 Tlic writer is tiMiiptcMl to prolonj^ this dii^rcssioii, and to 

 liiijicr ill iiu'iiiory over tlu; beauty of the spot where these 

 captures were made. One recalls the forest-clad ravine, not 

 penetrated by the direct sunlight up to the time of our 

 departure at lO.'iO A.M. ; the cliff, with the water coursinf; 

 <lown it, and great tussocks of hanging grass growing in its 

 crevii'cs; a huinniing-l)ird visiting the scarlet clusters of 

 Howcrs on a tree {liruii'iicn) l)y the side of tin; lall ; a great 

 l)lne Morjiho settling on the rock close to the water, and two 

 Jle/icunius, with vivid orange-red patches on the fore wings, 

 circling over the frothing pool at the foot of the cascade.

Diar/nosis. — Length 1-0 nun. Antenuie short, two- 

 jointed. Dorsal surface furnished with stout spines. 

 JJranehial filaments arranged in tufts, 10 filaments in 

 cacli tuft in the full-grown larva, iiateral processes well 

 developed, simple, |)edilorm, ciliatc, without long setie pro- 

 jectintj^ bt'vond the eiliie. Sixth segment with only one 

 pair of lateral processes, and with its hind niurgin bearing 

 bi.x long setie arising from four places. 



The following is a more detailed description of the larva, 

 in the making of which I have been guided largely by Fritij 

 Midler's well-known and fine; work (cited in list). 



Lent/f/i, varying among thirty-nine larvie, f rom J'5-G mm. 

 One larva, only paitly grown, measures only 'S'2~) mm. 



Co/our above dark brownish : the posterior margin of the 

 cepiialothoraeic and of the four intermediate segments pale, 

 widtish ; the rounded posterior margin of the terminal (si.vth) 

 j^egment darker, i)lackish ; the anterior part of the cephalo- 

 tlior;ix, comprising the five "cephalic areas '^ of F. .NUiller, 

 is also somewhat infuseate, darker than the posterior j)art ; 

 antcnuie blackish ; lateral processes yellowish brown, eili;e 

 pale. \'cntr.illy the colour is very much lighter, the mediau 

 part of each segment, surrounding the sucker, being 

 whitish. 



i</jines. Scales. &fc. — The disposition of the larger spines on 

 the dorsal surface is described in detail I)eh)W, i?ut, bi-sides 

 these, a very high po«er sho«s that the whole dorsal surface 

 bears, scattered at rather wide intervals, very minute, colour- 

 less, erect, shortly lanceolate scales, of the same nature as 

 tiiose figurid by F. Miiller on pi. 4, figs. 15, 10 of his work,
