1895.] L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. 445 



Sumatra which lies between Nias and Penang. I may remark also 

 that I wrote blindly in Butt, of India, vol. iii, p. 21, when I sug- 

 gested that tbe genus Miletus belongs to the Gerydus group ; at the 

 time of writing I had seen no specimen of true Miletus. Previous 

 writers had used Miletus and Gerydus for symethus, Cramer, which led me 

 astray. " Miletus " zymna would appear to be a true Gerydus, but as 

 it was described from Ashanti, is not likely to be found also in 

 Sumatra. The nearest Sumatran species to which it is superficially 

 allied is G. gmtulus, de Niceville. 



291. Paragerydus horsfieldi, Moore. 



Grose Smith as horsfeldi [sic]. Hagen. Very common everywhere 

 over the whole of our area. Very variable in size, some females being 

 much smaller than the average of males. Also variable in the colora- 

 tion of the underside, some Sumatran specimens approach very closely 

 to P. taras, Doherty, from Burma, but none of them have " the apex 

 [of the forewing so] widely tinged with rufous-brown " as in that 

 species. 



292. Paragerydus panormis, Elwes. 



Allotinus panormis, Elwes, Proc. Zool. Soc. Lond., 1892, p. 619, pi. xliii, figs. 8, 

 male ; 9, female. 



Rare, but occurs at Bekantschan in February, August, September 

 and November, so probably generation follows generation afc short 

 intervals. May be recognised at once by the apes of both wings 

 on the underside being greatly infuscated. I have placed it in the 

 genus Paragerydus rather than Allotinus, as it has the upper discoidul 

 nervule of the forewing originating well beyond instead of at the apex 

 of the discoidal cell. 



293. Paragerydus p^tus, de Niceville. 



P. psetus, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. ix, p. 269, n. 7, pi. O, 

 fig. 12, male (1895). 



A very distinct species from Bekantschan and at higher eleva- 

 tions. Flies in February, March, and again in November. 



294. Paragerydus portunus, de Niceville. 



P. portunus, de Niceville, Journ. A. S. B., vol. Ixiii, pt. 2, p. 27, pi. v, fig. 14. 

 male (1894). 



' The very dark colour of the underside will suffice to distinguish 

 this species ; Sumatran specimens are even darker than typical ones 

 from Java, the ground-colour being pale ferruginous instead of pale 

 oclireous, with dark ferruginous mottlings. Is commoner than the
