MERANOPLrS. — TEIGLTPHOTHEIX. 171 



and both nodes oE pedicel above coarsely sculptured, rugose ; sides 

 of the thorax punctured ; metauotum smooth and shining ; abdo- 

 men smooth, highly polished. Head a A'ery little longer than 

 broad, and as broad in front as posteriorly ; mandibles narrow, 

 obscm-ely striate ; clypeus depressed, not convex, smooth in the 

 middle ; autennal gi'ooves very deep and smooth within ; antennte 

 short and stout. Thorax: the pro-raesonotal shield, seen from 

 above, almost semicircular, armed with six stout spinous teeth, 

 the prouotal portion much wider than long ; metanotum as in 

 M. hicohr, smooth, slightly concave, biearinate, the carin?e ending 

 above in slender spines pointing backwards ; legs as in M. hicohr. 

 Pedicel : the 1st node cuneiform or cone-shaped, obliquely trun- 

 cate above, the 2ud node globose ; abdomen broadly cordate, convex, 

 remarkably smooth and shining. 



Length, ^ 3'5 to nearly 4 mm. 



Hah. Throughout Burma and Tenasserim up to 5000 feet 

 elevation {Feu. Bingham). 



Emery gives the abdomen as black, but in no specimen that I 

 procured is it more than a dark chestnut-brown. The shape of 

 the thorax is very distinctive in this species.

 Triglypliotbrix, Forel,Ann.Soc.Ent.£el(/e,xxxiy (1890), C. R. p.cvi. 



Type, T. ivalshi, Forel, from India. 



Range. Ethiopian and Indo-Malayan regions. 

 ^ . Resembles the ^ of the genus Tetramoriam, Mayr, but is 

 always shorter and more stoutly built. It can be recognized at once 

 by its peculiar woolly appearance, arising from nearly all the hairs 

 being trifid above the base. Mandibles and clypeus as in Tetra- 

 moriivin ; antennae * 12-jointed, the club of the llagellum of three 

 unequal joints ; antennal carinae long, wide apart at base and 

 divergent, bordering the antennal groove above the eyes, which 

 groove is longitudinally divided by a low but distinct carina for 

 the reception, on one side of the latter, of the scape, and, on the 

 other, of the flagellum when folded. Thorax somewhat as in 

 Tetraniorium, with metanotal spines and metasfcernal teeth, the 

 thoracic sutui-es, however, more or less obsolete ; legs somewhat 

 short and stout. Pedicel rather short, the nodes broad and a little 

 flat above, the 1st node shortly petiolate anteriorly ; abdomen 

 oval. 



2 . Very closely resembles the ^ . but larger ; fore wing with a 

 single open radial cell. The transverse nervure joins the cubital 

 nervure at the point where it forks. 



In one Indian species 10-jointed.
