As will be seen by the large iiuinlier of starred geuerti in tlie above 

 tables, our species of this family liave been very little stiitlied, and 

 on this account a tolerably full synopsis is given. Of the 175 genera 

 characterized, only 59 aj)pear in the List of described s])ecies given 

 further on. Many of the genera have been recognized in collections, 

 but descriptions of the species have not yet been published, e.g. 

 Xotaspis, Halidea, Phcenodiscus, Centrodora, Mmhogader, Rhopaliciis, 

 Caratomiis, Ropirocerua, Bcjihndfi, Pirene, Ophioneurm, etc. 



The genera Metapelma Westw., Paphagus Walk., Glijphe ^^ alk., 

 Ejiidenia Westw., Norbaniis Walk., Tetracnonm Westw., and ^ic-//(^s 

 Walk., of whicli species have been described as occurring in our 

 fauna, are so insutHciently characterized, that Mr. Howard lias been 

 obliged to omit them in the synojitic tables. 



Before leaving this subject, the compiler desires to gratefidly ac- 

 knowledge his thanks to Mr. Howard for tiie valuable information 

 and aid he has most kindly given him, especially in preparing the 

 list of our genera and species that have been described of this family, 

 and also of the l*roctotrupid;e, in which grou|)s he is the only recog- 

 nized authority in this country.
