Mule: Expanse 58 mm. Length 38 mm. 



Head moderately large ; eyes dark brown above, sepia tint beneath ; 

 occiput vesicle and uj^per part of epistome dark brown ; lower part of

 or traversed by a strongly convex nervure; 1 row of cells between 5 and 

 5a, some of these occasionally divided ; stigma bright opaque yellow ; costa 

 brown or reddish brown outwardly ; a broad, blackish brown fascia crossing 

 both wings from the base as far out as the 2nd postnodal nervure in the

 surface ; tentaculte very small, the internal, slim, strongly curved hooks,
