Lcnsjth, 4'fi mm. 



We have one ? example of this species from Liiunceston, Tasmania, from 

 J)ns>/urus vivenim/s, collected by Mr. A. Simson. 



'■\ Ctenopsyllus ellobius spec. nov. (PI. XIV. fig. 13. 14. 1.5). 



Head. — The frons is evenly and strongly ronnded, the lower portion sloping 

 backwards, especially in the d (PI. XIV. fig. 13). There is a vertical row of five 

 genal spines. The vestige of an ej^e is placed above the uppermost spine. The side 

 of the frontal portion of the head bears one very long bristle, and several shorter 

 ones, as shown in the fignre. The occiput bears three oblique rows of bristles, 

 besides the snbapical row. The first antennal segment is large. The second 

 is produced apicad anteriorly, the projection extending in the ? beyond the middle 

 of the clnb, and in the J to the fourth segment of the club. The rostrum e.xtends 

 to the snbapical row of bristles of the forecoxa. 



Thorax. — The pronotum bears two rows of bristles and a comb of twenty-eight 

 teeth. The mesonotnm has two slender snbapical spines on each side, and three 

 rows of bristles, bearing numerous additional hairs, between the first row and the 

 base. There are three oblique rows of bristles on the metanotum, and laterally near 

 the base an irregular fourth row. The apex of the metanotum is denticnlate. The 

 epimernm of the metathorax bears four more or less irregular rows of bristles, 

 twenty to twenty-three altogether. 



Abdomen. — The tergites 1 to (i are denticulate dorsally at the apex. The 

 second to fifth bear laterally, not dorsally, short stout apical spines, which vary 

 in number, there being in the S on one side G. 0. 9. 2, and on the other 6. G. G. 2, 

 while in the ? the numbers are 4. 4. 6. 0, and 4. 4. 4. 0. There are four rows of 

 bristles on all the tergites. The anterior row, however, is represented in the <? by 

 a few dorsal hairs only. The stigmata are pointed behind, and stand on the middle 

 segments above the third or fourth bristles of the last row, but much nearer the 

 base of the segment. The seventh tergite bears three heavy apical bristles, the 

 middle one being more than twice the length of the dorsal one. The basal sternite 

 has a number of hairs at the ventral edge, and bears an oblique lateral row, the 

 hairs in this row being more numerous in the ? than in the S. The stcrnites of 

 segments 3 to 6 bear in the ? a row of four or five long bristles, in front of which 

 there are three rows of shorter ones, the anterior row being irregular. In the c? the 

 number of bristles is reduced, there being only one row before the long bristles, with 

 some additional hairs in front, representing the two anterior rows of the ? . The 

 number of bristles is larger on the seventh sternite, especially in the ? , which bears 

 seven bristles in the last row. 



Legs.— The hindcoxa, which is devoid of a comb of spines on the inner surface, 

 has four bristles posteriorly at the apex. There is an irregular lateral row of 

 minnte hairs on the outer side of the forefemnr, and two snbapical ventral bristles, 

 there being in the S several additional small hairs above that row. The mid- and 

 hindfeniora bear ventrally near the apex on the outer side three bristles, and on the 

 inner side one small hair. The outer side of all the tibiae is covered with hairs, 

 these hairs iieing arranged in three or four irregular rows on the hindtibia. This 

 tibia liears at the dorsal edge nine stout bristles of nearly equal length, four of them 

 being accompanied by a long one. The bristles of the tarsi are numerous and 

 rather stout. The longest apical one of the second hindtarsal segment does not
