2. Cerapachys (Cerapachys) majusculus, sp. nov. 



Worker. Length 4.50 mm. 



Head a fourth longer than broad, as broad in front as behind, with moder- 

 ately convex sides and shallowly and not broadly concave posterior borders. 

 Mandibles finely denticulate. Carinae of cheeks prominent, armed with three 

 widely separated blunt teeth. Frontal carinae prominent and approximated, 

 broadly rounded in profile. Antennal scapes extending a little beyond the 

 posterior border of eye. Funicular joints 2-10 transverse; terminal joint as 

 long as the five preceding joints together. Eyes convex, situated at sides of 

 head a little in front of middle. Thorax subquadrate, a little more than twice 

 as long as broad, and very slightly narrowed at mesonotal region; in profile 

 moderately convex. Epinotal declivity flat, submargined laterally and above. 

 Petiole broader than long, as broad in front as behind; in profile higher than 

 long, with a stout anteroventral tooth. Postpetiole broader than petiole, 

 broader than long, and slightly narrowed in front. First gastric segment a 

 fourth longer than broad. Pygidium flat discally, its border spinulose. 



Shining. Mandibles with sparse, coarse punctures. Head and thorax with 

 moderately strong, scattered piligerous punctures. Petiole and postpetiole 

 with more abundant and much coarser punctures. Gaster finely punctate; 

 the apical borders of each segment and the margins of the pygidium with 

 coarse, shallow punctures. 



Fine erect hairs moderately abundant on head, body, and appendages. 



Black; gaster brownish; appendages dark reddish brown. 



Viti Levu: Nadarivatu. 



Described from a number of workers, from several colonies taken 

 with larvae and pupae beneath stones. Type. — M. C. Z. 8,682. 



Key to Fijian Species. 



1. Length 4.5 mm. Punctation of head and thorax fine, that of petiole 

 and postpetiole stronger, but widely separated viajusculus Mann 



Length 3 mm. Punctation of head and thorax coarse, that of petiole very 

 coarse and dense, giving these parts a subrugose appearance 2. 



2. Dorsima of thorax at middle with fine punctures, sparsely distributed 

 and much finer than those at the sides of dorsmn and on pleurae. 



vitiensis Mann 



Dorsum of thorax at middle with coarse punctures similar to those of 



pleurae vitiensis subsp. sculpturatus Mann 



3. Cerapachys (Syscia) cryptus, sp. nov. Fig. 1. 



Worker. Length 4 mm. 



Head a fourth longer than broad, as broad in front as behind, sides feebly 

 convex, posterior border shaUowly concave. Mandibles elongate triangular.
