LEPIDOPTERA. 



Notes on New and Rare British Lepidoptera 

 (excepting Tineina) in 1870. 



By H. Guard Knaggs. M.D., F.L.S. 



Once more the time for reckoning up the work of the past 

 season has come round, and on me again devolves the plea- 

 sant task of ofatherino; totjether, siftino; and sorting: into 

 something like order, the discoveries and contributions to- 

 wards a knowledge of our moth fauna, accumulated since the 

 publication of our last little volume. 



The year 1870, although it may not have produced any- 

 thing very startling in the way of additions to our lists, has 

 been a very average one. We have certainly no new butterfly 

 nor sphinx, nor can we boast a new bombyx, at least only 

 half a Psyche, namely, " the better half" of Fumea reti- 

 cella, — but we have a new Plusia, though it is somewhat 

 unsatisfactory that a single example only has been secured — 

 not but that P. ni, which was discovered two years ago, is 

 in the same predicament— but then ni is an European species, 

 whereas unfortunately this one is not ; this, however, will be 

 discussed further on. We have two new Geometrae, both in 

 the genus Acidalia, which, with four new knothorns, two 

 new tortrices and a new plume, will be sufficient to give our 

 old heads something to think about. The following is our 

 list of discoveries : — 



1. Fmnea retkella, Newman, ? . 



2. Plusia verticillata, Guenee.
