566 WEST AFRICAN INSECTA AND ARACHNIDA RILEY. 



In tlie Coleoptera, witli the aid of Mr. M. L. Linell,Ji certain number 

 of species were made out and the residue were then sent to Dr. David 

 Sharj), of Enjiland, who has deteiinincd tliem, wlicn necessary, by 

 coiu])aris()n with the coHectiou in tlic Britisli IMuseum. Mr. < Uiampion, 

 of the British Museum, has <>iven a few of the names in the families 

 Cistclida\ La^riida^, and Aiithicida^ to Dr. Sharp, while Mr. Jacoby 

 has examined some of the Chrysomeli(he and Mr. (Jorham the Endo- 

 mychida\ 



The Orthoptera have been determined by Mr. Henri d(^ Sanssure, of 

 Geneva, Switzerland. 



The Pseudoneiiroptera were sent to Mr. P. P. Calvert, of I'hiladel- 

 phia, Pa., who describes the new species. 



The Hemiptera were sent to Mr. A. L. Montandon, of Bucharest, 

 Roumania, who has given me most of the determinations. 



In the Arachnida the families Attidse and Lycosida? have been 

 studied by my assistant, Mr. Nathan Banks, and his report, with de- 

 scriptions of the new species, is appended. The remaining Arachnids 

 have been referred to Dr. George Marx, whose report, with descriptions, 

 is also included. The Myriopoda were sent to Messrs. O. F. Cook and 

 G. N. Collins, of Syracuse University, and as five of the seven species 

 comprising this material were, according to their decision, entirely new 

 to science, I have appended their report in the form in which it was 

 received.* 



I have added such details as to number of sjiecimens and locality as 

 may have value. My sincere thanks are due to all the gentlemen 

 named for their courteous aid in the determination of the material.
