species) is very variable both in size and markings. I have three 
examples—two from my own cabinet (from the Chevrolat and 
La Ferté collections) and one from Mr. Baly’s ; and each of these 
three differs materially from the other two. The circular black 
markings in one are insular, in the others are more or less con- 
fluent, and in none are they disposed according to any arrange- 
ment common to either of the other examples. I have no doubt 
that they constitute one species, although obviously | am unable 
to record its typical pattern or its limits. 
Chevrolat’s example is labelled with the name “ nzgrosignata, 
Bohn.” : I have adopted it, although I am unable to discover 
any published description of M. Boheman’s of the species.

This species can only be confounded with the following, 
P. subcruciata, from which it is readily separated by its imma- 
culate thorax and by the well-defined and distinct stria-like 
punctures on the elytra. 
From South Africa; but IT am uncertain of the exact district.
