wheeler: the ants of borneo. S3 



tooth. Postpetiole broader than the petiole, longer than broad, scarcely 

 broader behind than in front, elliptical, with convex lateral and dorsal surfaces. 



Shining; mandibles with a few minute, scattered punctures; head with the 

 cheeks and anterior -g- above subopaque, longitudinally rugulose and sparsely 

 serially punctate; occiput and lower surface coarsely and sparsely punctate 

 and shining. Thorax above smooth, with small, scattered, piligerous punc- 

 tures; sides of thorax subopaque and densely punctate; extreme base of first 

 gastric segment sharply striate; remainder of body smooth and shining, with 

 indistinct, scattered, piligerous punctures. 



Hairs pale, sparse, of unequal length, erect or reclinate; on the appendages 

 shorter and more appressed. 



Dark castaneous brown; mandibles, tips of scapes, funiculi, trochanters, 

 knees, tibiae and tarsi red. 



Described from four specimens taken at Kuching (John Hewitt). 



This species resembles V. ohloncja siibsp. laevithorax Emery in 

 sculpture, but is much smaller, with narrower head, broader mandibles 

 and longer petiole and postpetiole, and is quite different from any of 

 the numerous other species of Vollenhovia recently described by 

 Emery, Forel, and Viehmeyer. The genus is difficult, so that the 

 limits of the subspecies and varieties are still to be established on the 

 basis of much more material than has been collected heretofore. 



*93a. Vollenhovia banksi Forel subsp. kuchingensis, subsp. nov. 

 Worker,. Length 1.8-2 mm. 



Differing from the typical form from the Philippines in its darker 

 color, the body, femora, and tibiae being dark brown. The meso- 

 epinotal impression is %asible, though very feeble ; the epinotum has a 

 minute denticle on each side, the antennal scapes are a little shorter 

 and the eyes a little further forward on the head. 



Female (dealated). Length nearly 3 mm. 



Resembling the worker, but the rugae on the head are coarser, more un- 

 dulating, with finely punctate interrugal spaces. The thorax above is coarsely 

 and rather densely punctate, the pronotum somewhat reticulatcly rugose, the 

 mesonotum smooth in the middle in front, longitudinally rugulose behind, 

 the mesopleurae rather smooth and shining in the middle. The epinotum is 

 coarsely reticulately rugose, the concavity of the declivity transversely rugose; 

 the petiole and postpetiole above coarsely foveolate. The tips of the anten- 

 nal scapes reach onlj^ a little beyond the median transverse diameter of the 

 head.
