CATALOGUE OF MOTHS. 117 



high land in the west of Durham. There Mr. Gardner found it 

 by pure accident. He had gathered fungi for breeding 

 Coleoptera, and much to his delight this rarity emerged. I do 

 not know what the fungus was, but it grew on alder in Upper 

 Teesdale. He has bred it several times since the first discovery. 

 In the Ent. Ann., for 1858, p. 104, Stainton wrote " A remark- 

 ably small specimen of this pretty species was taken by Mr. 

 "Wailes in July, on the stem of a birch tree. The larva will 

 probably be found in fungi on birches." No locality is 

 mentioned. 



20. T. corticella, Curt. 



Tinea corticella, Staint. Man., vol. ii., p. 291.

A local species of the occurrence of which I have no recent 

 record. It is given in the " Manual " as having been met with 

 at JS'ewcastle-on-Tyne, and the specimens may have been taken 

 by Mr. AVailes in IS^orth-West Durham. Mr. Backhouse took 

 it in Kepier Wood, near Durham. Neither Mr. Finlay nor Mr. 

 Maling appears to have met with it in Northumberland, nor Mr. 

 Sang in Durham, the above records being more than fifty years 

 old. The larva feeds in fungus growing on trees, but Mr. 

 Gardner, who collects fungus to 'hYeQ(\. picarella, does not appear 

 to have met with this species. I do not wish to throw any 

 doubt on these old records, but rather to induce others who 

 have the opportunity to try and rear corticella. 



21. T. parasitella, Hub, 



Tinea parasitella. Staint. Man., vol. ii., p. 291. 

 ,, ,, Meyr. Hdbk. Brit. Lep., p. 788. 



The larva of this insect also feeds on fungi, and Stainton adds 

 "rotten wood." The only notice of its occurrence is the "Ne" 

 of the " Manual." Wailes collected in the Derwent Valley and 

 in Castle Eden Dene, as well as at many places in Northum- 

 berland, but I do not know where this was taken — probably in 

 the north-west of Durham. It is a pity that no one collects 

 these small things there now.
