﻿MOTHS OF GENUS EPEIROMULONA — FIELD 457 



whereas in Mulona vein 2 is downward curved at base. Vein 5 of hind- 

 wing is present in Gaudeator and Epeiromulona^ absent in Mulona. 

 Veins 3 and 4 of liindwing are usually connate or separate in Gaudea- 

 tor^ stalked in Mulona and Epei7'oviulona. Epeironiulona is easily 

 distinguished by the male and female genitalia from the other two 

 genera. In males of Mulona the juxta is bifurcate and U- or V-shaped. 

 In Epeiromulona the juxta is H-shaped and in Gudeator a broad, 

 slightly curved plate. The transtilla is absent in Epeiromulona and 

 present in Mulona and Gaudeator. The aedeagus is short and broad in 

 Mulona., short and not so broad in Gaudeator., and is rather long in 

 EpeiroTnulona. Numerous cornuti are present on the vesica in Gaude- 

 ator and Epeiromulona and absent in Mulona. In females of Mulona 

 the middle two-thirds or more of bursa copulatrix is heavily serra- 

 tulate while Gaudeator and Epeiromulona females are not serratulate 

 but contain instead two areas of armature, one each at anterior and 

 posterior end of bursa copulatrix. The anterior armature in Epeiro- 

 mulona consists of a ribbonlike scobinate plate and in Gaudeator this 

 armature consists of a small, nearly round scobinate plate. The 

 posterior armature in Epeiromulona consists of a bifurcate plate 

 covered with short spines and in Gaudeator this armature consists of 

 a collar covered with long spines, this collar almost half encircling 

 bursa copulatrix near entrance of ductus bursae.
