Valva curved along the cost a; deeply indent below the 



cucullus; socii pads flattened, not free. iEdceagus 



pedunculate, coarsely scobinate, vesica with two long 

 cornuti. 



Ovipositor flattened. Ostium protruding cup-form; 

 ductus bursa wide, conate; signum pilleate. 



Genus 12. Epiblema, Hb. type foenella, L. 



This genus shows roughly the same Eorm of genitalia. The 

 constancy of Form of the valva makes description very 

 difficult, if not impossible. Fortunately in many 

 cases (lie wing parts are so distinct that it is not 

 necessary to refer doubtfuls to the examination of the 

 genitalia. We have tried to point out the distinguishing 

 feature of each, but reference to the figure is almost 

 imperative. 



The absence of the two spines at the orifice of the 

 Edoeagus separates this group from the preceding one. 



Valva with well marked cucullus. Uncus atrophied: 

 socii drooping. iEdoeagus on a peduncle, short, pointed; 

 cornuti many, deciduous. 



Ovipositor flattened, sometimes narrow. Ostium with 

 a plate; signa a pair, pilleate. 



The group pflugiana-circiana has been very carefully 

 investigated. Specimens vary greatly, and the variation 

 appeals to extend to the genitalia. We can find nothing 



thai enables us (u separate the so-called speries with an> 



greal confidence. We are also unable to say what Zeller's 

 original (irciinin reallx represents. Barretl is apparent l\ 

 correct in Btacing thai in pflugiana the female is smaller 

 than the male, whereas in circianu . as generally accepted, 

 the sexes are of the same size. There are further one or 

 two dwarf forms, notably one from the Pens, which ma\ 



prove to be distinct speeies.
