MANN: ANTS OF THE BUITISII SOLOMON ISLANDS. 301 



30. Anochetus cato Forel. 



Mitt. Mus. zool. Berlin, 1901, 2, heft 1, p. G, ^ . 



Rendova. 



The workers of a single colony taken from a rotten log, agree 

 throughout with Forel's description of this species, which is character- 

 ized by its rounded epinotal corners, the short conical projection at the 

 apex of the petiolar node and the structure of the mandil)les wliich are 

 sharply angulate at a short distance posterior to the long, terminal 

 teeth. 



The sculpture on the front of head is dense, and extends outward 

 from the frontal carinae. 



30a. Anochetus cato Forel, var. subfasciatus, var. nov. 



JVorkcr. Length 5.-5.25 mm. 



Similar to the tj-pical form in size, structure, and sculpture but black in 

 color, with the cheeks, clypeus, mandibles, legs, and a narrow apical band on 

 each gastric segment, brown. 



Female. Length 7.25 mm. 



Epinotumstrongly striate transversely; eyes not large; ocelli small. Wings 

 weakly infuscated; veins and stigma brown. Otherwise similar to the worker. 



Male. Length 4 mm. 



Head, excluding eyes as broad as long; the medial portion of vertex on each 

 side with longitudinal sulcae which diverge and extend to the ej'es. Mandibles 

 rudimentary. Antennae IS-jointed, rather thick; scape less than twice as 

 long as first flagellar joint, which is a little longer than broad; flagellar joints 

 two to six subequal, only a little more than twice as long as broad; remaining 

 joints, except the terminal, subequal; terminal joint shorter than the two 

 preceding together; conical. Prothorax evenlj^ rounded at front and sides, 

 its disc not very convex. Scutellmn transverse. Epinotum convex; the 

 base rounding into the short declivity. Petiolar node, in profile, wedge- 

 shaped; thin and narrow above; seen from tjie front, not produced above, 

 but evenly rounded; anterior surface concave; narrowly margined at sides. 

 Pygidimn acuminate apically. 



Somewhat shining. Head and thorax evenly, rather coarsely punctate. 

 Epinotum rugose. Node and gaster more sparsely punctate.
