226 THE CANADIAN ENTOMOLOGIST. 



roides and Perreyia. He says: "This group has usually been regarded 

 as a section of the Lophyrina ; but it differs in so many points not only 

 from that group, but from all others, that I am justified-, I think, in 

 making a distinct section of it, and have given above the distinctive 

 characters of the subfamily."* 



Below I have placed in the group several other genera placed else- 

 where by Cameron and Kirby. No species is known in our fauna, and 

 the group, as a whole, seems to be confined to the Neotropical and 

 Australian regions. 



The genera belonging to the family may be readily distinguished by 

 the aid of the following table : 



Table of Genera. 



Marginal cell simple, not appendiculate 7. 



Marginal cell appendiculate, the lanceolate cell petiolate. 



Second and third siibmarginal cells each receiving a recurrent 

 nervure, rarely with the first recurrent interstitial with the first 



transverse cubitus 3. 



Second submarginal cell receiving both recurrent nervures ; antennae 

 13-15-jointed 2. 



2. Hind wings without a discal cell, the marginal cell with an appendage ; 



$ antenn;e 15-jointed, biramose Lophyroides, Cameron. 



(Type L. ruficollis. Cam.) 

 Hind wings with one discal cell, the marginal cell without an append- 

 age ; $ antennae 14-jointed, ^ 15-jointed; maxillary palpi 4-, 



labial palpi 3-jointed Lophyridea, Ashm., n. g. 



(Type L. tropicus, Nort **) 



Hind wings with one discal cell, the marginal cell with an appendage ; 



antennae 15-jointed in both sexes; maxillary palpi 2-, labial palpi 



I -jointed Perreyia, Brulle'. 



3. Hind wings with one discal cell (a closed submarginal) 4. 



Hind wings withotit a discal cell. 



$ antennae 1 3-jointed, the third joint very long, the following 

 gradually shortening Ancyloneura, Cameron. 



4. Antennae i6-jointed, longer 'than the body 6. 



Antennae 9-1 i-jointed, shorcer than the body 5.

 Cameron placed this species in his genus l.op)iyroidcs.
