Genotype — N^eoconocephalus subulatus [Conocephalus suhulatus] 

 (Bolivar), selected by Karny, 1907. 



Differential Generic Characters. — When compared witli the most 

 nearly related genus, Euco7iocephalus, the present genus is given 

 by Karny as differing in the form of t he lateral lobes of the prono- 

 tum which are deeper with ventral margin obtuse-angulate or 

 rounded, and in the tegmina which have the costal vein abbreviate 

 or obscure and more distinctly divergent from the humeral vein. 



History. — -Kirby, in 1906, restricted the name Conocephalus to 

 the genus called Anisoptera by Latreille in 1829, and Xiphidion 

 b}^ Serville in 1831, but his views on tautonymic generic and spe- 

 cific names impelled him to use the name Anisoptera for that genus 

 and, in place of Conocephalus as generally understood by authors, 

 he used the name Conocephaloides, which had been proposed by 

 Perkins, in 1899, for an aberrant form of the subfamily from the 

 Hawaiian Islands. The genus Conocephaloides is, however, dis- 

 tinct from the present aggregation. Karny, in 1907, recogniz- 



' Published with the aid of the Orthoptcra Fund.
