GNAPHALORYX PERFORATUS. 39 NOTE VIII. FOUR NEW SPECIES OF EXOTIC COLEOPTERA. DESCRIBES BY C. RITSEMA Cz. Liwcnnidae» Gnaphaloryx perforatus , n. sp. cf. (Plate 3, fig. 1, la and \h). Length with mandibles 27,5 mm. , that of the left man-dible (which is a little longer than the right one) 8 mm. — Ground-color black, covered all over (with the exception however of the tip, the inner margin and the undersurface of the mandibles, the tip of the cephalic horn, and the clypeus) with a delicate brownish grey crust which does not hide the punctuation. The uppersurface of the mandibles , the margins of the thorax and of the elytra , and the scu-tellum , are densely beset with pale dirty yellow scales ; moreover very small scales are present on the whole un-dersurface, whereas a small number of larger scales are arranged in ten longitudinal rows on the elytra. The tibiae seem to be sharply edged which is caused by rows of densely set erect scales The punctuation of the head is quite similar to that of the thorax ; the punctures are round and rather large , very shallow and provided with a point in the centre. The punctures on the elytra are smaller, deeper and more regularly distributed over the surface. Notes from tlae Leyden IMuseum , V ol. "VII.
