submoniliform striga, heyond which tho ri>.>^t of the wing is deep fuscous, with an undulated white strirra 

 composed of approximating wedge-shaped spots ; in the margin itself is a series of minute, black, subtriano-ular 

 dots ; cilia pale ash ; posterior wings pure white. Female nearly of an uniform pale cinereous, with the stigmata 

 and costal spots nearly obsolete. 



Taken in July 1827, by W. Uaddon, Ksq., near Barnstaple, Devonshire. 



Note. — In :ul<iition to llic picrfJing S[ii-cics, tlic Noctiia riassa of Hiiljiier (Onipliiiihoia cr. Steplicns, nob.) is regarded by Boisduval as a 

 species of tile present genus. 



GRAPHIPHOKA, Ociisexheimer, HiinxER, Stephens. 



The species of this genus are distinguished from Agrotis, to which they are nearly allied, by havino- the 

 antennte simple (at least to the naked eye) in both sexes, or but sub-pectinated in the males. The i)alpi 

 extending beyond the head, nearly straight, and compressed laterally ; the second joint large and securiform, 

 spotted with black on the outside ; the third joint short, naked, and obtuse ; the thorax almost square, with a 

 small crest behind the collar, which is but slightly or not at all elevated ; the fore wings broad, rounded along 

 the apical margin, obtuse at the tip, and glossy, having tlie two ordinary stigmata distinct (the teliform one 

 being generally obsolete) and separated by black or brown s]iots. The caterpillars are cylindric, somevifhat 

 thickened behind, not being attenuated to the extremities, obscurely coloured, slightly velvety in texture, 

 gcncrallj' exhibiting two sub-dorsal rows of black dots, of which the two hindermost are most distinct, in which 

 respect they approach the Tripliccna'. They feed upon low jiiants, beneath the dead leaves of which they 

 conceal themselves during the day. The chrysalides are cylindric conic, and smooth, and buried at a greater or 

 less depth under ground, either without a distinct, or with a very slight cocoon of earth. 



In their habits, when arrived at the ])orfcct state, they closely approach the Agrotes ; flying with 

 great rapidity at night over the flowers, from wiiich they extract the sweets with their long spiral tongues. 

 By day they conceal themselves beneath the iurbage, or affix themselves stationary on walls and the trunks 

 of trees. 



The species of this genus, as here arranged, are distributed by Boisiluval into his genera Chersotis, Noctua, 

 and Spadotis.
