180 A. Forel — Indian Ants of the Indian Museuin, Calcutta. [No. 3, 



Mesonotmn with a deep transverse impression, which is nearly as 

 deep as the meso-metanotal groove. Basal surface of the metanotum 

 narrow, with a very distinct, abruptly edged longitudinal channel in the 

 middle. Spines of the metanotum of moderate size, divergent, near one 

 another at the base. The nodes of the petiole have the usual form ; the 

 second node rounded, without lateral conuli. Antennas and legs rather 

 elongate. 



Head coarsely and longitudinally striated in the middle ; striate- 

 rugose, then reticulate-rugose at the sides, very coarsely rugose-reti- 

 culate at the posterior angles (like P. latinoda). Frontal area and 

 middle of the clypeus nearly smooth. Thorax wrinkled and rugose, 

 moderately shining. The sides of the mesonotum and metanotum, as 

 also the declivous (posterior) surface of the metanotum finely reticulate- 

 punctured and opaque. Nodes of the petiole finely reticulate, nearly 

 opaque. The base of the abdomen very delicately reticulate ; the rest 

 smooth and shining with some scattered punctures, with a hair in each 

 point. 



Head and abdomen sprinkled moderately with erect hairs. A few 

 scattered erect hairs on the thorax and the femora. The tibise and 

 scapi without erect hairs, only with a delicate quite applied pubescence. 

 The body nearly without applied pubescence. 



Dark ferruginous-red. The posterior three-fourths of the head, the 

 scapi, and the abdomen (its base excepted) dark chestnut-brown. 



This species is easily to be distinguished from the Ph. latinoda by 

 its smaller size, its tibias and scapi without erect hairs, the nodes of 

 its petiole, etc. ; from the Fh. indica by its carinate clypeus, its more 

 emarginate head with the posterior angles coarsely reticulate-rugose, etc. 

 The closely allied Ph. javana has very abundant erect hairs on the loo's 

 and on the antennae, the metanotal spines much removed from another 

 at the base, the clypeus without carina, etc. 



22. Pheidole wood-masoni, n. sp. 



I dedicate this pretty little new species to Prof. J. Wood-Mason, 

 who has been so kind as to send it to me with the others noticed in this 

 paper. 



%. Length 2.6 millims. Head elongate, rectangular, slightly 

 emarginate behind. Eyes very minute, each compounded of about 20 

 facets, situated at the anterior quarter of the head. Antennae very 

 short ; scapi of the antennae as long as half the breadth of the head, 

 either as long as two-fifths of the length of the head (without mandi- 

 bles). Antennse 12-jointed, with very large club; the last joint as 

 long as the two precedent together. Joints 2 — 6 of the funiculus twice 

 as broad as long. Mandibles smooth, shining, with very scattered punc-
