I have before me several examples of Macleay's iusect, and am 
inclined to think them distinct from plagiata though undoubtedly 
the lateral margin (of the spot) which runs hindward as a straight 
line parallel to the suture to join the lateral margin of the elytra, 
reaching it at a very short distance from the apex (of the elytra). 
In plagiata but not in carinata the lateral margin of the elytra. 
is of a red colour distinctly brighter than the “colour of other 
parts of the surface, and the pronotum of carinata is evidently 
more gibbous than that of plagiata with the central longitudinal 
line considerably more dade impressed.
