DIRCENNA. 119 



Genus X. DIRCENNA. 



Ceratinia, Oleria, Hiibn. 

 Heliconia God'. 



Head broad ; the forehead and face clothed with long hairs. 



Eyes oval, prominent. 



Maxillae moderately stout, about as long as the thorax. 



Labial Palpi scarcely rising above the forehead, rather stout, scaly, and, in front especially, 

 clothed with long hair, the dorsal tuft distinct. First joint stout, subcylindric, rather 

 thickest at the base, curved, fully two thirds the length of the second, which is nearly 

 cylindric, very slightly curved ; the apex obliquely truncate, slightly rounded internally ; third 

 joint elongate, at least two fifths the length of the second, broadest at the base, where it is 

 rounded, tapering towards the apex. 



Antenna? rather more than two thirds the length of the body, gradually enlarging into an elongate 

 club; the basal joints elongate, those of the club shorter and more distinct; the last rather 

 pointed. 

 Thorax rather stout. 



Anterior Wings diaphanous, elongate, triangular, rounded at the apex ; the anterior margin 

 rounded, nearly twice the length of the outer, which is very nearly straight between the first 

 discoidal nervule and the anal angle ; inner margin very little longer than the outer, rather 

 deeply emarginate in the males, less so in the females. Costal nervure terminating nearly 

 opposite the end of the cell. Subcostal nervure emitting its first nervule at some distance 

 before the end of the cell ; the second about at an equal distance beyond the cell ; the third 

 about equally distant from the second and fourth ; the latter terminating nearly at the apex ; the 

 fifth at a short distance below the apex. Upper disco-cellular nervule wanting. Middle 

 disco-cellular directed obliquely inwards ; the lower one sinuous, directed obliquely outwards. 

 Third median nervule bent at an obtuse angle, where it is joined by the lower discoidal nervule. 

 Internal nervure slender, running into the submedian. 



Posterior Wings diaphanous, obovate ; the anterior margin in the males nearly straight at the base. 

 Precostal nervule mostly simple, curved backwards. Costal and subcostal nervures united as 

 far as the origin of the precostal, running nearly parallel and close to one another, the latter 

 dividing into its two nervules not far from the outer angle ; the first nervule being the shorter, 

 and reaching the costa nearer to the termination of the costal nervure than to the outer angle ;
