and slightly paler lateral and anterior portions , head antennae , legs 

 and anal somite nearly white. 



Head hairy; antennae long, much longer than the head and ros- 

 trum; the 2 nd segment twice as long as the 3r d , the 3 rd , 4 th and 

 5 th subequal in length. 



Body stout, the tuberculiform keels beginning on the 8 th segment 

 and gradually increasing in size posteriorly. 



Legs moderately long, the 2 nd segment about three times as long 

 as the 1 st and about as long as the 3 rd , the 6 th the longest. 



Number of segments 74—94. 



Length up to 40 mm., width 3. 



In the proportion of length to width this species seems to resemble 

 S. picteti of Humbert; but the latter appears to be smaller, is of a 

 reddish colour and has the 2 nd and 3 rd segments of the antennae 

 equal in length. 



One immature example that was obtained is entirely pale. 



32. Siphonorhinus angustus sp. n. 



Java: Buitenzorg. A single cf specimen. 



Resembling S. pallipes but much narrower in proportion to its length. 

 There are 104 segments. 



Length 34 mm., width less than 2 mm. 



Legs shorter than in S. pallipes, the 1 st segment being only about 

 half the length of the 2^. 



These two species are really so much alike that I am perfectly 

 prepared for fresh specimens to show that the differences pointed out 

 are merely due to individual variation. But at present there is no 

 evidence that such is the case and the analogy of other species of 

 the group lends no support to the view.
