HETEROCEEOTJS LEPIDOPTERA. 183 



Pam. OMMATOPHOHID^. 



This family is especially Asiatic ; and the two new genera here 

 characterized recede much from the typical structure. The very 

 long 3rd joint of the palpi is the chief distinctive character of 

 Allia. Erymella hardly belongs to the Ommatophoridae. 



Earn. OPHIUSID^. 



The woolly covering of the pectus, of the base of the abdomen 

 beneath, and of the legs distinguishes Varia. It may be considered 

 an aberrant form of the Ophiusidfe. 



Fam. POAPHILID^. 



Fhurys teligera differs very much from all the other species of 

 the genus ; it is most like P. hasilaris, but there is no longitudinal 

 streak near the base of the fore wing. 



The curved palpi and the structure of the fore wings distinguish 

 Batia from Poaphila and from Phurys. 



Pam. THERMESID^. 



Thermesia Upmtulata is nearly allied to T. prospera ; but the 

 wings are without the postmedial white line which characterizes 

 the latter species. 



Mandela has most affinity to Ephyrodes ; but the wings are fes- 

 tooned, and the exterior border of the hind wings is not angular. 



Pam. HYPENID^. 



Sypena megaspila is most allied to H. pilosalis ; but the latter 

 has no concise silvery line along the patch of the fore wings. 



The more porrect tips of the fore wings distinguish Lametia re- 

 tusa from i. ignitalis. Plusiodonta anaitoides (Cat. Lep. Het. 

 xxxiii. 843) may be transferred to this genus. 



Fam. HEEMINID^. 



In this family Casperia belongs to a distinct group, of which 

 Mesopia is the only other representative. Mastygophora and 

 PaUTiis are the types of two neighbouring groups. 



Fam. UEAPTERYD^. 



The genus Chcerodes extends from Nova Scotia to Eio Janeiro. 

 Clysia is a South- American genus ; and O. discolor has "a, general
