that it is quite evident what trouble is involved in moving from ])lace to place. 

 However, the troubles were overcome, and the first consignment arrived in excellent 

 condition. The drought broke in December 1902, and then Mr. Pratt retraced his 

 steps, stopping a while at Ekeikei, which proved to be a very rich collecting ground 

 and a useful depot. Here, however, as with Mr. Meek (auteii p. 310), an epidemic 

 of German measles broke out; fortunately it was scarcely so serious as that fmm 

 which Mr. Meek suffered later on, for Mr. Pratt managed to keep his camp going, 

 and as soon as possible made for the interior. By this time his son had picked up 

 the language, and carriers were obtained who took the party up to the Kebea range. 

 This mountain, with its various spurs, is some (jOOd feet high, and is situated a 

 day's march due east of Dinawa. The main camp was built here for this second 

 e.xpeditiun, and a much larger and more valuable collection was made and received 

 in excellent condition. 



The material now in my hands (i.e. not only that collected by Mr. Pratt, but 

 also that sent by Mr. Meek from the Aroa River) is so considerable that I can only 

 deal with the higher groups down to the Noctuidae, leaving that large group for a 

 later paper. We feel, however, that we can highly compliment Mr. Pratt, not only 

 on the richness of the collections, but also for his great tact iu dealing with the 

 natives ; this, no doubt, was partly due to his son being able to so soon pick up the 

 language, which fact gave him considerable influence over the villagers, with many 

 of whom he established most friendly intercoarse, so that he was thus able to carry 

 ou negotiations and deal with turbulent natives in a manner that would have been 

 quite impossible if he could not have conversed with them in their own tongue. 



I have followed in the main the arrangement of families obtaining in the 

 National Collection ; and I must here express my best thanks both to Sir George 

 Hampson and to Mr. Heron for constant help in working out the collections. My 

 method of measurement has been to take the line from the centre of the thorax to 

 the apex of the primary and to double it. 



LYCAENIDAE. 

 Parelodina gen. nov. 



cJ. Eyes hairy, palpi ascending, with second segment long, thickly clothed with 

 hair which forms a fringe beneath, end segment moderately long, dejjressed. Nenra- 

 tiou similar to CamlaUde.'i Huhu., except that in the primary veins 7 and 8 on a long 

 stalk rise from the cell well before the npper angle, whilst 11 is curved sharply 

 upwards and touches 12, which latter does not approximate to 11. In Hiibner's 

 genus vein 12 is distinctly depressed towards 11 at its (the latter's) origin, whilst 

 1 1 is not bent up towards it, but goes straight to the costa, the two veins being 

 quite apart all the way. 



Type : P. aroa spec. nov. 



1. Parelodina aroa spec. nov. 



S. Both wings white above, with a very restricted blackish basal area, over 

 which is a considerable irroration of blue scales. The primary has a very broad 

 black apex from the middle of the costa and extending broadly down the termen 

 to vein 2, where it abruptly ends ; the costa is black, incruising basewards as well 

 as towards the apex. Beneath, the wings are spotless white, though the black
