Xll PREFACE. 



Entomology not only presents a much wider field for discovery than 

 any other branch of Natural History, but in this country at least it 

 has a greater number of ardent and devoted students; hence the 

 amount of novelty is also greater : the principal additions occur in 

 Lepidoptera. Mr. Weaver has taken a Psyche in the New Forest, 

 pronounced by Mr. Stephens to be P. opacella of Herrick-Schseffer, 

 but unfortunately described as new (App. xcix) under the name of P. 

 Fenella. The species taken last year by Messrs. Ingall and S. Stevens 

 has been described under the name of Psyche reticella (App. xciv). 

 Mr. Doubleday records the capture of a single specimen of OpigenaFen- 

 nica. Mr. Stainton has taken a specimen of Orthosia ruticilla at Shef- 

 field. Mr. Doubleday describes four species, new not only to Britain 

 but to science : EupitheciapalustrariafApp. cv.) apparently of common 

 occurrence in Huntingdonshire : E. Callunaria (Id.) common on the 

 heaths of Scotland and the north of England : Hypenodes humidalis 

 (Id.) taken in Ireland in 1848, and subsequently by Messrs. Hodg- 

 kinson, Cooke, Greening, Cooper and others, apparently in the ut- 

 most profusion in Delamere Forest, Cheshire : Spilonota Rosaecolana 

 (App. cvi) previously described and figured by Duponchel under the 

 name of suffusana, which clearly belongs to another species : it does 

 not appear to be uncommon, but had previously been confounded with 

 a cognate species. Mr. Stephens has noticed the occurrence in this 

 country of Crambus Lythargyrellus, (Zool. 2958) that name having 

 been previously introduced into the British list in error : Mr. Stephens 

 is uncertain as to the locality of his unique specimen : the same dis- 

 tinguished entomologist also records the capture by Mr. Weaver, in 

 Scotland, of a pair of the Tinea ochraceella of Tengstrom : this in- 

 sect has hitherto only been found in ants' nests. Mr. Douglas has 

 described the following Microlepidoptera : Elachista occultella (Zool. 

 2806) found in May, 1848, flying above long grass under trees, in West 

 Wickham Wood, Kent : Grapholitha Weirana (Zool. 2806) found in 

 May, flying in sunshine round beech-trees at Mickleham, Surrey : 

 Ypsolophus palustrellus, (Zool. 2835) the locality of which is not re- 

 corded, but two examples of which have been examined, one in Mr. 

 Doubleday's the other in Mr. Allis's cabinet. Mr. Sircom has de-
