126 COLLEMBOLA FROM NORTHERN SARAWAK. 



Antennae and legs normally hairy. The distal end of 

 manubrium near the dentes with a row of down-hanging, 

 very strong feather-shaped setae; dentes also with long, thin, 

 feather- shaped setae, but also with some odd, very stiff, 

 pointed, serrated ones. Near mucrones there are two or three 

 double-contoured very strong down-hanging setae. 



11. Bromacanthus handschini n. sp. 



The colour in specimens pi'e.served in alcohol nearly pure 

 white with some blue-pigmented distal dots on Ant. Ill, Ant. 

 IV, entirely bluish. 



Length of body 2 mm. 



Locality. About thirty specimens from Mt. Dulit, 4000 feet, 

 and a single one from the same mountain, 3000 feet. They 

 lived on bushes and ^vere g(3t by shaking the branches over 

 an umbrella (Mjoberg). 



Remarks. Wriien examining this species I first thought to 

 have to do with a species of tlie genus ParoncUa, but the 

 peculiar shape and distribution of the dental spines, the 

 mysterious femoral organ and tlie presejice of antennal 

 sensitive organs necessitate the creation of a new genus. A 

 deciding factor should have been the secondary articulation of 

 the apical antennal joint, Init 1 am not in the position to say 

 anything definite concerning this characteristic. Only very 

 few specimens ^v•ith antennae in fact are accessible and in a 

 couple of those I believe I can see distinct annulation on 

 Ant. IV., but in anotlier specimen the picture is indistinct. 



It deserves to be mentioned that in several individuals there 

 is a peculiar anomaly in the antennae : Ant. Ill is either 

 entirely missing or at least strongly reduced. 



In the former case only the longer, not annulated basal part 

 of Ant. IV gives the impression of a joint of its own. Also 

 the supposed joint-suture toM'ards Ant. IV is very indistinct 

 and the segment itself has no sensitive organs at all. 



12. Cyphoderes serratus Schott. 



In Dr. Mjoberg 's collection there are five specimens from 

 Mt. Dulit of a form which I must regard as identical with the 

 species described by me from Australia under the above name. 

 A. detailed comparison with Australian individuals shows no 

 differences. The species is so characteristic as to preclude 

 any mistake.
