HS LEl'IDOPTERA. 



1873, the late Mr. H. T. Stainton foretold the probable 

 discover}^ of this species here, and narrated how, on the 

 shores of the Baltic, the larva-tubes became often exposed 

 through the blowing away of the sand ; so that the fine 

 pupa became the ready prey of birds. 



G. H. turbidana, Tr. — Expanse f to | inch (18-22 

 mm.). Fore wings short and rather broad, olive-brown 

 thickly dotted with dark brown ; sometimes having a faint 

 indication of a paler roughly formed dorsal blotch. 



Antennse dark brown ; palpi and head dull ochreous- 

 brown ; thorax and abdomen dull umbreous. Fore wings 

 only moderately broad; costa folded and Hatly arched, apex 

 bluntly angulated; dull pale olive-brown rippled and dusted 

 all over with umbreous streaks, though less so toward the 

 base ; costa regularly streaked with olive-brown ; on the 

 dorsal margin are two very faint erect olive-brown streaks, 

 shaded outwardly and indicating a faint dorsal blotch ; cilia 

 olive-brown. Female similar, but larger and darker, and 

 devoid of the costal fold. 



Underside of the fore wings leaden-brown ; of the hind 

 wings leaden-white. 



On the wing from the end of May till July. 



Larva undescribed. It is believed to live through the 

 winter, and till May, in the stems and roots of PcUi.utta 

 rahjaris (butter-bur). 



This is one of our most local species, and one with which 

 I have no living acquaintance. More than half a century 

 ago my lamented friend Mr. Staintou paid a visit to Chud- 

 leigh, Devonshire, and near there, under Haldon Hill, he 

 found this species— which he called the hippopotamus tortrix, 

 because it is " large, brown, moderately ugly, and sleeps its 

 time away in marshy places on the banks of i^ivers." He 

 found specimens sitting on the leaves of butter-bur in the
