Before the expedition to Central Australia, organized and equi}>pe<l 

 by Mr. Hoi'ii twenty years ago, no Heniiptera (and scarcely any insects 

 .at all) were known from those region.s. The collections brought home by 

 the expedition are therefore of unusual intere.st. The Hemiptera 

 are not represented by a great number of species, nor could tlicv 

 be expected to be so, considering the aridity of the territory. More 

 recently Central Australia has been visited by Mr. H. J. Hillier, 

 whose collections are now in the British Museum. They were made 

 east of Lake Eyre, whereas the Horn expedition explored the tracts 

 west and north-west of this lake. Of the Heniiptera collected by Mr. 

 Hillier some new species, mostly Pentatomidae (three of which Avere 

 also found by the Horn expedition), have been described by Mr. 

 Distant, but so far as I knoAv he has not yet published any list 

 of all the collected species.
