Smit, F. G. A. M.: The zoological results of Gy. Topál's collectings in South Argentina 4. Siphonaptera

the zoological results of gy. tota l's collectings : siphonaptera 425 360 m.; 15 2$, 6—19. VIII, 360 m. ; from Akodon olivaceus brachiotis or Akodon longipilis suffusus: 1 3, 14—19. VI, 360 m.; from Oryzomys longicaudatus philippii or Akodon olivaceus brachiotis: 1 3 1 $, 5— 11. VIII, 360 m.; from Oryzomys longicaudatus philippii or Akodon olivaceus brachiotis or Akodon longipilis suffusus: 1 3, 7 — 9. IV, 480 m. It was a great pleasure to see a fine series of this really fascinating flea of which only four specimens (2 3 2 $) had hitherto been collected (in the neighbourhood of San Carlos de Bariloche, ex Akodon varius neocenus, Akodon sp. and Euneomys dabbenei). As is shown in the original description, the deve­lopment of the pronotal ctenidium is bizarre — this structure was, as is usual, depicted by JORDAN from a lateral view; the dorsal view of the pronotum is shown here in Fig. 4. JORDAN (1953: 180) remarked that „The dorsal area [of the pronotum] is drawn out into a long process which reaches to the end of the mesonotum and bears a comb, the spines of which project downwards. " Actually, as can be seen from Fig. 4, the spines are projecting more sideways Mg. 4. Barrerupsylla excelsu JORDAN.

The specimen from which Fig. 4 was drawn is mounted without the application of any pressure, either laterally or dorso-ventrally . Plocopsylla wolffsohni (ROTHSCHILD. 1909) From Oryzomys longicaudatus philippii: 1 3, 12 13. VI, 360 m.; from Akodon olivaceus brachiotis: 1 3, 13. VI. 360 m. ; 1 $, 15-16. VIII. 380 m. ; from Akodon longipilis suffusus: 1 3 1 $, 18. VI, 360 m. ; 7 3 7 ?, 6—19. VIII, 360 m. ; 3 3 2 $, 5. IX, 300 m. ; from Akodon olivaceus brachiotis or Akodon longipilis suffusus: 4 $ 12. VI, 360 m. ; 2 3 1 ?, 14—19.
