Is thus to some extent a connecting link between the Myrmicinge, and 

 ihe Cnjptocerinre. The workers have a tendency to roll themselves 

 Into a ball, from this fact, it seems to me, that Mero-nopluz is de- 

 scended from the Myi-miiina- through the type Te^rcmtovinm. The 

 genus Ti' iyh/pho Hi rix also resembles the genus (Jahipiomyrmex (Emery ) ■

 single open radial cell. The transverse nervure joins the cubiud 

 mervure at the point where it forks.

$ Length 1*9 to 2'4 mm. The mandibles armed anteriorly wil 

 three distinct teeth and posteriorly with three others, small and 

 indistinct, shining, with some coarse punctures and a few short, 

 coarse striures. Frontal area and groove absent. Epistome coarsely 

 wrinkled. The whole head lustreless, very coarsely and deeply reticulate 

 (at the sides and beneath) or longitudinally rugose-reticulate, except 

 the bottom of the double antenna! groove, which is shining and finely 

 rugose-reticulate. The head is in shape a trapeze, with only slight iv 

 diverging sides, broader behind than in front, broadly and feebly 

 notched posteriorly, slightly longer than broad. Thorax very short 

 and very stout, rather shorter than the head, its back very faintly 

 edged, but with two well-marked " shoulders " anteriorly, feebly con- 

 vex. Basal urea of the metanotum somewhat sloping. The pronotum 

 is as broad as two-thirds the length of the thorax. Metanotai spines 

 three-cornered, broad at the base, shorter than the distance between 

 them. The sloping area of the metanotum shining, with two or three 

 marked transverse wrinkles, bounded by small ridges anteriorly and 

 laterally. The two small lamelliform metasternal teeth are conti- 

 nuations of this ridge. All the rest of the thorax and the pedicle 

 (except the petiole of the first knot) deeply and coarsely reticulated 

 and lustreless. The two knots of the pedicle are of the same length., 

 breadth, and rounded form, they are twice as broad as long; the first 

 is a trifle higher than the second. Abdomen a short oval; the anterior 

 half of first segment is lustreless, densely striate longitudinally. 

 The striures are frequently crossed by short transverse ridges, which 

 fxtend from one side to the other, and which represent a hair-bearing 



biculatiott, oi ' whieli the posterior side has disappeared. The re- 

 inaindei of the abdomen and the feet are smooth and shining: the
