 to 4,000 feet. 



The characters given as differentiating this species from others 

 of the genus are shortness of the first joint of antennae, the bright 

 red colour of the apex and inner portion of cuneus, the luteous 

 and erect character of the scutellar horn, together with small size 

 of the clavate head relatively to that of the stalk in both 

 male and female, and the markings on the pronotum of the 

 female.
