117. Plesioneura paraltsos, n. sp. 

 Proc. As. Soc. Bengal, August 1881, p. 143. 

 <y . 5. Closely allied to P. alysos, but differing therefrom, on the upper- 

 side of the anterior wings, in the discal oblique semitransparent while 



lustrous band being broader with less irregular margins, and in only one 

 small spot, placed between the third median and thediscoidal veinlet, midway 

 between the discal band and the outer margin, being present ; 'and, on 

 the underside of the posterior pair, in having one or two small white opaque 

 lustrous spots, one near the end of the cell, the larger and the more 

 constantly present, and the other just beyond it between the first and 

 second median veinlets. 



Three males and one female. 



Length of anterior wing <? -78, o. -82 ; whence expanse = 1 1 66 

 o. 1-74 inches. 



Specimens from the Sikkim Hills ; Sibsagar (S. E. Peal), Dhunsiri 

 valley and Dafla Hills, Assam (fit H. Godwin- Austen) ; Trevandrum, 

 S. India (F. W. Bourdillon), and Ceylon (F. B. Mackwood) are devoid of 

 all traces of the spots on the lower surface of the posterior wings. 

 118. Plesioneura dan, var. andamanica, nov. 

 Pap. dan, Fabr., Mant. Ins, ii, p. 88 ; Hesperia fedih, Kollar in Hiigel's Kaschmir 

 vol. iv, pi. 18, figs. 5, 6.-*-Plesionmra dan, Moore, Proc. Zool. Soc. Lond. 1865 p. 789 



Our specimens from Port Blair differ from Continental ones in having 

 the discal series of spots all run together so as to form an unbroken band 

 and the three subapical spots conjugated and in the same straight line 

 with their conjoined inner margin nearly straight and their outer festooned • 

 and two examples exhibit in addition two smaller dots placed nearly par- 

 allel to the outer margin just below and external to the three subapical ones. 

 Numerous specimens.

Our large series of specimens from the Sikkim Hills, Cherrapunii in 

 the Khasi Hills, the N. W. Himalayas, Travancore, Ceylon, and S. Anda- 

 man furnishes us with an almost complete series of gradations between 

 those with the smallest number and the greatest amount of coalescence and 

 those presenting the largest number and the least coalescence of the spots 

 on the disk of the anterior wings ; moreover, the orange spots in the pos- 

 terior wings are to the last degree capricious in their development, beino*
