4 TEEACOLUS. 



tbe apex of the primaries is almost black, and the indication of the second row of 

 spots is so faint that the latter are in most cases obsolete, and hence the species has 

 a much heavier black border to both primaries and secondaries. The black spot 

 above the sub-median nervure is much smaller as a rule, but not invariably, than that 

 shown by T. Calais. 



Teracohis camifer (Plate 1, figs. If) was described by Dr. Butler from a specimen 

 from Mynpuri in Mr. F. Moore's collection (P. Z. S. 1876, p. 138), and he after- 

 wards received the same form from Aden from Colonel Yerbury (P. Z. S. 1884, 

 p. 488) ; while he mentions that it has also been sent from Karachi by Colonel Swinhoe. 



In his latest paper (Ann. and Mag. Nat. Hist. (6) xx. p. 388) he considers his 

 T. camifer to be the " dry-season form " of his T. nmatus, with which he also unites 

 T. Calais. 



Mr. Guy Marshall also writes : " T. camifer is clearly a dry-season form of this 

 species, the bright green of the underside being modified into a sandy pinkish." 



I have only seen three specimens referable to T. camifer; they differ from 

 typical T. calais in their very pale coloration, the spots and markings on the 

 primaries being very pale brown, and the dusky brown bands on the secondaries 

 nearly obsolete, especially in the case of the inner line, which is only faintly 

 indicated. The rows of pale sub-terminal spots are thus rendered much more 

 conspicuous by the restriction of the blackish hind-margins of both wings, over 

 which is sufiused a general shade of reddish orange, especially distinct towards the 

 oasal portion on the secondaries ; there is a paler yellowish patch in the discal area 

 of the wing. 



Colonel Yerbury has very kindly given me the subjoined notes on the habits 

 of this species: "At Aden T. Calais is very abundant, and may be found anywhere, 

 Ijut it affects for choice bushes of Salvadora persica, on which plant Captain Nurse 

 found the eggs and larvje. 



" The eggs are laid in batches on the leaves, and the newly hatched larvae are 

 at first gregarious. Thej^ vary somewhat in colour, some being pea-green, darker on 

 the back, lighter on the flanks, and with a faint dorsal line ; others again are 

 darker, with a nearly white dorsal line. When lull-fed, they are about an inch long, 

 some having black heads and some green heads, but both forms may be reared from 

 the same batch of eggs. Tiie pu])se, too, vary somewhat, some being pale green 

 speckled with black. There is but little doubt that at Aden T. calais represents the 

 wet district form and T. di/namenc the dry, T. camifer being only a casual variety. 

 Heavy rain fell in May and June 1883, and early in July an unusually bright- 

 coloured form of this butterfly was on the wing among the Saloadora bushes in the 

 Gold Mohur Valley. This form was never again met with."
