those of Kollar’s zara in certain particulars ; but as Kollar never described the arrangement of 
the markings of his species, there is no basis whatever on which to found a comparison and 
to note the deviations, as Mr. Butler has attempted to do. 
This form, however it may be defined, falls under the general description of 7. ¢heophrastus, 
given above. It has no pretentions to be a geographical variety, as it occurs in localities 
so far apart and so diverse in physical aspects as Burma and N.-W. India; and it is 
stated by Mr. Butler to have a wide distribution in many parts of India,

T. altevatus, Moore, Proc. Zool. Soc. Lond., 1882, p. 245, pl. xii, figs. 4, 4@, male. 
Hasitat: Dharmsala, N.-W. Himalayas. 
EXPANSE: ‘83 of an inch. 
DESCRIPTION : “ Allied to 7. mara, Kollar, but smaller. UPPERSIDE, doth wings, colour 
paler, and of a more decided bluetint than in 7. mara. Forewing with a slender disco-cellular 
dusky lunule. Aindwing with a small dusky spot above the tail, and a slender marginal 
white line. UNDERSIDE, doth wings dull pale greyish-ochreous, with similarly disposed markings 
as in 7. xara, which are, however, more slender, paler, and much less distinct, those on 
the Aindwing being reddish-ochreous, the marginal metallic spots more or less golden. 
Cilia brownish-white. ” (Moore, 1. c.) 
The distinguishing feature of this species is the ochreous colour of the ground on the 
underside, and the attenuated markings of a reddish colour. From the description, some speci- 
mens of 7. extricatus, Butler, have the markings on the underside much the same colour 
(rust-red), but that species is said to have the markings below as in 7. theophrastus, Fabricius, 
while 7. alteratushas themas in 7. mara. But as explained above, no one can state in the 
slightest degree what was the arrangement of the markings of Kollar’s 7: mara. Of all forms of 
T. theophrastus this is the furthest removed from 7. zara, which, whatever other characters 
it may have had, was an insect with a white underside and black markings : this form has a pale 
ochreous-grey underside with very slender and pale reddish-ochreous markings. It is in fact 
the best-marked form of 7. theophrastus which has yet received a name, and is the most likely 
of them to be established as a separate species, should this be the case with any of these forms. 
Colonel Lang reports that isa common form inthe Punjab in the winter, affecting arid 
ground and especially avenues or plantations of Acacia arabica, on which he used to think 
the larva fed: he never however found the larva. It may be the dry-season form in those 
localities of some darker-coloured wet-season form of 7. theophrastus. I possess typical 
specimens from Kattiwar, Kulu, and from Bholahat in the Malda district.

DESCRIPTION : ‘* Paler than 7. zava, Kollar, on the UPPERSIDE ; varying in size even 
more than 7. dalkanica, Freyer, UNDERSIDE readily distinguished by the much greater 
regularity of the markings, those of the forewing being arranged nearly as in 7. theophrastus, 
Fabricius (z, ¢., the medial stripe [on the forewing] is often unbroken, the subcostal spot beyond 
sometimes confluent with it so as to forma [-shaped marking ; the dashes beyond the medial 
stripe placed transversely and always confluent instead of forming an interrupted <-shaped 
character) ; the markings of the Aindwing vary in colour from rust-red to black, but corres- 
pond in character with those of 7. mara.” (Butler, 1. c.) ; 
‘* Taken in Karachi in May, October, and December, 1885, and in January and April, 
1886.” (Swinhoe). 
7. extricatus, asabove defined, appears to be an insect varying from *6” to 1'2” in expanse : 
of a pale violet tint, having the medial striga of the forewing below offew unbroken (as this
