Pirates XXXI, XXXII. 
In the autumn of 1910 I found that Mr. Felix B. Pratt, 
who had been collecting for me with his brother in Dutch 
New Guinea, was willing to take another trip. 
After consultation with Sir Geo. Hampson as to the 
most likely country for undescribed insects, I decided to 
ask Mr. Pratt to make a brief expedition to Madagascar 
on my account. 
He arrived early in January 1911 at Tamatave, and 
acting on my instructions, made search for a locality in the 
forest at an elevation of about 3,000 ft. This I have found 
to be the best altitude for general collecting in the tropics, 
and he was working in about latitude 18° South. 
He was directed to a station, Nunamang, some distance 
along the line from Tamatave to Anantanarivo, but found 
when he arrived that it did not at all fulfil the conditions 
he wanted, and he therefore fell back upon Perinet, and 
from thence worked to a place rejoicing in the name of 
Nalamagaotna, which is some 2,500 ft. above the sea and 
has plenty of deep wooded valleys. 
Almost all the insects taken were found here, both 
butterflies and moths, and the latter were for the most 
part taken at light, with the aid of a magnesium lamp 
placed in a verandah surrounded with white sheets. 
Unfortunately, fever contracted in New Guinea attacked 
him here, and he was obliged to seek medical advice at 
Anantanarivo and rest there for some time; but before 
returning home he went again to his old locality, and 
succeeded in nearly doubling the number of insects taken, 
finally returning with about 3,000 moths and 600 butter- 
flies. Considering that he was in the country barely 
three months, and that part of the time was spent in finding 
a good locality, he evidently did well. On the other 
hand, any one going at a different time of year would 
certainly take other species, and possibly both the higher
