Modified segments.— The seventh sternite (Fig. :t, VII st.) gradually narrows 

 towards the apex, whuh is broad and almost evenly rounded off in side-view. The 

 eii'lith tergite (VIII t.) bears several small bristles above the stigma, and one large 

 bristle accompanied by a row of fonr or live small ones below it. On the ventral 

 jmrtion of the eighth tergite there are about eight long bristles on the side and 

 about eight shorter ones proximally to them ; the apical margin, moreover, bears 

 two loiitr bristles and below them a thinner and shorter one and a still shorter 

 bristle. On the inside there are near the apex two or three short and stout bristles. 

 The stylet is nearly cylindrical from the base to the bristles. It is two and a half 

 times as long as it is broad at the base, and bears a long apical bristle and proxi- 

 mally to it on the under respectively outer surface two shorter ones. The 

 receptacnlam semiuis (Fig. 3) has a long, irregularly pear-shaped head, which 

 gradually merges into the short tail.

Craneopsylla gen. no v. 



All the American species hitherto jilaced in the genus Stephunocircus Skuse 

 (1890) differ in certain characters from the Australian forms and constitute a 

 well-defined genus. 



The maxilla is not elongate-triangular in side-view as in Stephanocivciis, but 

 irregularly elongate-ovate with the tip somewhat jiointed. The hindcoxa bears a 

 row of spines on the inner surface. The anal tergite is not separated from the 

 preceding segment by a broad membranons suture as in the ? ? of Stephanocircus, 

 and the stylet is at the most three times as long as it is broad proximally. 



Genotype : C. wolffhaeijeli Roths. (1900). 



Craneopsylla achilles spec. nov. 



S. Close to C. tcol/fsuhiii Koths. (19u9), of which it is most probably a geo- 

 graphical representative. The genitalia, however, differ so much that the new 

 insect must be regarded as a distinct species. Ajiart from these organs there 

 is hardly anything by which achilles can be distinguished from irol/l'sohiu. The 

 comb of the helmet contains thirteen teeth on each side, instead of eleven as 

 in the i of icolj'aohni. The genal comb consists of five teeth as in that species, 

 but the upper tooth is much smaller and more isolated from the rest in ac/tilles. 

 The pronotnm bears a comb of eighteen teeth and two rows of bristles, not three 

 as in irolffaohd. The mesonotum has likewise two rows, there being no additional 

 bristles dorsally in front of the rows. 



We are by no means certain of the homology of all the parts of the modified 

 abdominal segments of the $. As only a single specimen each of the c? c? of 

 tcolffmhni and achilles is known to us, we cannot therefore ascertain the homology 

 by making dissections, and hence have to describe and figure the organs as they 

 present themselves in the mounted specimens. In both species under discussion 

 the eighth abdominal tergite bears in the <? a slender (internal) manubrium on each
