166 HAUSTELLATA. — LEPIDOPTERA. 



bent, the second nearly as long again, more slender than the first, a little 

 attenuated at the apex; terminal linear, very slender, shghtly acuminated: 

 maxillw longer than the antennse. Antennae short, slender in the females, 

 ciliated internally in the males : head small, with a crest between the antenna? : 

 eyes rather prominent, naked : thorax stout, with an anterior and posterior 

 crest : abdomen slightly depressed, with a carina in the male : wings incum- 

 bent, faintly denticulate: legs short, rather stout. Larva naked, with the 

 anal segment a little elevated : pupa folliculated, with a single spine at the 

 apex. 



With this genus Ochsenheimer and Treitschke unite Phalsena 

 Maura of Linnaeus, than which nothing can be more unnatural, 

 their only resemblance consisting in the dinginess of-tlieir colours : 

 I have therefore divided them, as no possible advantage can be 

 gained by their union. Nsenia may be readily known by the pe- 

 culiar bifid appearance of the apex of the palpi, arising from the 

 elongation of the scales — thereby remotely resembling those of 

 Triphsena — combined with the highly crested thorax, dingy, re- 

 ticulated, and subcrenated wings ; exclusively of the structure of 

 the palpi.

Head and thorax fuscous ; the latter with some ash-coloured and black atoms 

 on the crest : anterior wings fuscous, with the nervures pale hoary or whitish ; 

 an irregular striga of whitish and black patches at the base, a slightly waved 

 interrupted whitish transverse striga, margined on each side with black before 

 the anterior stigma, then a third striga, arising between two black spots on 

 the costa, opposite the posterior stigma, suddenly bent outwards at its origin, 

 terminating behind the middle of the inner margin, and bordered on each 

 side with black lunules ; beyond this, near the posterior margin, is a fourth 

 narrow undulated one, suddenly angulated near the costa, and bounded on the 

 inner edge with some irregular black spots ; on the margin of the wing itself 

 is a row of black trigonate spots ; a quadrate spot between the stigmata, and 

 an oval one behind the posterior black : stigmata cinereous with pale margins ; 

 with sometimes a third indistinct one, as in most of the Agrotes : posterior 

 wings plain fuscous, with paler cilia. 



This species varies considerably ; in some examples the strigae are merely indi- 

 cated by their dusky margins, while in others they are nearly white. 



Caterpillar griseous, the sides dusky, with three pale streaks : it feeds on the 

 Nettle, Houndstongue, Willow, &c.: the pupa is brown, enclosed in a web; 

 and the imago is produced towards the end of June.
