14. Second discal stigma transversely double 10. subaquilea. 



,, single, indistinct 14. flavifrontella. 



15. Forewings with dark fuscous terminal spots 



15. pseudospretella. 

 ,, without terminal spots . 16. fuscescens. 



1. A. grandis, Desv. 10-13 mm. Antennae with apex white. 

 Forewings orange, margined with dark fuscous except at base 

 of dorsum, more broadly on termen, forming a spot at base of 

 costa ; a transverse streak near base, and three longitudinal 

 streaks in disc bluish -silvery, blackish-edged; a pale yellow

 at ; a triangular yellow spot before tornus. Hindwings

Worcester, Stafford, North Wales, local ; Germany, Switzer- 

 land ; 5, 6. Larva in decayed wood ; 1 2-3. 



2. A. formosella, F. 10-13 mm. Forewings orange; a 

 subquadrate ferruginous spot on dorsum before middle, laterally 

 edged with white streaks, posterior produced obliquely to 

 middle of disc ; an oblique trapezoidal ferruginous blotch about

 attenuated on costa beyond middle, fifth large, irregular, 

 occupying termen and apex. Hindwings ovate-lanceolate, dark 

 fuscous. 



Lancashire (near Manchester), once taken in plenty, not 

 since 1829; not recorded elsewhere; 6. The species maybe 

 very local, and there is no necessity to suppose it extinct ; the 

 larva would probably feed in decayed wood.

 with dark fuscous. Forewings orange, towards margins more 

 ferruginous ; a narrow dark fuscous costal streak from base to
