BURALINM 253 



characters except in the genera Callophrys and Strymon, in which there is an elongated 

 narrow shining patch of differently formed scales from those of the rest of the wing, at 

 the end of the cell of the forewing above, extending slightly into the cell, and beyond 

 its end, a small anal lobe, somewhat produced in Callophrys. The genitalia of Ruralis, 

 Strymon and Callophrys, Bethune-Baker informs us, are similar ; clasps, tegumen and 

 sedseagus entirely after the same pattern. Much diversity in the coloration of the 

 wings on the upperside, purple, purplish-brown, dull green, brilliant metallic green, 

 blue and some brown, with oehreous markings, all are purely palsearctic. The genus 

 Listera is altogether aberrant, it has three sub-costal nervules and a sexual tuft of 

 hairs on the forewing ; its venation is akin to those of this group, but its shape is 

 entirely diflFerent ; the only known species is represented by an example in the Indian 

 Museum, Calcutta, which we have not been able to examine ; we put it into this group 

 because de Niceville, the author of the genus, has done so.

Eyes hairy. Forewing, vein 12 ends on costa opposite end of cell, 11 emitted a 

 little beyond the middle of the cell, 10 at one-third before the end in the male, at 

 about one-fifth in the female, 7 ends at the apex of the wing, 5 from above the middle 

 of the discocellulars in the male, exactly from the middle in the female ; discocellulars 

 straight, equal in length, vein 3 emitted some little distance before the lower end 

 of the cell, sub-median nervure straight ; male with a long, narrow, shining patch of 

 diflferently formed scales on the upperside, at the upper end of the cell, extending slightly 

 into the cell and beyond its end. Hindwing with all the margins even, the wing 

 produced and somewhat angled at the end of vein 6, a somewhat long, narrow tail at 

 the end of vein 2, a small anal lobe ; vein 8 much arched at its base, 7 emitted at some 

 distance before the upper end of the cell, internal nervure very sinuous. Antennse long, 

 club elongate, gradually formed, palpi short, obliquely porrect, second joint bristly 

 beneath, third naked, legs short, scaly. 



Larva, as described by Westwood (Gen. Diurn. Lep. ii. p. 482), short, onisciform, 

 thick or linear-oblong, and depressed and attenuated at each end, generally clothed 

 with very fine, short hairs. 



Pupa, short and smooth, head rounded, attached by the pointed tail, and girt across 

 the middle.
