236 Mr. E. Meyrick on Pyralidina from 



variation in the extent of the yellow suffusion, tending 

 to produce local forms, which nevertheless I do not find 

 constant. Generally there is a tendency in Indo- 

 Malayan and Australian forms to show a yellow sub- 

 marginal streak, which is usually absent in American 

 specimens ; but the difference seems unreliable. 



Myriostephes achcealis, Walk. 



Botys achcealis {achceusalis) , Walk., 1007. 



S ? , 25 — 27 mm. Head orange, lower part of face dark fuscous. 

 Palpi dark fuscous, lower longitudinal half orange. Antennae 

 whitish-ochreous, basal joint orange with a black dot, ciliations of 

 male 1A. Thorax orange, shoulders narrowly black. Abdomen 

 orange, with a black band at three-fourths. Legs pale orange, 

 anterior tibiae banded with black. Fore wings very elongate- 

 triangular, costa posteriorly moderately arched, apex obtuse, hind 

 margin obliquely rounded ; orange ; markings blackish, slightly 

 bluish-tinged ; a moderate streak along costa from base to two- 

 thirds ; a rather narrow straight fascia from two-fifths of costa to 

 two-fifths of inner margin, beneath costal streak dilated to contain 

 a dot of ground colour ; a rather narrow fascia from three-fifths of 

 costa to anal angle, much dilated beneath, and confluent with an 

 irregular moderate hind-marginal fascia; cilia dark grey. Hind 

 wings orange ; a moderate somewhat irregular blackish hind- 

 marginal fascia, narrowed beneath ; cilia dark grey. 



Sydney, New South Wales ; several specimens in 

 February and March (coll. Macleay). Rather a dis- 

 cordant species ; but I find the resemblance to 

 Metallarcha apparently superficial only. 



Deuterarcha, Meyr. 

 Deuterarcha xanthomela, Meyr. 

 Also from Toowoomba, Queensland, in December. 

 Emprepes insignis, Butl., Trans. Ent. Soc. Lond., 1886, 

 431, is a synonym of this. 



Metallarcha, Meyr. 



Metallarcha tetraplaca, n. s. 



g o, l'j — 22 nun. Head yellow, frontal projection flattened- 



conical. Palpi blackish, lower longitudinal half yellow. Antennae 



pale yellowish. Thorax yellow, shoulders dark fuscous. Abdomen
