Dittopternis handschini n. sp. 



Size small or médium, body slender. Antennae fîliform, sligthly 

 thickened towards the apex, reaching a little beyond the hind 

 margin of pronotum in the maie, shorter in the female. Head 

 smooth, only the vertex with some rugosities; frontal ridge slightly 

 reclinate, not quite separated from the fastigium, but sulcate near 

 the fastigium though narrow. Margins slightly widened towards 

 the clypeus, not or only slightly constricted near the ocellum. 

 Its surface impressed and rugosely punctuated, distinct throughout, 

 near the clypeus more strongly widened. Cheeks nearly smooth or 

 with some rugosities. 



Fastigium of vertex moderately sloping, forming with the frontal 

 ridge a round ed angle, not distinctly separated from the frontal 

 ridge by a distinct carina, somewhat longer than broad, pyriform, 

 somewhat narrowed in front, margins forming raised keels, its 

 surface and that of the vertex rugosely punctured, without médian 

 keel or with a blunt, low keel. Eyes globular, a little longer than 

 broad, lying in or only a little above the level of the head, interocular 

 distance little above the level of the head, twice as broad as the 

 first antennal joint. Temporal foveolae small, triangular, visible 

 from above. 



Pronotum short, constricted anteriorly ; anterior margins truncate, 

 posterior margin obtusely angulate; médian keel low, distinct, not 

 elevated, only eut by the third sulcus; latéral keels angulately bent, 

 incomplète, only indicated in the prozona and in the middle of the 

 pronotum by a small row of tubercels. First transverse sulcus 

 absent, second and third distinct, both on the dise and on the 

 lobes, third sulcus before the middle, surface of the dise finely rugose. 



Latéral lobes of pronotum deeper than long, finely punctured 

 with a small, but not shining callosity near the middle of the anterior 

 margin; lower margins broadly rounded behind, ascendant ante-
