TINEIDiE. ONCOCEUA. 313 



Anterior wings of an ashy- or reddish-brown, faintly dotted or clouded with 

 dusky; with two large, somewhat trapeziform black spots on the disc, 

 placed longitudinally, and beyond the second an irregular very indistinct 

 and much curved fuscous streak, and on the extreme edge some irregular 

 wedge shaped fuscous spots; on the costa, towards the apex, are thiee or 

 four deep fuscous spots ; cilia ashy : posterior wings fuscous, immaculate ; 

 cilia white. 



Extremely variable in tint, and in the bulk and intensity of the dark blotches 

 on the anterior wings, the latter being in some cases very large and distinct, 

 in others small and nearly obliterated. 



In general somewhat rare, though greatly diffused; but in July 

 and August 1818 it abounded every where, being abundant in the 

 gardens and squares of the metropolis itself; also at Dover, in 

 Norfolk, Devonshire, &:c. 



Genus CCCLXV. — Oncocera* mihi. 



Palpi four ; maxillary minute ; labial elongate, slender, recurved, clothed with 

 shortish scales above and long ones below, the apical joint long and slender, 

 acute: viaxillce short. Antennoe rather long and slender in the males, with 

 an ovate mass of scales at the base, and pubescent to the apex, in the females 

 simple : head small : eyes rather large : thoi'ax siibovate, not crested : wings 

 convoluted during repose ; anterior elongate-triangular, subtruncate at the 

 apex ; the disc without fasciae, being of simple, but bright, colours, either 

 remotely spotted or longitudinally streaked ; posterior wings ample, much 

 folded ; cilia all short : body rather long and slender, with a small tuft at 

 the apex in the males, acute in the females : legs rather long. 



Oncocera differs from Phycita, with which genus the species have been 

 associated, not only by the variation in the form of the palpi, but in 

 being of a totally different habit : in the insects of the present genus 

 — the males of which, like those of Phycita, have a mass of scales at 

 the base of the antennae ; — the anterior wings are totally destitute of 

 the two, or more, pale transverse fasciae which adorn those of the genus 

 just referred to ; their colours approximate to, and the texture of the 

 wings resembles, that of Crambus, with which genus they have been 

 also associated.
