//^/7>.— Solomon Islands, July-August, 1909(W. W. Frog- 

 gatt. No. C 4). This and the following species are named 

 after explorers connected with the Solomon Islands. This is 

 a very fine species, of Austro-Malay, not Australian, type. 

 Superficially, it looks much like ChaVtcndoma sicula Rossi. It 

 appears to be related to the Hawaiian M. schauinslandi 

 Alfken, but the latter is smaller, with the ventral scopa 

 mainly pale, the first dorsal segment densely red-haired right 

 across, and otherwise different.
