5 minor. — L. 7 mm. 



Kmargination of clyi)ous wider and not so deep. The 

 concave l)asal surtaco of epinotiim longer in proportion. 

 The cpinotum is often entirely dull rod, and there i.s a small

Emargination of clypeus as in 5 major. ilead rather 

 wider than thorax. Prunofuin very slightly shouldered. 

 Basal surface of e})iiiotum straight, and only one-third as 

 long as tiio declivous surface. Sculpture as in 5 niajor, 

 «'.\cept that tlio basal surface of epinoiuin is more reticulate 

 than striate. 



Colour as in 5 nmjor, exee[)t that the red extends from 

 the sides across the top of the liasal surface of epinotum, and

From the description of the 5 niinor it will be seen that 

 this ant very closely resembles the C. {Myrmosaga) deuitzii, 

 Forel, from the Congo, described in the Bull. Soc. Vaud.Sci. 

 nat. 18bG ( 5 niinor). 



No. 85. Poli/rhachis comata^ sp. n., group gnen'ni. 



5 . — L. 5 mm. 



Mandibles siiining, densely striate (more coarsely than in 

 f/uerini), with'4(?5) teeth. Clypeus subcarinate, the antciiur 

 margin |iroduced in a short lobe (shorter and broader than in 

 yuerini), with a concave border and five small teeth. Frontal 

 carintC short, wider apart than the distance from each to the 

 sides of the head, fairly divergent, and reaching the anteiior 

 margin of the eyes. The latter are placed near the posterior 

 border of head and are not very prominent. Head slightly 

 longer than broad, broader behind than in front, slightlv 

 convex behin<l, sides convex. I'rouotum broader in front, 

 the sides rectilineal and bordered ; the teeth at the anterior 

 angles of medium length, about twice as long as their width 

 at base. Pro-mesonotal suture distinct, ineso-epinotal less so. 

 Epinotum with two spines as long as the width between 

 them ; declivous longer than basal surface. Pedicel with 

 long curved spines, like buffalo's horns, thick at base, en- 

 circling the first segment of gaster. The first segment of 

 the latter more than twice as lojig as the rest of the gaster, 

 the whole rounded, about as broad as long.
