being greenisli-yellow set witli dark scales. Tlie markings are almost 

 exactly alike. The prehensores are singularly different : Seen from 

 above, tlie uncus of dara is gradually acuminate, that of moeso'ides 

 abruptly truncate and slightly bilobed ; seen from the side the uncus 

 of dara is slender, tapering and pointed at the tip, that of vioeso'ideSj 

 which is surmounted by a prominent tuft of hairs, is blunt and rounded 

 at the tip ; the clasp of dai'a is much more slender than in moeso'ides^ 

 and its terminal hook much more produced and bent. 



The prehensores of the HesperiadcB are by no means so constant 

 as those of other butterflies, and are lacking in generic characteristics. 

 Nevertheless, their study seems to me absolutely necessary to any clear- 

 understanding of the species. 



yi. — On a second Species of JJredine affecting Abies smithiana, Forbes,

(With Plates lY. & V.) 



The Himalayan spruce-fir {Ahies smithiana, Forbes) harbours yet 

 another uredine. This tree, as I have already mentioned in a former 

 paper,* is not common in Simla, though very common at slightly higher 

 elevations a few miles beyond the station. A few, however, do occur in the 

 station, and on three of them this second species of uredine was found. 

 Two of these grow in the garden of a house towards the western side of tho 

 station, and were most probably planted there for ornamental purposes^ 

 whilst the third grows in an open, though preserved, forest on " Jakko," 

 a peak towards its eastern end about two miles as the crow flies from 

 the first mentioned locality. I noticed the parasite for the first time 

 early in July when it was in all cases fully mature. 



The abnormal appeamnces caused by the growth of this fungus 

 differ very widely from those already described as characteristic of in- 

 fection by the first described species. The whole tree is generally be- 

 sprinkled with the fungus, and it is then conspicuous by the amount 

 of yellow discoloration occasioned. In this affection also the young- 

 est shoots only are attacked, not one of the needles of the preced- 

 ing year's growth being involved. A marked difference, however, in
