into pustules, even near the apex the pustules being very much smaller and closer 
than in roseola. Its veiy much nai-rower prothoi'ax will at once distinguish it fi'om 
glauca., as well as the much less convexity of its form. From yi/garnetisis its 
different colour and the much more strongly produced (in a downward direction) 
humeral angles of its elytra render it very distinct. The width of its elytra is 
difficult to calculate exactly, because in both the specimens those organs are pai'tly 
displaced (as though for flight); as nearly as I can measure, however, their width 
is just about equal to the distance from their apex to a point slightly in front of 
the middle of the prosternum. This species is not easy to place exactly in the 
tabulation referred to above, because in distinguishing in the table roseola, glauca 
dL\\l\. yilgarjmisis I have availed myself of the fact that the first of those species has 
its elytral punctures exceptionally darkly coloured, while in the other two those 
punctures show scarcely any colouring; the present species, however, is intei'- 
mediate in this respect, one of the specimens having its elytral punctures evidently 
infuscate, the other scarcely so.

I do not find any difference between the male and female apart from the 
ordinary differences in the tarsi, etc., and in the male being somewhat smaller and 
proportionately shorter than the female. This species should be placed, in my 
opinion, near the beginning of Dr. Chapuis’ “ Groupe II.,” having the sides of its 
prothorax evenly arched and the front angles of the .same not mucronate, and its 
elyti-al punctures not running in lines and showing a slight tendency to leave
