short digitus ; clasper with large round mouth ; ampulla 

 long, curved and tapered ; uncus broad at the tip ; 

 sedceagus dentated at the orifice ; vesica with scobinated 

 process and short cornutus ; the juxta is very elaborate, 

 from a squamose collar there arise laterally, two long 

 elbowed arms, deeply scobinated. 



The Orthosias are a curiously separated group. 



The elaborate and highly developed uncus of macilenta, 

 being worthy of attention, the long curved clasper of lota, 

 making a good connecting link to the Anchocelias. 



Orthosia suspecta. 



Harpe peaked, with corona, cucullus divided and spinose ; 

 clasper curved ; ampulla below the cucullus, small ; clavus 

 rounded, studded with small spines ; uncus slender ; 

 vesica with short cornutus ; juxta weak. 



Upsilon. Pencils present. 



Harpe peaked, almost trigonate, with corona ; cucullus 

 spinose and divided ; clasper strong, opening into a round 

 flattened plate with serrated edges ; ampulla elbowed, and 

 strong ; uncus tongue shaped, emarginate laterally ; vesica 

 with strong cornutus ; juxta doubly peaked, strong. 



Macilenta. From S. J. Capper. 



Harpe without corona, cucullus not divided, outer tip 

 longest ; clasper with curled tip ; ampulla extends to 

 centre of cucullus, the head being a rounded plate ; clavus 

 produced and lobed. It is almost imposible to describe 

 the complicated uncus, nor does the figure give any idea 

 of the extraordinary structure ; vesica with a long and 

 short cornutus, and a bunch of teeth ; juxta weak. 



Lota. With pencils. 



Harpe pointed, without corona ; cucullus not divided ; 

 clasper long and very curved, typical of this group ; 

 ampulla extends to the centre of the cucullus, where it 

 produces a sharp hook ; clavus rounded ; uncus sickle
