222 DOLICHOPROSOPIS MACULATUS. 



NOTE XLIV. 



ADDITIONAL REMARKS 

 ON DOLICHOPROSOPIS MACULATUS, RITS. 



J. R. H. NEERVOORT van de POLL. 



The description of the above named Longicorn has been 

 drawn up from a unique, rather old 9 specimen in the 

 collection of the Leyden Museum , originating from Hal- 

 maheira. I possessed already for some time a fine V exam- 

 ple from the same locality , which agrees exactly with the 

 type specimen , however , being quite fresh , the rufous co- 

 lour of the elytra is much darker and the elytral spots 

 are chalky-white not dirty-white. More recently I got a 

 cf specimen from Batjan, which in general appearance 

 recedes so largely from the typical form , that it might be 

 easily mistaken for a distinct species. The elytra, instead 

 of being rufous-brown , are entirely clothed with a pale 

 bluish-grey pile , on this ground colour the chalky-white 

 spots are still perfectly contrasting. I failed to find this 

 colour-difference accompanied by any structural character, 

 of course besides the sexual peculiarities of the longer 

 antennae and the thicker scape. Such an important change 

 in colour of the covering pile is not to be met with abun- 

 dantly and it remains to be elucidated whether this variety 

 must be regarded as a geographical form peculiar to Batjan , 

 or simply as a sexual peculiarity 1 ). Under these circum- 

 stances I abstain from proposing now a name for it, which 

 it surely deserves , if it turns out to be a local form. 



1) The possibility of its being a sexual difference is not excluded , I may ca 

 to mind the enormous differences existing between the sexes of many species o i 

 Dorcadion.
