IX.— Gollembola from Mt. Murud and Mt. 

 Dulit, in Northern Sarawak. By Dr. H. 



SCHOTT. 



(With ttco Plates.) 



Some time ago the late Curator of the Sarawak Museum, 

 Dr. E. Mjoberg, requested me to work up a collection 

 of Gollembola, made during his expedition in the regions of 

 the upper sources of the Baram river in North Sarawak. 



The work is herewith finished and has resulted in the crea- 

 tion of three new genera. Out of twelve species eleven have 

 proved to be new only, one being known before. I have also 

 been able to shed new light on some critical genera. 



While working up the collections (106 specimens) the 

 specialist, Dr. E. Handschin from Switzerland, has been 

 contemporaneously working up certain material from Java 

 and Sumatra. His work has already gone in print, but 

 to prevent our work overlapping and describing the same 

 species under two separate names, Dr. Handschin has been 

 polite enough to send me a typewritten copy of his manuscript 

 and also photographs of the new species. For this proof of 

 good sense and extraordinary kindness I beg to express my 

 deeply felt gratitude.

Tuberctili distinct only on the head and the posterior seg- 

 ments of the body ; symmetrically arranged longer setae on the 

 intermediate tergites possibly point to the existence of dorsal 

 protuberances, but their contours are so vague that it seems 

 impossible to trace them with certainty on preserved material. 

 Cranida of medium size, not showing any pronounced difference 

 in size on the head or other parts of the body. Mouthparts
