King and Queen. 



Similar to the above, but sliglitly darker. Both have the antennae mutilated, 

 ten or eleven joints only remaining. The abdomen of the latter is about 1 mm. 

 longer and a little wider than that of the alate form. 



Biologii : The king and queen described above were taken in a rotten log 

 lying in dense tropical forest in the type locality. Witli them were found young 

 larvae, nymphae of the first form, and soldiers, numbering in all several tliou- 

 sand individuals, of which soldiers comprised about 1 per cent. There were no 

 eggs or very young larvae in the colony. 



A portion of the log, containing soldiers and nymphae of the first form, 

 was placed in a jar and kept moist from date of capture on 22nd May until 

 2nd August following, when the alate forms, here described, emerged. 



Identification: By comparison of soldiers and nymphae with co-types of 

 these castes.

Head (Fig. 32) very long, broadly rounded behind, curved on the sides, 

 widest across the middle and sloping in to the base of the mandibles; front 

 slightly rugose, sloping to the base of the elypeus. "Y" suture distinct. Labrum

 2nd, narrowed in the middle, swollen at the apex, 2nd nearly quadrate, these 

 two joints paler than others, 3rd as long and wide at the apes as 2nd. narrower 

 at base, 4th smallest of all, 5th a little longer and wider than 4th, 6th-16th in- 

 creasing successively in length and decreasing in width at the base, 17th much 

 shorter than 16th, oval. Gula long and narrow, about one-ninth as wide as 

 head. Mandibles (Fig. 34). 



Thorax : Pronotum very large, much wider than long, not quite as wide as 

 head, anterior margin slightly concave and bent up, sides rounded, posterior 

 margin slightly concave, margin all lound darker than : est of surface, darkest
