Longicornia Mai ay ana.

1855j and the next day commenced work. I rarely went 

 more than a mile from the house^ and I may safely say 

 that nine-tenths of my insects were collected on a piece 

 of ground about half a mile square. The following state- 

 ment of the progress of my collections will show what a 

 wonderfully rich spot this was. 



During almost the whole month of July, I was con- 

 fined to the house by a wound in my foot, and only 

 obtained a few specimens from the Chinamen, and from 

 my assistant, Mr. Allen, who was then very young and 

 inexperienced. Almost the whole of the thirty-four 

 species of Longicorns obtained before arriving at 

 Simunjon, were found there also, so that I collected 

 about 270 Longicorns in six months on a square mile of 

 ground. A considerable number of these were single 

 specimens, and even when several specimens were ob- 

 tained, they were, in many cases, found only on one 

 spot and on one occasion. This gives a kind of acci- 

 dental character to a large part of the collection, and 

 renders it probable that this limited tract was not even 

 approximately exhausted. Until, therefore, other locali- 

 ties in Borneo are thoroughly worked under equally 

 favourable circumstances, it is impossible to form any 

 estimate of the total number of species of Longicorns 

 which may exist in that vast island. 



Macassar. Although I spent nearly seven months in 

 Southern Celebes, I obtained few beetles, and especially 

 few Longicorns. This is owing to the country being so 

 very open and so much cultivated, and to the seasons 

 being so extreme; for seven months excessive drought, 

 and for five a deluge of water. The forests of the interior 

 would, however, no doubt produce many fine new 

 things.
