few bristles, which are ventral in position. The following four sternites have each 

 a subapical row of from six to eight bristles, and very numerous hairs proximally of 

 that row. The seventh sternite is bisinuate (fig. 1 ; as the segment is broken, the 

 ventral outline of the figure may not be correct). 



Leqa : — The mid and hind coxae have two bristles and a short hair posteriorly 

 near the apex. The mid and hind femora bear on the inner side a subventral row 

 of small hairs, and posteriorly four or five subventral bristles. The tibise are densely 

 covered with hairs on the outer side. The tai'si are long and slender. The first 

 fore-tarsal segment equals the second in length, while the first mid-tarsal one is 

 longer than the second, its longest apical bristle reaching the middle of the second 

 segment. The first hind-tarsal segment bears eight pairs of bristles on the posterior 

 side, and about twelve pairs on tlie anterior side. The longest apical bristle of the 

 second hind-tarsal segment reaches to the apex of the third. The fourth hind-tarsal 

 segment is about three times as long as broad, while the fifth segment is a little 

 shorter and narrower than the third, its bristles being short and slender. The pro- 

 poi'tions of the tarsal segments are : —

Modified segmeyitfi : — The eighth tergite has a few bristles above the stigma, but 

 none below it. The bi'istles at and near the apical and ventral edges of this tergite 

 are slender, but not long. The eighth sternite is small and bears at the tip three 

 bristles on each side. The sensory plate is very strongly convex behind ; it is not 

 encircled by a smooth and strongly chitinised ring. The stylet is cylindrical, widen- 

 ing a little basally being about three times as long as it is broad proximally. The 

 anal sternite is sti'ongly convex beneath in the centre, and bears very numerous 

 hairs. Length. 4*8 mm. 



"We have one ? of this interesting species, collected by Mr. 

 Alexander Morton off a Tasmanian rat at Hobart, Tasmania.

?. Near (77?. wihado, Eothsch. (1904), and Cli. fricliosn, Koh. 

 (1903), differing: specially in the bristles of the abdominal ters^ites. 



Head : — The rostrum is shorter than in the above-mentioned species. The 

 occiput bears three bristles behind the base of the antennae, and a lateral row of 

 four in the middle, besides the subapical row. 



Thorax : — The epimerum of the metathorax bears two rows of bristles, the 

 first row consistingr of seven or eight, the second of six. 



Abdomen : — The first three termites bear three rows of bristles, the anterior row 

 being irregular and incomplete, while the other two rows are continued below the 

 stigma on the second and third segments, there being eight or nine bristles below 

 the stigma. On the foui'th tergite there are two bristles beneath the stigma, and 

 one on the other termites, while there are three or four hairs above the stigma on these 

 segments, apart from the postmedian row. Thetergites are similar in shape to those 

 of frichosa and mikado, but do not extend quite so far down. The sternites are also 

 similar to those of the above-mentioned species, that of the seventh segment bearing 

 in the type specimen two rows of bristles.
