IV. Eecords of Blood-Sucking Insects and other Arthropods 



from Sierra Leone. 

 The various blood-sucking insects and other arthropods which have been found 

 in Sierra Leone have been referred to in different places in the Narrative, but it 

 has been thought advisable to collect these and place them in tabular form. 

 This list, however, cannot be regarded as complete, as a large number of 

 specimens collected by the author still await identification, and a considerable 

 number of these will undoubtedly prove to be new. It will be seen from the 

 following list that quite a number of species have been recently recorded from 

 Sierra Leone for the first time, and there can be little doubt that several more 

 still remain to be discovered. 



The distribution records of the various species are very scanty, and it is to be 

 hoped that those whose inclinations turn that way will collect each and every 

 species, and by keeping exact data help in mapping out the distribution areas of 

 the different genera and species.
