Additional remarks on Dolichoprosopis maculatus, Rits
Notes from the Leyden Museum , Volume 11 - Issue 4 p. 222- 222
The description of the above named Longicorn has been drawn up from a unique, rather old ♀ specimen in the collection of the Leyden Museum, originating from Halmaheira. I possessed already for some time a fine ♀ example from the same locality, which agrees exactly with the type specimen, however, being quite fresh, the rufous colour of the elytra is much darker and the elytral spots are chalky-white not dirty-white. More recently I got a ♂ 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 abundantly 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 circumstances I abstain from proposing now a name for it, which it surely deserves, if it turns out to be a local form.
