120 COLLEMBOLA FROM NORTHERN SARAWAK. 



Legs with scattered blue spots on the upper joints, tibiae 

 entirely blue. 



Length of body 3, 5—4,00 mm. 



Locality. Mt. Murud, 6000 feet, 3 specimens. 



Remarks. The species comes nearest to Wahlgren's D. 

 meruensis. This has also the dental spines arranged in 

 three parallel rows, but not quite so regularly, and the 

 external spines are not so big and are less curved than in 

 the Bornean species. 



Tribus Paronellini. 



Quite recently Dr. E. Handschin has proposed to split up 

 the species of my genus Paronella into four genera. His step 

 seems to me justified and offers no considerable difficulties in 

 placing the species known up to now. The difference between 

 Paronella s. str. and Aphysa, however, appears a bit too vague 

 to adhere to strictly in future if decided only by the number of 

 mucronal teeth. Perhaps some additional characters could 

 be discovered in the shape and structure of the scales. 

 x\t present I have not sufficient material to enable me to 

 draw any definite conclusions. I hope, however, to be able 

 to ventilate the question more in detail, when working up a 

 collection from Gamer un. Here it might only be mentioned 

 that a typical Paronella species, P. nigromaculata has thin, 

 broad, in the free end rounded scales, with very fine striation 

 and perhaps the species has this character in common vdth 

 other true Paronella species. In all other forms of the group 

 the scales are narrow, pointed, densely pubescent, approach- 

 ing scuated setae. 



Also the following points of view may be referred to here. 



Dr. Handschin asks me in a letter if in reality those 

 described by me as Pericrypta mjohergi are covered by scales. 

 If so it would be a welcome guest among the forms included 

 in the new genus Pseudoparonella. On account of his inquiry 

 I have thoroughly re-examined twelve specimens, but failed 

 to discover a single scale. I should hke to add that I do not 

 consider it advisable any longer to maintain Ritter's generic 

 name Pericrypta for the Australian species as this forms a 

 confusion of two different genera. I therefore propose to 

 change it to Paronellides, which name seems to express 

 adequately the position of the Australian form.
