No explanation of any kind is given as to how this differs from Salpinx of Hiibner, or from 

 Salpinx as restricted by Butler, or why the older name has been dropped. E. superba and its 

 allies certainly differ from other species of Salpinx in the form of the sexual brand of the fore- 

 wing, but it is more probable that they are really different forms of a single species than a 

 group of species forming a distinct genus. 



Se7 to the Indian species of SALFZITX. 



A. Forewing comparatively narrow and elongated, the apex acute. Males with a prominent elongate 

 sericeous streak on the forewing, somewhat as in true Euplaa, scarcely visible on the underside. 

 All more or less shot with brilliant blue ; and with a prominent lilac spot in the eel! o< the forewing 

 on the underside. 

 a, Forewing with numerous violet or while spots in three series. 



a.* The brilliant blue shot reaching the submarginal row of spots on the forewing ; the border 

 spots of the hindwing white and prominent. 



37. E. [Salpinx) superba (North India?), China. 



^.' The brilliant blue shot reaching the marginal row of spots on the forewing. 

 a.* The border spots on the hindwing very indistinct or obsolete. 



38. E. (Salpinx) rogenhoferi, N.-E, India, Burma. 

 b.- The border spots on the hindwing pale, but distinct. 



39. E. (Salpinx) irawada, Burma. 



i. Forewing with few and indistinct spots, no series complete ; the border spots of the hindwing 

 white and prominent. 

 «.' The brilliant blue shot variable in extent, but usually covering the basal two-thirds only of 

 the forewing. 



40. E. (Salpinx) Margarita, Tenasserim. 



B. Forewing shorter and very broad. Males with a broad short oval sericeous brand, not prominent, gene- 



rally concolorous with, but paler than, the ground-colour, visible on the underside as a raised dark 

 spot. The blue shot less brilliant and often wanting ; no spot as a rule in the cell of the forewing on 

 the underside. 



a. Forewing very broad, with a decreasing tovi oi s\ihmSirgiQ3.\ spots, the third largest ; border spots 

 of the hindwing small but prominent, 

 a.^ Forewing brown, sometimes faintly glossed with blue at the base. 



41. E. (Salpinx) crassa, Burma. 



42. E. (Salpinx) erichsonii, Burma. 

 i.'^ The basal area of the forewing brilliant blue. 



43. E. (Salpinx) masoni, Burma. 



i. Forewing less broad, with the row of submarginal spots all nearly equal-sized. 



a.^ The blue shot usually suffusing the entire forewing, but very vaiiable in intensity. 



44. E. (Salpinx) klugii, N.-E. India. 



45. E, (Salpinx) grantii, Cachar. 



^.' The blue shot brilliant, but not reaching the outer margin of the forewing ; the discal series 

 of spots abbreviated, the third considerably the largest. 



46. E. (Salpinx) illustris, N.-E. India. 

 E. (Salpinx) chloh, Malayana. 



E. (Salpinx) .egyptus, Malayana. 

 c.» The blue shot usually entirely wanting, faintly present in some specimens ; the forewing 

 brown, with border spots as in E. core. 



47. E. (Salpinx) sinhala, Sikkim, Calcutta, S. India, Ceylon. 



C. Forewing shaped much as in the preceding group. Male with a broad violet streak ou the interno- 



median area ; visible on the underside as a dark raised spot. 



a. Forewing with no large white patch from middle of costa ; the hindwing without white basal 



streaks on the upperside. 

 a.' Forewing shot throughout with deep blue ; with prominent violet spots. 



a.- The marginal series of spots partially present near the hinder angle of both wings. 



48. E. (Salpinx) vestigiata, Malayana. 

 b.^ The marginal series of spots absent from both wings. 



49. E. (Salpinx) novar>e, Nicobars. 



*.» Forewing blackish-swarthy ; the hindwing with the anal angle white. 



50. E. (Salpinx) leucogonvs, (N.-E. India?), Malacca. 



b. Forewing with a large white patch from middle of the costa ; the hindwing with white basa

 <t.* Wings shot with deep violet-blue. 



51. E. (Salpinx) rhadamanthus, N.-E. India, Burma.
