POLYUHACH1S. 405 



each side of the node is a short laterally pointed acute tooth or 

 spine ; abdomen very massive, broadly oval. 



$ . Similar, somewhat larger, with the inesonotum very long, 

 convex above and gibbous ; thoracic and pedicel spines shorter and 

 thicker : wings flavo-hyaline, nervures brown. 



Length, $ 9-5-10-5; $ 11-12 mm. 



Hab. Bengal, Sikhim (Moller): Kanara ( Wroughton) ; Travan- 

 core (Ferguson) ; Ceylon (Yerbury) ; Burma, Tenasserim (Bingliam) ; 

 extending down to the Malayan subregion. 



A common species in Burma.

Polyrhachis mayri, race intermedia, Forel, Jour. As. Soc. Seng. Iv 

 (1886), p. 242, ; Jour. Bomb. N. H. Soc. viii (1893), p. 20, $ . 



. Very similar to P. mayri and P. proxima. Resembles the 

 former in having the thorax narrower posteriorly than in front, 

 and the latter in wanting the transverse carina bordering the 

 basal portion o the metanotum, in the closely approximate 

 antennal carinae, and the bimucronate lateral spines on the pedicel. 

 Differs from both in having greyish, not golden pubescence very 

 sparse, not hiding the sculpture ; this gives it quite a different 

 appearance. 



Length, 8-9 mm. 



Hab. Assam (Smythies) ; Burma : Myitkyina, Bhamo and the 

 Ruby Mines (Bingham). 



I 'am not quite certain whether I have identified this species 

 correctly. I have not met with it further south in Burma than 

 the Ruby Mines district.

p. loo, $ ; Forel, Jour. Bomb. N. H. Soc. viii (1893), p. 20, . 



. Closely resembles P. mayri, being black and covered with 

 similar dense golden shining pubescence, which hides the sculp- 

 ture ; but besides the bimucrouate lateral spines on the pedicel, 

 this species is shorter than P. mayri, with a proportionately wider 

 thorax posteriorly, and with the antennal carinse very much closer . 

 together. 



$ . Resembles $ of P. mayri, but the mesonotum and scutellum 

 are still more gibbous and raised than in that species. 



Length, $ 89 ; $ 10 mm. 



Hab. Burma (Bingham) ; Ceylon (Yerbury, Green); Malacca 

 extending to Java.
