very difficult, of access and lias not been visited Ly entomolo- 

 gists except when Dr. Perkins and Mr. Koebele made a trip 

 into them about 15 years ago. They reached the main ridge 

 from Wailna, following a large valley and taking three days to 

 reach the higher part of the mountains, where they remained in 

 camp for a few weeks collecting in the surrounding regions. It 

 was found to be a rich collecting field. This part of the Ilange 

 has now been made easily accessible by a trail which has been 

 cut up the Punaluu Ridge on the windward side of the moun- 

 tains. This trail was cut in an investigation of the water re- 

 sources of the region, and there is a galvanized iron roofed 

 camp used hy the men engaged in that work, and which now 

 furnishes a convenient shelter for tramping parties, this having 

 become a favorite place for those desiring to camp a few days 

 in the mountains. 



On June 11th, 1911, I spent the day up this trail, not reach- 

 ing the top, but getting into some good collecting ground where 

 I spent the short time available before beginning the descent, as 

 I had to return the same day. The best arrangement would be 

 to plan on staying over night, or several nights at the camp, for 

 the best results. In my short time for collecting, I was able to 

 secure a great deal more than I have been accustomed to in a 

 day in the mountains in the vicinity of Honolulu. As an indi- 

 cation of the possibilities of this region, I give the following 

 list of my captures though 1 am not able at present to give the 

 determinations of all the species. Several of the moths listed 

 are "not from specimens collected, but from caterpillars ob- 

 served. Several species of dragonflies were also observed, but 

 not captured.
