24 pyralidid;e. 



Pyrausta ostrinalis ?, Hb. 



jmnkcalis, Haw. 



(Plate 2. fig. 13.) 



Loc. Plymouth, Bristol, Huddersfield, Richmond 

 (York.), Scarborough, Biddleston, Irelaud, Scotland? 



Occurs in June and again in August ; it frequents 

 many of the same localities as purpuralis, of which 

 it is probably only a variety. Although the ex- 

 treme forms of purpuralis and ostrinalis are distinct 

 enough, yet all tlie intormcdiato grades occur commonly, 

 and it is impossible to say where purpuralis ends and 

 ostrinalis begins. The late Professor Zeller had a large 

 series in which some specimens were laheWed purpuralis, 

 others ostrinalis, evidently not thinking it wise to 

 separate them. 



The extreme specimens of ostrinalis differ from pur- 

 puralis in the pale yellow baud not being divided into 

 spots. 



Bhodaria sanguinalis, L. 



cnientalin, Scriba. 



(Plate 3. fig. 1.) 



Loc. Troon (Ayrshire) ?, Wallasey sandhills, llhyl, 

 Galway, Cheshire sandhills, New Brighton. 



Occurs in May (?) and August on sandhills. 



Some specimens are much suffused with pink. The 

 larva is red with a white dorsal line ; it feeds on 

 Thymus serpyllum in a web, devouring the flowers by 

 preference.
