Pseudochoreutes, SnelL, but structurally they differ con- 

 siderably from it. The two species described are readily 

 separated by the difference in the length of the labial 

 palpi, as well as in marking.

 fuscous, especially towards inner margin, sinuate-curved outwards 

 above middle ; hind marginal area somewhat suffused with 

 ochreous-brown ; a small double black spot on hind margin in

Var. «, 16 — 20 mm. More or less wholly suffused with fuscous, 

 but markings distinct.
