NOTES ON THE SIPIIONAPTEBA FROM THE ARGENTINE 

 DESCRIBED BY THE LATE PROFESSOR DR. WEYENBERGH. 



By K. JOEDAN, Ph.D., and the HON. N. CHARLES ROTHSCHILD, M.A., 



F.L.S., F.E.S. 



TTTEYENBERGH iu 1881 * described seven species of fleas. Thongt ever}- 

 VV name is ennmerateil in the Zooloi/ical Record (of the Zoological Society 

 of London), they have all been overlooked by subseqnent authors. The descriptions 

 in qnestion do not give those characters which are essential for the recognition 

 of species, the absence of all figures being, moreover, a great disadvantage in this 

 publication. We have, therefore, abstained in former papers from trying to identify 

 any of Weyenbergh's species with those we have from South America. 



Professor Dr. Doeriiig, of the University of Cordoba, Argentina, has most 

 kindly sent us a set of cotypes of all the species described by Weyenbergh, and 

 we take this opportunity of reiterating our thanks to him. The specimens were 

 glued on cardboard, as was formerly the custom. In order to examine them 

 carefully we had them mounted in balsam. Some of Weyeubergh's names, as 

 we expected, refer to species described later by other authors, while some others 

 apply to species already described before Weyenbergh, one other again designating 

 a species which has not been rediscovered. 



In the present pajier we discus-s in detail all the following species described 

 by Weyenbergh as new in the paper mentioned and in a i)revious one:t 



Pulex yrossitentris, Pulcx nasuae, 

 Ceratophijllus i-ufulus, „ obscurus, 



„ isidori, „ concoloHs, 



Pulex {IIectopsijlla?)testudo, „ caricohi. 



Family SARCOPSYLUDAE. 



The family comprises three genera : Dertmtophilus Guer. (= Sarcopsylla 

 Westw.) ; Ecltidnophriga Olliff (= Aiyopsylld Enderl. = Xe.stopfi>jU(( Caker), and 

 Ilectopsijlln Frauenf. (= JUii/ncIiopsi/llux Haller). 



Karsten (1804)emjiloyed the name Rhi/nclioprion Oken instead of Dennntophiltts 

 (= Sarcopsijlla) for the dhigoe, and Baker followed suit iu 1904 and 1005, calling 

 the family Jibjnchopnonidae. We remark (1) that Phynchoprion Oken is 

 ])rcoccnpied by Rb/nclioprion Herm. |), and (2) that Rhi/iicho/iricw Oken was 

 not a term proposed for the Cliigoe, but for mites— the Chigoe, which Oken knew 

 only from figures and descriptions, being provisionally put into the same genus, 

 not as Rhynchoprion penetrans, but as Pulex penetrans. Wliatevcr rules of 

 nomenclature one adheres to, Rliijnclmprion cannot possibly be retained for Linn6's 

 Pulex penetrans. Baker calls Rhynchoprion " the older and only correct name " ; 

 but did he compare Oken, Natury. iii. p. 402 (1815) ?
