3 Parapsyllus coxalis spec. nov. (PI. X. figs. 1, 2). 



A very near ally of /'. rori//t HothscL. (I'.iii4), but distingnisbeJ at ouce by 

 the peculiar foreco.va. 



In both se.xes the foreco.xa is strongly widened jiosteriorly near the base 

 (PI. X. fig. 1), as shown in the figure. It bears a transverse row of slender 

 bri.stles near the base, and farther down a row of strong bristles. At the hinder 

 edge just below the widest point of the coxa there are two very stout bristles, 

 and lietween these bristles and the apex of the coxa there is posteriorly only one 

 more bristle, which is jilaced at some distance from the hind edge. 



The fourth tarsal segment, moreover, is shorter than in P. cor////, being twice 

 as broad as it is long in the foretarsus and vi'ry little longer than it is broad in 

 the hindtarsus. The fifth tarsal segment also is broader than in /'. rori/fi, being 

 half as long again as it is broad in the foretarsus. The hindfcmnr bears a row of 

 7 to 1 1 bristles on the inside, and the hindtibia to 12 on the outside, whicli 

 are often arranged in two rows in the c?. The longest apical bristle of the 

 hindtibia of the ? does not extend to the subapical pair of bristles of the first 

 tarsal segment, while in the t? this bristle reaches beyond the apex of the 

 first tarsal segment. Tlie first and second hindtarsal segments have 4 very long 

 and slender apical bristles, the longest of the second segment reaching nearly to 

 the tij) of the fifth segment (claws excluded). 



The genitalia of the <J also show some consjiicuous differences. The movable 

 process of the clasjier is shorter tlian in J', coci/ti, and bears a row of C or 7 slender 

 hairs along the hinder edge from the base to the apex. The ninth sternite 

 (PI. X. fig. 2) more nearly resembles that of P. corfidii Rothsch. (1904), and 

 is distinguished by bearing numerons hairs at the apex and by the shape of the 

 vertical jiortion as shown in the figure. The bristles at the apex of the eighth tergite 

 of the ? are more numerous than in P. coci/ti, and the shorter ones stouter. 



We have a series of both sexes from Valparaiso, ( 'hile, found by .1. S. ^Volf}'sohn 

 on Octoilon degus. 



3. Parapsyllus australiacus spec. nov. 



ParapmjUus lurifiiconiis Jord. & Rotli.sch. (uec Enilerl., err. detenu.), Pum^ilulnri;/ i. p. S.'j. t. '2. 

 fig. 12, t. 4." fig. 5, t. 7. fig. 3 C1W8). 



When describing the present insect in the jilace ijuofed we said that our 

 specimens did not exactly agree with Enderlein's figures, and might be a closely 

 allied species. Dr. A. C Oudemans, who has had an opportunity of corai)aring a 

 cotype of lonc/icornis with our insect, now informs us that our identification was 

 indeed erroneous. It therefore becomes necessary to separate our species under 

 a name of its own, and we j)ropose to call it uKuli-dlidciis. 



Wt' have two pairs taken off E/idi/jilula minor on iiird Island, near Perth, 

 West Austriilia, by J. P.urton I'leland. 



4. Ceratophyllus graphis sjjec. nov. (PI. X. figs. 3, 4). 



(J ?. In the shape and the bristles of the head somewhat resembles C pol- 

 lionis liothsch. (I'JUo), but is abundantly distinct.
