of the Australian Pyralidina. 281 



Balanotis, Meyr. 

 Valves of male strong ; uncus moderately long. 



Balanotis hercophora, n. s. 

 5 , 25 mm. Head and palpi ochreous-yellow. Antennae grey. 

 Thorax ochreous-yellow ; a ring before anterior margin, a large 

 central spot, a small lateral spot, and another at extremity of 

 patagia, dark fuscous. Abdomen whitish ochreous, partially 

 suffused with yellow, with a large irregular dark fuscous spot on 

 side of each segment. Anterior legs dark fuscous (others broken). 

 Fore wings moderate, triangular, costa slightly arched, apex 

 rounded, hind margin rather obliquely I'ounded ; yellowish white, 

 veins and margins of dark markings yellow, markings dark 

 fuscous ; a spot on base of costa ; four transverse fasciae ; first 

 straight, moderately broad, near base ; second straight, from one- 

 third of costa to two-fifths of inner margin, outer edge with a 

 short projection above middle ; third from two-thirds of costa to 

 two-thirds of inner margin, irregiilar-edged, rather strongly 

 curved outwards in middle, rather sinuate beneath, united with 

 second by a rather broad streak along costa, and another along 

 inner margin ; fourth hind marginal, inner edge irregular ; a 

 transverse-elongate black discal spot, almost touching costal 

 border; ciha dark fuscous (imperfect). Hind wings yellow- 

 whitish, suffused with yellow towards costa and inner margin ; 

 a small cloudy fuscous spot in disc before and below middle ; a 

 dark fuscous fascia at two-thirds, and another along hind margin, 

 both as in fore wings, but former not reaching inner margin ; cilia 

 as in fore wings. 



A conspicuously distinct species, allied to B. didymalis, 

 with which it entirely agrees in structure (unless the 

 male presents differences) except that vein 6 of the fore 

 wings also rises out of 9 near base, whilst in B. didymalis 

 6 and 9 rise from a point ; not improbably this differ- 

 ence may not persist in the male. 



Port Darwin, North Australia ; one specimen. 



Balanotis didymalis, Walk. 



I have been enabled to examine the male ; the fore 

 wings have no glandular swelling beneath the costa ; the 

 antennae are evenly ciliated (|-). I do not think these 

 differences need involve generic separation. The genus 

 cannot be confused with any other structurally except
