244 A. Forel — Indian Ants of the Indian Museum, Galcutta. [Ko. 3, 



obtuse angle. From the middle of the mesonotum it descends again as 

 far as the deep meso-raetanotal strangulation. The middle of this de- 

 scending surface is interrupted by the two protuberant stigmas. The 

 basal surface of the metanotum is very abruptly ascending, hardly 

 arched, and terminated behind by a transverse nearly rectilinear edge, 

 which forms with the declivous surface a right or nearly acute angle. 

 The declivous surface of the metanotum is plane above and concave 

 below. 



Viewed above, the pronotum is flattened, widened, trapeziform ; the 

 mesonotum is elongate and has a strong longitudinal impressed line with 

 two edging blunt elevations in the middle of its sides ; the basal surface 

 of the metanotum is rectangular, longer than broad. 



Scale raised, hardly inclined, moderately thick, evenly convex in 

 front and behind, with the upper edge transverse and slightly rounded. 

 The abdomen of the sole specimen is deformed. 



Mandibles smooth aud shining with very scattered puncture. . The 

 whole body shining, especially the head. The head very delicately reti- 

 culate at the sides. On the anterior surface of the head, this sculpture 

 passes into a very delicate scattered puncture, which replaces the 

 reticulations. Thorax more or less delicately reticulate, except the 

 declivous surface of the metanotum, which is smooth. Scale delicately 

 reticulate or punctate. Abdomen with very delicate scattered puncture. 

 No erect hairs. An extremely fine and much applied pubescence is scat- 

 tered over the whole body, especially on the abdomen, on the scapi, and 

 on the legs, where it forms a slight and delicate down. 



Uniformly dark brownish or reddish yellow. Antennae and legs 

 clearer. 



Gizzard (proventriculus) without sepals, of the same shape as in 

 the other species of the genus DolicJioderus, for instance, very like that 

 of D. hispinosus. I softened the abdomen in water, and was thus 

 enabled to dissect out that organ without destroying the specimen. 

 Sibsagar. 



N. B. I have found the gizzard of D. maricd, Forel, very like that of 

 D. 4i-punctatus of Europe. 



III. Subfamily Poneridae. 



Genus Ponera. 



18. Ponera leeuwenhceki, n. sp., ^. Resembles a little the P. insu- 

 lana, Mayr, and P. tesserinoda, Mayr, but is quite distinct. Length : 7. 5 — 8 

 millims. Mandibles shorter and broader than in P. tesserinoda, strongly 

 striate, with scattered puncture above the striation, armed with 7 teeth.
