatus, Menge, was removed

 ( — acuminata, Bl.), therefore remains, and must of necessity be 

 the type of Phalops. The name Phalops is, however, preoccupied, 

 and I therefore propose the name Jacksonia to replace it.
