Alurnus nigripes is entirely red above, "with the exception of the 

 black scutellum, and occasionally a short longitudinal line on the 

 thorax of the same coloiu- ; its punctuation is coarser and larger than 

 in A. coccineus, which, in addition to the black legs, serves to distin- 

 guish it from the red variety of that insect ; it is also of larger size.
