 CLEVELAND LEPIDOPTERA IN' 1902. 



By T. Ashtox Lofthouse, F.E.S. 



* Denotes Species recorded in our Proceedings for first time. 



The weather conditions prevailing this year were not at all 

 favourable to insect life. Early spring insects were out fairly well to 

 time and fairly numerous, the weather being a little more favourable 

 then than later ; May, which is generally cold and Avet, was 

 much colder and wetter even than usual, and in the whole of the 

 month there was scarcely one fine day. The summer and autumn 

 months, with the exception of a fortnight in June, were extremely 

 cold and sunless throughout, with the result that moths generally 

 were very scarce, and practically nothing occurred at sugar at any 

 time. Many species put in a notably late appearance, and then 

 only sparingly. Other species, generally taken, were not even 

 noticed at all. 



^Ir. Sachse sent a list from which the principal species are 

 noted lielow. With reference to the season, he says that " it was 

 a most unpropitious one, the weather being either wet or cold." 

 Between August r2th and September 10th he was on the 

 Continent, and therefore did not do any collecting in England 

 during that period. 



As an example of the late occurrence of many species, I may 

 mention the following : — Zyijirna Jilippwluhr fairly fresh on 

 August lOtli at Acklam ; Bryopliila perki, fresh out at Danby on 

 August 9th ; Cerif/o niafura at sugar on August 22nd ; Tajnnosfo/a 

 elyiid l)red August 26th ; Runiia luteokifa fresh, and Venusia 

 ca)i/I)/-{caria at Kildale on August 30th ; Hepialus syldnus on 

 August 3 1 St. and many other late occurrences could be instanced, 

 but the above will give a better idea to those who are acquainted 

 Avith the usual time of appearance of the species named, as to the 

 extraordinary character of the season. 



Diurni. Tlwla ruJn. — Xoticed at Eston on May 24th. 



Nocturni. Arheronf/a atropo><. — A specimen emerged in Mr. 

 Clayton's greenhouse on March 16th, from larca' found at 

 Kildale (W. Sachse). 



Nola (■ucullatella. — Several bred from larcaj beaten off white- 

 thorn at Eston (T. Belk).
