scobinated, the outer pair terminating in a sharply 

 emarginate hook, the hinder pair are broad and rounded. 

 The Columns are united to the tegumen by a buttress, 

 which opens out into an ovate lobe ; the vesica has a 

 strong spicule. 



Ridens. From C. H. Walker. 

 The Harpe is peaked; the clasper is more developed and 

 becomes a straight column ; in the centre of the sacculus 

 is a large flap, similar to that found on several of the 

 Cymatophora ; the uncus is bifurcate, and appears to work 

 laterally ; there is also an indication of a scaphium ; the 

 i^doeagus terminates in two strong hooks of uneven length, 

 curved inwards; the vesica has a small scobinated process. 



The Noetuidae now start with a long run, in 

 which the uncus consists of a single hook, with the 

 exception of two species, Xanthia silago and Miselia 

 oxyacanthcE, in which it is bifurcate. 



The Bpyophilidae are strongly generic. 



Bpyophila glandifera ; mupalis. From C. H. 

 Walker. 



The harpes are rounded, widening at the apex ; the 

 clasper consists of an elbowed hook ; the uncus is tongue 

 shaped ; the vesica has a strong cornutus. 



Impap. Pencils absent. 



The harpes are rounded, wider at the apex ; clasper an 

 elbowed hook ; uncus tongue shaped ; vesica has a large 

 and small cornutus. 



PePla. From George Harker. Pencils absent. 



Harpe rounded not wider at the apex ; clasper a column ; 

 uncus tongue shaped ; vesica with scobinated process. 



Moma opion. 



Harpe rounded emarginate at the anal angle, producing 

 a pollex ; clasper broad at the base tapers to a point ; 

 uncus simple with curved point; vesica with small bunch 

 of cornuti, and rosette of short teeth.
