 35. Amathusia portheus. 



A. portheus, Felder, Eeise Novara, Lep., vol. iii, p. 461, n. 780 (1867). 



Two males from the forests around Silcuri, 3rd and 5th August, and 



one female from Rupacherra in the Hylacandy subdivision, where it 



was obtained by Mr. Chalmers, by whom it was generously presented to 



Mr. Wood-Mason. One male forewing was also picked up near Silcuri. 



36. DiSCOPHORA TULLIA. 

 Papilio tullia, Cramer, Pap. Ex., vol. i, pi. Ixxxi, figs. A, B, female (1775). 

 Thirty-one males and four females in the forests around Silcuri 

 between 11th May and 25th August. 



37. Enispe euthtmius, PL XV, Fig. 1, S . 



AdoUas euthymius, Doubleday, Ann. and Mag. of Nat. Hist., vol. xvi, p. 179 

 (1845) ; Enispe tessellata, Moore, Proc. Zool. Soc. Lond., 1883, p. 521. 



One male, 8th September, on ISTemotha, agrees exactly with the 

 description of E. tessellata from Nepal and Sikkim. The type speci- 

 men of E. euthymius was from the Himalaya Mountains, to which locali- 

 ty Sylhet and Assam were added in the ' Genera.* B. euthymius is, judg- 

 ing from the specimens in the Indian Museum, Calcutta, an eminently 

 variable species, whose variations are in no way related either to locality 

 or to geographical range, so that even the term * local race ' cannot 

 be applied to the extreme dark form named E. tessellata by Mr. Moore, 

 and here figured. 



38. Thaumantis diores. 



T. dior&s, Doubleday, Ann. and Mag. of Nat. Hist., vol. xvi, p. 234 (1845). 

 Two males, 6th September, and one female, 2nd October, on Nemo- 

 tha. 



Mr. Wood-Mason notes that " the scent -fans of the male are vanilla- 

 scented." 



39. Stichophthalma camadeva. 



Thaumantis camadeva, Westwood, Cab. Or. Ent., p. 9, pi. iv (1848). 



Very common in the month of May in the forests near Silcuri 

 (Irangmara), forty males and three females having been taken between 

 the 7th and 20th, on which latter date, as enough females had already 

 been obtained for examination in the fresh state and for the zoological col- 

 lection, the collector Motiram was told to catch no more specimens. Two 

 more males were, however, subsequently brought in on 6th and 21st July. 

 "The gland," Mr. Wood- Mason notes, "covered by a patch of 

 modified scales and by an erectile whisp of hairs on each hindwiug in the
