the description of which in the main it very well agrees. The. 
only discordance is in the character given to the posterior an- 
gles of the thorax, which he calls acute. He quotes as synony- 
mous Tritoma dubia of Fabricius, and I have therefore inserted 
this reference; but Fabricius’s description is too brief to give 
certainty as to the identity of his species with ours. Certainly | 
C. agilis of Panzer, which Panzer calls C. agilis Fab., is a very 
different insect; belonging to the last section of this monograph, 
only 14 line long, with antennz shorter than the thorax. 
Latreille's description very well suits the flavo-testaceous im- 
mature variety, if we suppose, as is most probable, that the male 
is furnished with toothed hind trochanters, and that this was the 
sex he had before him. He synonyms with his species, but in 
doubt, Panzer's Helops fuscus 18. 1. and there is certainly some 
resemblance ; but the latter is figured with the basal margin of the 
thorax sinuate on each side; “Which will by no means. apply to
