NOCtUlDJ*:. — POLIA. 27 



subquadrate white spot, and between the latter and the hinder margin is an 

 undated white streak, and on the hinder margin itself is a slender inter- 

 rupted dusky line : ciha white, spotted with black : posterior wings yeUowish- 

 brown, with a dusky fimbria^ and two whitish spots towards the inner 

 angle. 



This beautiful and cotispicuous species is also unique in the 

 British Museum ; the specimen in the collection of that establish- 

 ment having been taken by Mr. Bydder, on a gate near Bircii- 

 wood, I believe, in June, 1816 : a fact which plainly shows the 

 extreme locality, or uncertain appearance, of particular species, as 

 the neighbourhood where it was captured has been long celebrated 

 for the richness of its entomological treasures, and has been for 

 many years most diligently explored. 



Genus CXXI. — Polia, Huhner. 



Palpi porrected obliquely, the basal joints densely clothed with elongate scales^ 

 the terminal exposed and sUghtly squamose, basal joint about half the length 

 of the second, a little bent; second sUghtly attenuated, obliquely truncate at 

 the apex , terminal compressed, ovate, acute : maxillw as long as the antennee. 

 AntennoE simple, pubescent beneath, sometimes shghtly produced, with pecti- 

 nated lobes in the males; in general each joint producing a bristle: head 

 clothed with short scales : eyes globose, sometimes pubescent : thorax stcut, 

 slightly crested: abdomen rather long, stout, sometimes with tufts on the 

 back, the apex obtuse in the females, with a small tuft in the males : wings 

 deflexed during repose; anterior elongate sublanceolate, the hinder margin 

 crenulated, posterior shghtly denticulated. 



The insects of this genus are amongst the largest of the indi- 

 genous Noctuidse, but the genus, as it at present stands, is evi- 

 dently most artificial, as may be readily seen by an inspection of 

 the two accompanying figures of Po« polyraita and templi; the 

 former insect resembling the Miselise, and the latter apparently 

 closely approximating to the first group of Graphiphora : the six 

 first species are clearly congenerous ; but yet notwithstanding Po. 

 tincta has the eyes naked, whereas in the rest they are pubescent : 

 the species after Po. templi are very discordant, but as their cha- 

 racters appear to resemble those of the true Polise more than those 

 of any other group, I have placed them at the end of this genus : 

 the last species, Po. Chi, in its perfect state has considerable 

 affinity to the Apatelse ; but its larva is widely different
