Show 1891.] THE NAGA AND KAREN HILLS AND PERAK. 251 been so well described from a botanical point of view by Mr. C. B. Clarke, F.R.S., in the ' Journal of the Linnean Society, Botany,' vol. xxii. 1886, p. 128, that I need not say much about them here; but I extract from Mr. Doherty's letters some details of interest. He says, writing from Mao, Manipur, on September 9th, 1889 :- " I have not marked the altitudes exactly, as we ascend 2000 feet nearly everv day, and I know the exact elevation only of those I catch myself. Euplcea midamus ranges up to 6500 feet and is the only Euplcea found above 4000 feet. Limenitis austenia is confined to the low country. L. dudu is rather common, much more so than zuleima ; these species approximate to Parthenos (austenia is almost a Parthenos in structure) and are easy to catch. The numerous Celebesian species belong to that part of the genus nearest Athyma, Moduza, and Pandita, and are hard to catch : one characteristic of what I call the Nymphalidae (i. e. the Neptis-Euthalia-Limenitis group) is the entire absence of true genera; the structure is plastic, and one type melts insensibly into another. Besides Euthalia nara I send a female near it, but perhaps different (E. anyte $ )> and also what seems a new species, a local form of E. anyte, apparently quite distinct. Libythea rohini occurs only below 3000 feet. Nearlv all the Darjiling Erycinidae have turned up here, as well as several specimens of m y hitherto unique Everes kala, which is distinct from the Tenasserim species, E. umbriel, Doh. I also send Everes nyseus and parrhasius. Here the latter has the tails rudimentarv or absent. Among Ilerdce I send I. epicles, which occurs from the plains to 6000 feet, androcles from 6000-9000 feet, brahma 4500-5500 feet, tamu 4500-8500 feet. I. androcles is variable, the green hind wing almost disappears in some, and when flying they have the air of obscure black Butterflies. I send a large set of Dercas wallichii, which is curiously like Gonepteryx zaneeka of the North-west. It flew in June and disappeared in July. Leptocircus is very common in Assam, ranging up to 6000 feet [I found it in the Khasias only at low elevations in very hot dense forests.-H. J. E.]. I took it on the Dibong north of Sadiya, probably the northern limit of the genus. "Of Teinopalpus I send a broken male ; your account of its habits agrees exactly with what I have seen of it up here. I send a battered specimen of Papilio krishna, so all the four species of green Papilios (krishna,paris, ganeesa, and arcturus) are found here, but are provokingly rare. P. evan occurs at Margharita, but I have seen none here, though P. gyas is not uncommon. I send a fine female of P. rhetenor, also a single female of Aulocera loha, from an elevation of 5500 feet in Northern Manipur. "The Armandias sent seem to be slightly different from the Bhutan form. [The only difference I see is that they average smaller.-H. J. E.] It first turned up about August 10th, in the beautiful uninhabited Zulla valley, the border country between the Angami tribe and the Kachla Nagas, 10 to 15 miles from Kenoma, in the direction of Khonoma. It generally kept to the ridges, occasionally descending into the valley, once almost down to 5000 |
