 space of about 400 yards in extent, on the coast of Deal." 



TitYPHiENA subsequa, W. V. Concerning the true sub- 

 sequa, Mr. Doubleday writes in the Zoologist for 1844, page 

 399 — " Mr. Bentley possesses two specimens of the species, 

 one captured by himself in Hampshire, the other from Mr. 

 Stone's Cabinet, probably taken in the same county. The 

 species is very likely to occur in the southern counties, as it 

 is not uncommon in the northern parts of France." Since 

 this was written, it has been repeatedly taken by sugaring in 

 the New Forest, and is now in most collections. The black 

 spot towards the apex of the costa of the anterior wings, as 

 in pronuba, at once distinguishes it from orbona. 



Opigena Fennica, Eversmann. " A single specimen 

 of this Noctua, hitherto unknown in Britain, and principally 

 found in Finland, has been taken in Derbyshire ;" this notice 

 by Mr. Doubleday appears in the Zoologist for 1850, page 

 2971. The specimen is in the collection of Mr. Allis. 

 Guenee retains this species in his genus Agrotis, but observes 

 that it has " un facies particulier." It is figured by Du- 

 ponchel and Herrich-Schaffer. 



Graphiphora ditrapezium, Bork., (Noctua ditra- 

 pezium, Doubl.) ; first recorded as British under the name 

 of tristigma by Mr. Stevens, Zoologist for 1846, page 1347 

 — " I fortunately possess a specimen of this distinct species, 

 the true Graphiphora tristigma of the Continent, which I 

 have had in my cabinet the last two years, and supposed it 

 only an extraordinary variety of triangulum, which it much 

 resembles ;" and he then proceeds to describe wherein it 

 differs from triangulum. At the August meeting of the 

 Entomological Society in 1852, "Mr. S. Stevens exhibited 

 Graphiphora ditrapezium, reared from a larva found at 

 Leith Hill, in Surrey." An old specimen has been detected 

 in the collection of the Entomological Society. The larva,
