Compare other Magicica species. Try to get photos of the abdomen or record audio. Brood X will have broad orange bands on abdomen (more orange than black). This species is larger than the other two species and the only one with the orange marking between the eye and the wing base. Because people tend to collect/document the largest cicadas they see, this species is probably over-sampled (R. Orr, pers. comm.). Song is also diagnostic.
