The type of this genus is Tlicreira nessiis (Drury), a large 

 East Indian moth, with the body very stout, as well as long 

 and tapering ; the fore-wings are very long, and slightly 

 hooked at the tip, and the insect shows some resemblance 

 to the American genera PJiilaiupelus and Dupo in form and 

 colouring. 



" Differs from Chcvjvcainpa in having the basal joints of the 

 palpi hollowed out, with an orifice towards the exterior, beset 

 with (? sensory) setse." {Hampson.)
