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.
