bordered by a stout curved keel ; the sides are bordered by a stout 

 keel, inside of which are some irregular transverse keels ; there are 

 also two or three broken longitudinal keels. Abdomen closely punc- 

 tured, the base of the segments smooth and shining. The basal 

 part of the ovipositor is closely punctured, the apical smooth. The 

 four front tarsi are covered with testaceous pubescence beneath ; 

 their calcarea testaceous ; the hind tibiae keeled on the sides below.

 MESOCOMYS, gen. nov. 



Antennas 13-jointed, thickened towards the apical joint, which is 

 long, thick, becomes gradually narrowed, and is hollowed in the 

 middle below ; the flagellum sparsely pilose, the second joint four 

 times longer than thick ; they are placed not far from the mouth and 

 widely separated from the eyes. Front only slightly excavated in 

 the centre ; the vertex roundly, broadly convex. Eyes large, oval ; 

 the malar space large ; the eyes slightly converge above. Parapsidal 

 furrows narrow, distinct ; the centre of the mesonotum raised, broad, 

 rounded behind and separated from the scutellum by an irregularly 

 raised space. Scutellum large, longer than wide, rounded and 

 slightly narrowed at the apex ; at its base are two large, deep 

 foveae, widest at the base, rounded at the apex. Base of metanotum 

 trifoveate, the middle fovea the larger. Pleurae not excavated. 

 Abdominal segments not incised. Fore femora dilated, narrowed at 

 the base and apex, flattened in front ; the four hinder femora more 

 slender and longer, as are also their tibiae ; the basal joint of middle 

 tarsi greatly swollen ; the middle tibiae grooved behind, their spurs 

 much thicker than the anterior or posterior, longer, reaching to the 

 middle of metatarsus. The sub-marginal vein long, reaching to the 

 middle, its apical third curved downwards, thickened and in front 

 thickly margined with longish hair ; marginal vein short, not one- 

 fourth of the length of the sub-marginal ; radius thick, curved, cleft 

 at the apex, the upper fork short and curved, the lower straight and 

 oblique. Clypeus furrowed in the centre, the furrow widest at the 

 apex. Occiput transverse in the middle, the sides obliquely rounded. 



I am not quite certain as to the exact systematic position of this 

 genus. It should be readily known by the densely pilose, curved 

 apex of the sub-marginal vein, by the cleft apex of stiginal branch, 

 by the two large deep foveae at the base of scutellum and by the 

 three large foveae at the base of the metanotum.
