Ollanta modesta (Distant, 1881)
The image says Selymbria modesta, but the newest name of this cicada is Ollanta modesta.

Species description by W. L. Distant:

Body dull testaceous. Head with the frontal margin, area of the ocelli, and posterior margin of eyes fuscous. Pronotum with two central fuscous fasciae on anterior margin, and sometimes two smaller ones on posterior margin. Mesonotum with two large obconical central spots on anterior margin; on each side of these a longer and more obscure obconical fascia, and a transverse fascia on disk, preceded by two small spots, fuscous. Basal margins of scutellum and abdominal segments fuscous. Body beneath paler; anterior margin of head and inner margin of eyes black. Tegmina pale hyaline; neuration ochraceous or dull testaceous (sometimes with the basal half much paler); transverse veins at the base of second and third apical areas, and a submarginal row of spots on longitudinal veins of first, second, and third apical areas fuscous. Wings pale hyaline, with the nervures ochraceous or testaceous.

Head, including eyes, equal in breadth to base of pronotum; face with a very deep central longitudinal sulcation, and strongly and transversely striate. Opercula pale, broad, not passing base of first abdominal segment, and narrowed but not meeting interiorly.

Long. 16 millim., exp. tegm. 57 millim.

This is the only Central- American species of the genus with which I am acquainted. It varies somewhat in the markings of the pronotum and mesonotum.
