peculiar; the space round the scutellum is altuDst puiictureless 

 ^nd strongly nitid. The scutellum itself is scarcely visible. The 

 upper three spinules on the hind tibiae are very small.

 Another close ally of T. melburnius, Mars. It is distinctly of 

 narrower and slighter form than that insect, but I cannot 

 specify any other well defined difference apart from the sexual 

 <3haracter3 in the pygidium of one sex. In melbumiics the ine- 

 quality on that segment is caused by the apical one third of the 

 surface being on a different plane from that of the basal portion, 

 — -a slightly lower plane, — and the transition from the one plane 

 to the other being sudden there is a perfectly distinct (though not 

 sharply marked except in the middle) transverse line of demar- 

 •cation, which is more or less angular (the angle pointing hind- 

 ward) in the middle ; the portion on the lower plane is strongly 

 rugulose. In sorellense the same sex has practically no line of 

 demarcation between the smooth and rugulose puncturation of 

 the pygidium but the rugulosely punctured surface is widely and 

 very distinctly (though scarcely deeply) concave down its middle, 

 the concavity being non-existent in melburnius.
