In his recent paper [Pr. Lin. Soc. NSW. XXXII. 47-68 (1907)] 

 Meyrick has removed the groups of Gracilaria and Zelleria from 

 the Tineiclae to the Plutellidae, assigning now " more importance to 

 the smooth posterior tibiae which are a normal attribute of those 

 two groups, than to the rough head which is a frequent character- 

 istic. Moreover, whilst folded maxillary palpi are peculiarly 

 characteristic of the Tineiclae, the simple porrected maxillary 

 palpi of the Gracilaria group are so similar to those of the Plutella 

 group, and so diflerent from those of any other Tineina, that they 

 would seem to indicate real affinity." He concludes from his 

 study of the Gracilaria group that " Coriscium Z. cannot be 

 maintained as a distinct or natural genus, the scaling of the palpi 

 being subject to much variation, and not according with true 

 affinity. On the other hand," he has " found it practicable to use 

 the scaling of the legs to break up the whole of the species thus 

 thrown together into four groups which are both natural and 

 strictly definable, and since the number of species known is 

 already very large and destined to be much larger," he has 

 " thought it conducive to clearness to establish them as genera." 

 Cyphosticha Meyr. and Conopomorpha Meyr., having " Posterior 

 tibiae with bristly hairs above," are separated from Gracilaria 

 Hw, and Macarostola Meyr., with "Posterior tibiae smooth- 

 scaled." Dialectica Wlsm. is sunk as a synonym of Conopomorpha 

 Meyr. ; but hrongniardellum F. also has " Posterior tibiae bristly 

 above [Meyr. HB. Br. Lp. 749 (1894)], for which reason Wallen- 

 gren removed it from Coriscium Z., making it the type of 

 Acrocercops Wlgn. (1881), described as having " Tibiae postice 

 setosae," and, consequently, Conopomorpha must also sink as a 

 synonym.
