Epichostis tympanias

Description

Epichostis tympanias is a moth in the Xyloryctidae family. It was described by Meyrick in 1908. It is found in India (Assam). The wingspan is 18–23 mm. The forewings are rather light fuscous, somewhat deeper in females. The costal edge, except towards the base, and veins towards the costa are more or less streaked with ferruginous-yellow, and the costal area in males variably suffused with light ochreous-yellowish. There are two large sharply marked black dorsal blotches, edged with pale yellowish, the first rounded-triangular, extending on the dorsum from the base to near two-fifths and reaching more than half across the wing, the second irregular-trapezoidal, reaching three-fourths across the wing and extending in the disc from before the middle to five-sixths, but more or less considerably narrowed towards the dorsum, the posterior edge obtusely prominent in the middle of the wing. There is an interrupted black terminal line. The hindwings in males are grey, in females dark grey.
