26 GROTE — SPECIALIZATIONS OF LEPIDOPTEROUS WING. [April 7, 



I. Vein iiig of primaries out of iii4 beyond the cell halfway to 

 apex : 

 2. Cell of hind wings disproportionately reduced : 



Hind wings greatly developed inferiorly, with long, pointed 



tail ( ist Group) Leptocircus. 



I. Vein iiig of primaries arises from radius more or less exactly 

 opposite to the point of junction of discal cross-vein : 

 2. Cell of hind wings subequal, narrowed outwardly by a down- 

 ward curve of cross-vein between iii and ivii 

 3. Vein iiii of primaries anastomoses with ii: 



Hind wings produced interiorly, with short, sharp tail.. . 



(2d Group) Idaides. 

 Hind wings produced inferiorly, terminating bluntly, 



without tail Zetides. 



Hind^wings not produced inferiorly, rounded, tailless. . . 



Arisbe. 

 Hind wings not produced inferiorly, with long, narrow, 



equal tail Pathysa. 



2. Cell of hind wings subequal, not narrowed outwardly (except 

 in Jphiclides) : 

 3. Vein iiii of primaries free to costa : 



4. Internal vein of hind wings shorter, running out on 

 internal margin before the longer excision at anal 

 angle : 



Hind wings tailless , (3d Group) Eurycits. 



Hind wings tailed Pachliopiera. 



4. Internal vein of hind wings longer, attaining the 



internal margin before the shorter excision at anal 



angle : (4th Group) 



\_PaptliOy Iphiclides, Jasoniades, Euphoeades, Heraclides, Laer- 



Has, Menelaides, Achil/ides, Orpheides, Nestor ides, Caiaides, 



Priamedes, Parides, Ithobalus, Iliades, Troilides, with the types 



given by Scudder, I am unable to separate by adequate neurational 



or wing characters in a table. They all generally agree, most of 



them exactly except by relative characters so obscure as to be of 



hardly more than specific value.] 



I. Vein iiig arises from radius above the cell and just before the 



junction of the cross- vein (5th Group) Trogonoptera. 



I. Vein iiig arises from radius above the cell and well before the 

 point of junction of discal cross-vein :
