This species differs from Thopha saccata, A. &, S., the only 

 other described species of the genus, by the much more strongly 

 sessile eyes, a character alone which will instantly separate the 

 species. Besides this structural feature, the colour is much paler, 

 the body almost glabrous above, and not pilose as in T. saccata; 

 the head, sternum, and opercula ochraceous beneath and not very 

 dark castaneous, and the abdomen is narrower and more attenu- 

 ated [Distant]. 



This handsome insect with its much brighter colouration seems 

 to take the place in the Townsville district of T. saccata, which 

 does not extend beyond Brisbane, and is comparatively common. 



Genus Henicopsaltria, Stal.

Body oblong. Head wider than front of pronotum; front con- 

 vex, with a median longitudinal sulcus; apex of clypeus acumi- 

 nate; ocelli two, sometimes three, times more distant from the e3'es 

 than from each other, Pt^onotum narrower in front than behind, 

 front angles not covered by lateral part of head, often prominent; 

 lateral borders destitute of denticles. 2Ietasternuin not elevated, 

 destitute of a posterior process. Tegmina with basal area some- 

 what, rarely double, longer than broad; ulnar veins distant at base; 

 interior ulnar area distinctly broadened towards base. Wings 

 with six apical areas. Abdomen robust, the sides in the male 

 sometimes furnished with large sacs laterally as in Thopha; oper- 

 cula medium in size. Front femora spined below.
