44 GROTE — SPECIALIZATIONS OF LEPIDOPTEROUS WING. [Jan. 21, 



Explanation of Plate III. 



The figures are obtained by combined photographic process. The veins are 



numbered according to the system Redtenbacher-Comstock. 

 iii =z radius, iv = media, v = cubitus. 



Fig, 14. Oeneis noma. Type of genus. Attention is directed to the fact that 

 this is a more generahzed form, belonging to the Agapetinae with iv^ 

 from cross- vein, by the strongly closed cell and equidistance of the 

 branches. The position assigned by Mr, Scudder, " at the head " of 

 the brush-footed butterflies, cannot be a proper one. The genus 

 seems related to Erebia (/, c, Fig. 23). 



Fig, 15. Heliconius antiochus. Type of genus and family. From its total 

 characters a more generalized type than that of the Agapetidae. 



Fig. 16, Lininas chrysippus. Type of genus and family. Still more gener- 

 alized. Attention is drawn to the strong condition of vein viii on 

 fore wings. 



Fig. 17. Libythea celtis. Type of genus and family. Outline of wings resem- 

 bling Polygonia. Vein viii of primaries strong and position of ivj 

 nearly central. In other characters specialized, ii and iii on hind 

 wings fused to issue of i. 



Fig. 18. Etischatzia morvus. Type of genus. The radial branches have in- 

 tersected with subcosta. A long fork ; furcation of iii^ and iii^ long» 

 but shorter than in Charaxes, Compare text.
