torum marginibus posticis albis, alis cinereo-albis venis nigro margi- 

 natis, anticis nigro quadrimaculatis, posticis nigro unimaculatis. 

 Male. Cupreous black, slender, white beneath. Head and thorax with 

 white dots. Abdomen with a white line along each side, and with a 

 white band on the hind border of each segment. Wings cinereous 

 white, with black stripes along all the veins ; exterior border black. 

 Fore wings with four irregular black spots, two of them subcostal, 

 and two near the interior angle ; costa very convex. Hind wings with 

 a subcostal black spot. Length of the body 9 lines ; of the wings 30 

 lines. 



This species in its wing-markings has a great likeness to the genus 

 Histia. 



52. Cyclosia pieroides, n. s. Mas. Nigra, subtus alba, capite 

 thoraceque albo notatis, thorace postico abdomineque glaucescenti- 

 caeruleis, alis albis caeruleo venosis, anticis apud marginem exteriorem

Male. Black, white beneath. Head and thorax with white marks. 

 Antenna; moderately pectinated. Thorax hindward and abdomen pale 

 glaucous blue. Wings white ; veins blue. Fore wings above with 

 the veins broadly bordered with black towards the tips, where the

 with black. Hind wings tinged with yellow beneath, where the veins 

 are more black-bordered than on the upper surface. Length of the 

 body 8 lines ; of the wings 22 lines. 



The resemblance of this species, of C. dissimulata, and of C. ficta, to 

 some species of Pieris is very remarkable.
