We have not seen the specimen described and figured by Wagner, 
but we believe’we have correctly identified as bohlsi the undermentioned 
specimens received from Paraguay, Argentina and Ecuador. 
One £ from Paraguay, off Didelphys azarae, Dec. 1901; W. Foster. 
Two $ $ from Sapucay, Paraguay, off Didelphys azarae ; W. Foster. 
Two $ $ from Gran Chaco, Argentina, off Didelphys azarae, May 
1900; Mr Pride (per J. Graham Kerr). 
One $ from Ibarra, Ecuador, off Nectomys saturatus, May 1897; 
W. F. H. Rosenberg. 
(7) Rhopalopsyllus roberti Rothsch. (1905). 
Pulex roberti Rothschild (1905, p. 479, n. 1, t. 13, figs. 1, 2, Sao Paulo, off Nectomys 
and Didelphys). 
Closely related to R. bohlsi ; but roberti is larger than that species, and 
the bristles are much stouter, especially those situated on the head. 
There is an additional row of bristles dorsally in front of the two rows 
of the mesonotum and of the three rows of the metanotum. The long 
ventral apical bristle of the fifth foretarsal segment is stouter than in 
R. bohlsi. The apical bristles of the second hindtarsal segment are 
somewhat shorter than in that species. The eighth sternite of the J 1 
bears on each side a curved row of 5 or 6 bristles, there being no 
additional bristles in front of this row. The bristles on the dorsal side 
of the clasper are fewer in number than in R. bohlsi and there is a long 
bristle at the point where the clasper joins the dorsal portion of the 
ninth segment. The bristles of the ninth sternite of the £ are all 
practically of the same length. In the $ the seventh abdominal 
sternite bears a single row of long bristles, there being no bi’istles in 
front of the row, and the eighth sternite has fewer bristles than in 
bohlsi. 
We have both sexes from Sao Paulo, Brazil, off Didelphys aurita, 
found in November 1901 by A. Robert. 
(8) Rhopalopsyllus bernhardi spec. nov. 
(PL VII, fig. 6.) 
Likewise very closely related to R. bohlsi. The first midtarsal 
segment is somewhat shorter. The clasper of the </ bears fewer bristles 
than in R. bohlsi and roberti, there being a large bristle (broken in our 
single specimen) where the clasper joins the dorsal portion of the nin th
