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 every day, and I know the exact elevation only of those I 

 catch myself. Euploea midamus ranges up to 6500 feet and is the 

 only Euplcea found above 4000 feet. Lime?iitis austenia is confined 

 to the low country. L. dudu is rather common, much more so than 

 suleima ; these species approximate to PariJienos (austenia is almost 

 a Parthenos in structure) and are easy to catch. The numerous 

 Celebesian species belong to that part of the genus nearest Atliyma, 

 Moduza, and Pandlta, and are hard to catch : one characteristic of 

 what I call the Nymphalidse {i. e. the Neptis-Eutlialia-Limenitis 

 group) is the entire absence of true genera ; the structure is plastic, 

 and one type melts insensibly into another. Besides Eutlialia nara 

 I send a female near it, but perhaps different {E. anyte 5 ), and 

 also what seems a new species, a local form of E. anyte, apparently 

 quite distinct. Libythea rohini occurs only below 3000 feet. 

 Nearly all the Darjiling Erycinidas have turned up here, as well as 

 several specimens of my hitherto unique Everes kala, which is 

 distinct from the Tenasserim species, E. umbriel, Doh. I also 

 send Everes nyseus and pai'rlmsius. Here the latter has the tails 

 rudimentary or absent. Among Ilerdce I send I. epicles, which 

 occurs from the plains to 6000 feet, androcles from 6000-9000 

 feet, fira/wza 4500-5500 feet, ^awm 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 wallicliii, 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, ffaneesa, and arctwus) 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 fiue 

 female of P. rlietenor, also a single female of Aulocera lolia, 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 lOtli, in the 

 beautiful uninhabited ZuUa valley, the border country between the 

 Angami tribe and the Kachla Nagas, 10 to 15 miles from Keuoma, 

 in the direction of Khonoma. It generally kept to the ridges, 

 occasionally descending into the valley, once almost down to 5000
