Family AGRGECIID^. 



This family is small, when we consider the number of its repre- 

 sentatives, as compared with such important groups as the Pseudo- 

 phyllidae, Copiphoridae, and Phaneropteridae. Nevertheless, as Dr. 

 H. Karny remarks in his introduction to the paper dealing with the 

 group in the " Genera Insectorum," it contains fifty-eight genera and 

 two hundred and six recognized species. The family is almost entirely 

 tropical. At least thirteen genera are known from the neotropical 

 regions. These may be characterized as follows: 



Synopsis of the Neotropical Genera of Agrceciid.'E. 

 A. Prosternum smooth, not armed with spines. Lobes of the mesosternum 

 broad, either dull three-sided or rounded, not thorned or spined; the lobes 

 of the metasternum rounded. 



b. Anterior tibiae flattened above Hyperomems Redtenbacher. 



bb. Anterior tibiae rounded or terete above. 



c. Tegmina well developed, or at least more than half as long as the ab- 

 domen. 

 d. Fastigium of the vertex surpassing the first antennal joint, the apex 



bent downwards Erechthis BoUvar. 



dd. Fastigium of the vertex not surpassing the first antennal joint, 

 conical. 

 e. Tegmina greatly surpassing the apex of the abdomen . . Subria Stal.
