Macarinae. 



A well marked group, but a difficult one to locate; the large 

 sized signum, discoid and stellate, shows close relationship 

 to Ennomince, Bistonince, and some HybernincB. 



Carbonaria, Cl. and limbaria, F. must be included; 

 each of these species is closely allied to the other species 

 which we have included and possibly forms a subgenus. 

 Carbonaria has the distinctive uncus and the octavals, but 

 lacks the peculiar pointed form of sedceagus. Limbaria 

 has the peculiar pointed aedoeagus, but the cornuti are 

 different and it lacks the distinctive uncus and octavals. 



General description : Valvula weak, much reduced; 

 costa extended; sacculus extended set with more or less 

 than three papillae, first at the junction of the costa and 

 valva, second near the distal end of the sacculus, third on 

 the inner edge of the sacculus. Uncus has a pair of stout 

 spines dorsally at the apex. Gnathos pointed, strong. 

 .ZEdoeagus pointed. Cornuti rounded patch of overlapping 

 scobinations. Eighth sternite cleft, forming octavals. 



Ostium is peculiar, possessing a hinged lid which 

 completely closes the orifice, the operculum. In the 

 plate containing clathrata we give a drawing showing the 

 ostium open and closed. The signum is always discoid, 

 stellate, generally of large size. In clathrata this varies 

 considerably. 



Some of the characters appear to connect this group 

 with the Abraxintf, e.g. the rose thorn sedoeagus of 

 clathrata, and the gnathos of limbaria. 



Macaria carbonaria, Clerck., L. 33 



Valvula small; first papilla only. ^Edceagus stout, dentate 

 above. Cornutus absent. Saccus rounded. Octavals 

 cleft, shallow. 



Ostium weak. Signum discoid, obtusely serrated and 

 spined.
