its mouth after working it up iu a pellet. The bee had either forgotten to 

 lay its egg, or the egg had died ; it does not matter to us much which ; but 

 it has enabled me to state that this bee does collect pollen, like almost and 

 perhaps all other constructive bees." — Page 70. 



I may explain here that Collates and Prosopis (Hylseus) are the 

 two genera of bees that have obtuse instead of acute tongues, and 

 are " the only two that plaster their nests with a peculiar gold- 

 beater-skin-like substance, for which their tongues are admirably 

 adapted." 



A word on Mr. Barrett's paper. It may seem an easy thing to 

 take Doubleday's 'Synonymic List' into the woods and lanes, to 

 tick oflf with a pencil every butterfly or moth observed, to repeat 

 the same process week after week, and even month after month, 

 for four years, and finally, when nothing new turns up, to make a 

 catalogue of all the species so ticked off and send it to the printer ; 

 but really a great deal of labour, patience, perseverance and know- 

 ledge are involved in the task, and Mr. Barrett has brought all 

 these qualifications to his assistance. 



There are comparatively few Lepidoptera peculiar to Norfolk; 

 hence although this Catalogue contains a most ample list of species 

 and localities, it has no absorbing general interest, and serves 

 rather to illustrate the industry of the writer, which is most un- 

 questionable, than to extend our knowledge of the science : this 

 observation is by no means peculiarly applicable to Barrett's list; 

 it applies with equal and indeed with greater force to other similar 

 lists which have appeared in all our Natural-History periodicals. 



I observe that many previous errors and misstatements are 

 repeated, solely for the purpose of contradicting and condemning 

 them. Thus Chortobius Davus, Thecla Spini, Polyomraatus Dispar, 

 Arcturus Sparshallii and Eutricha Pini are introduced, although 

 Mr. Barrett is perfectly aware, and states explicitly, they have no 

 place in the Norfolk Fauna. There is no misrepresentation, but 

 rather supererogation in this unnecessary detail. 



There are apparently six species confined exclusively to Norfolk, 

 so far as the British Islands are concerned ; these are Lithosia 

 muscerda, Nonagria brevilinea, Crambus paludellus, and Sericoris 

 Doubledayana, confined to the fens; Crambus fascelinellus, in- 

 habiting the sandy denes at Yarmouth ; and Nothris verbascella, 

 attached to the very local mullein {Verbasciun floccosum), which 

 grows so abundantly around Norwich.
