NOCTUID.E. EREMOBIA. 95 



crested behind : abdomen moderate, gradually attenuated to the apex, which 

 is slightly tufted; its back carinated, with a row of short, scaly, tufts; wings 

 entire, deflexed during repose ; anterior elongate-triangular, with the hinder 

 margin a Uttle produced in the middle; cilia very long; j^osterior ovate- 

 triangular; cilia ^oxt: /e^5 rather short ; anterior ^/Z>2ce greatly abbreviated; 

 posterior flattened, broad, with a lateral tuft of hairs. Caterpillar slightly 

 hairy : pupa rather slender. 



The only indigenous species of this genus has hitherto been 

 associated with Xanthia, with which it appears solely to agree in 

 its flavescent or rather ochraceous colour, its habit, period of flight, 

 and locality being totally different from those of the genus just 

 mentioned. Like the Plusise, and kindred genera, the Eremobise 

 fly by day, and again in the twilight, while the Xanthiee repose 

 during the former period : they frequent exposed heathy downs, 

 and appear in the beginning of summer. From Xanthia this genus 

 may be known by the elongation of the cilia on the anterior wings, 

 and by the rotundity of the hinder margin of the latter ; the dis- 

 similar proportions of the palpi, and by the form of the latter ; by 

 which latter characters it may be distinguished from Abrostola and 

 Plusia, exclusively of its obscurely crested thorax.

Head, thorax, and abdomen, yellowish-white, or ochraceous, with brownish 

 clouds on the two former; anterior wings varied with ochraceous and white, 

 or hoary, with a small fuscous dot at the base, then a subquadrate brownish 

 fascia, followed by an irregular broken fuscous band, edged with white a 

 little before the middle, and towards the hinder margin by an oblique paler 

 band, bearing a black streak about its middle, and a few dusky clouds 

 towards the inner margin of the wing; near the posterior margin is an 

 undulated whitish striga, and on the margin itself is a row of trigonate 

 black spots; cilia ochraceous- white, interrupted with cinereous: posterior 

 wings brownish, or cinereous, with a dusky fimbria, the latter separated 

 from the colour of the base by an undulated transverse ochraceous stigma : 

 cilia white, with a few cinereous clouds at the base. 



The Phytometra bifasciosa of Haworth is a variety of this species, or rather an 

 old example, with the colours a Uttle suffused : the original in Mr. Swainson's 

 cabinet. 



Caterpillar pale-yellow, with a brighter yellow lateral streak, on which are some 

 small dots, with fine hairs:— it feeds on tritici:— the imago appears about 

 July.
