MARGAROPUS 



INTRODUCTION 



The genus Margaropiis , closely related to Boophilus and con- 

 fined to Africa and Madagascar, consists of only two species, M. 

 winthemi Karsch, 1879, of southern Africa and Madagascar, and H. 

 reidi sp, nov, of the Sudan. Earlier assertions that M. vfinthemi 

 is a South American tick apparently are erroneoiis. "" 



Usual remarks in the introductory sections for each genus 

 treated in the present work are, in the case of Margaropus , in- 

 corporated into the text below and do not require repetition 

 here. 



IllTostrations of nymphal M. reidi sp. nov. and of M. winthemi , 

 together with a review of the Tatter species, are given~in the 

 APPENDIX, pages 896 to 905. The unexpected circimstance of the 

 very recent acquisition of the new species necessitates this treat- 

 ment.

 generic key, are sufficient to comprise an adequate diagnosis for 

 each species in this genus.
