The subject of Vol. XIII. o£ the ' Catalogue of Moths ' is the 

 classification of the remainder of the Noctuid subfamily Gatocalince 

 and the subfamilies Momince and Pliytometrince. 



The GatocaliiKB are represented in the present voltime by 

 44 genera and 379 species, making a total of 107 genera and 

 1022 species for the subfamily. 



The Momince, with 11 genera and 74 species, are characterized 

 by the eyes being hairy and vein 5 of the hind wing being fully 

 developed and arising from close to the lower angle of cell ; that 

 they are ratber closely related to the only other Noctuid subfamily 

 Avitb hairy eyes — the HadenineB — seems probable, but the exact 

 relationship between the Trifid and Quadrifid subfamilies of 

 Noctuidce is still rather obscure. 



The PhytometrincB, with 15 genera and 226 species, are 

 similar, but the eyes are smooth and are overhung by bristly cilia ; 

 the tibiae are sometimes spined, but they do not appear to be at 

 all closely related either to the Gatocalince, which subfamily is 

 characterized by having spiny tibiae in the Quadrifid series, or to 

 the Agroiincc of the Trifid series.
