120. T. alecto, Linn. 



Sikhim and Bhutan, up to 8,000 feet. Occurs from May to October,, 

 and is extremely common at the lower elevations. The orifice in the- 

 palpus is round, and the setae are very distinct, almost filling the same. 



141. T. lutus, Cram. 



Sikhim and Bhutan, up to 4>0Q0 feet. Occurs from June to 

 October. The female is almost indistinguishable from one form of 

 T. lineosa, Wlk., except in the form of the palpus. The orifice in the 

 palpus is deeper than that of T. alecto, and the setae are not visible 

 externally ; the palpus itself is similar in shape. The larva, which 

 I have found on Cissea, the under surface of the leaves of which are 

 crimson, is itself crimson striated with brown ; there is a pink ocellus 

 on the fourth somite edged with yellowish-white above, and traces- 

 of oblique lateral lines ; the horn is purple-brown. 



124. T. lycetus, Cram. 



Sikhim, 1,800 feet. I have eight specimens of this species taken 

 in April, June, August and October. The orifice in the palpus is not 

 very apparent, being closely filled with long setse. 



125. T. oldenlandice, Fabr. 



Sikhim, 1,800 feet ; Bhutan, 2,500 to 3,000 feet. Occurs from 

 June to September and is commoner than the last ; the orifice is 

 slightly more apparent, and the setse fill up all except a minute pit 

 on the outside, which is conspicuous. 



126. T. silhetensis, Wlk. 

 Throughout India (Bampson). Neither Mr. Elwes nor I have 

 ever seen a specimen from Sikhim. 



137. T. velata, Wlk. 

 Sikhim and Bhutan. On examining the forms placed under this 

 species I find that three different species can be separated on the form 

 of the palpus alone, and I am also inclined to think that the forms 

 T. velata and T. aurifera, as figured by Butler, may be separable on 

 account of their markings, although the palpi are similar. It is 

 possible, however, that they may be seasonal forms. The following 

 key applies to all the specimens in my collection.
