A very remarkable Longicorn from Sumatra
Some years ago, taking care of the entomological material, collected by Mr. Edw. Jacobson, I saw among the Coleoptera a very beautiful Longicorn, unknown to Messrs Ritsema and Veth. After the dead of Dr. H. J. Veth, all his Coleoptera, among which also the material of Mr. Jacobson, turned back to the Leiden Museum of Natural History. Immediately I looked for the beautiful Longicorn, but I could find neither the specimen nor the figures, which I painted in water-colours in behalf of Dr. Veth. Those figures had been sent to several foreign specialists, our unique specimen being probably a representative of a new genus and species. After a year I found the Longicorn (Lamüd) and now I will give without delay the following description, abstaining of a comparison with any one of the hitherto described genera and species, as this species is very aberrant. So the relationship to other genera provisionally must remain a puzzle. Capitocrassus castaneus, nov. gen., nov. spec. Antennae: 12-jointed, reaching to the end of abdomen, covered by a grayish redbrown felt, darker brown to the end of antennae. Underside provided by short hairs. The scape of the antennae 5,5 m.m. long and 1,7 m.m. broad, without the short hairs of the other joints. The second joint very small; the third joint 7,5 m.m. long and narrower than the scape; the 4th joint 5 m.m. long; the 5th—11th slightly decreasing in length, and the apical joint, which is pointed at the tip, very short and grown together with the 11th joint. Through this the antennae seem to be 11-jointed. Head: very large; seen frontally, longer than broad with rounded
