wheeler: the ants of borneo. 145 



as Atopomyrmex ceylonicus, has recently been placed by Forel in the 

 genus Leptothorax. As I cannot agree with this allocation and 

 as the species cannot be left in Atopula, I have coined a new generic 

 name, Paratopula.

*21. Myrmoteras bakeri, sp. nov. 



Female. Length nearly 4 mm. 



Very similar to M. donisthorpei Wheeler, but differing in the following 

 characters: the five large teeth along the apical half of the mandibles are 

 distinctly longer and stouter, though alternating with shorter teeth as in 

 donisthorpei, whereas the denticles on the basal half are very small and almost 

 obsolete; the frontal carinae are somewhat further apart; the lateral lobes 

 of the head just behind the eyes are more acutely angular; the petiolar node 

 is much more compressed anteroposteriorly so that its upper border is trans- 

 verse and rather sharp; the middle and hind tibiae are less strongly swollen 

 in the middle and the sculpture and color are different. The head is very 

 smooth and shining like the remainder of the body, and the insect is honey- 

 yellow, with the mandibles, except their brownish teeth, the femora and tarsi 

 paler, whitish yellow. The middle portion of the first gastric segment and the 

 bases of the succeeding segments are brownish. The pilosity and wing- 

 venation are as in donisthorpei, but the erect hairs on the scapes, body and legs 

 are somewhat coarser and more bristly. 



Male. Length 3 mm. 



Head through the eyes broader than long, gradually contracted and rounded 

 behind, without the peculiar lobular eminences of the female, to the concave 

 and marginate occipital border. Eyes large, but placed far forward, so that 

 the cheeks are very short. Ocelli small. Mandibles very small, vestigial, 

 bluntly pointed, edentate. Clypeus, frontal carinae, and antennae much as 

 in the female, except that the antennae are 13-jointed. Thorax, gaster, and 

 legs as in the female; middle and hind tibiae less incrassated, petiolar node 

 thicker and much blunter above. Genital appendages small, exserted, super- 

 ficially like those of Prenolepis. Wings as in the female, with the same 

 peculiar venation.
