 quarum postica distanti. — The violet mouth and columella,

 below the angle, are all peculiar. 



5. Julietta (f. 5, 6), Duclos, Oliva, pi. 16, f. 3, 4. — Ovato-

 pallida, flammulis strigata, balteo angulatim flammulato; 

 columella laevigata, callo antico parvo, plicis paucis fere ob-

 fusiformis, pallidissime carnea fusco undulatim flammulata,
