frontal lobos; c-lypeus in front, armed with six stout denticles. Mandibles a 

 little less than two thirds as long as head, the thickened basal portion with five 

 teeth, the apical three bifid; the slenilor apical portion with one small denticle 

 and two minute ones near apex. Frontal lobes converfjent, the carinae short, 

 feeble, and diverging behind. Scape short, extending less than two thirds the 



distance to the occipital corners; all 

 the funicular joints except the first 

 and apical distinctly transverse; 

 apical joint nearly twice as long as 

 broad. Eye distinct, but minute, 

 located at sides of head posterior to 

 the middle. Thoracic dorsum and 

 epinotum flat. Prothorax a little 

 longer than broad, evenly rounded 

 in front; sides parallel; disc at 

 middle with a very feeble longitu- 

 dinal carina. Promesonotal suture 

 strongly impressed. Mesonotum 

 nearly twice as broad as long, sides 

 evenly rounded. Epinotum one 

 and one third times longer than 

 broad, broadest behind, sides con- 

 vex at anterior half, then straight; 

 declivity transverse, strongly mar- 

 gined at sides, disc shallowly con- 

 cave. Petiole narrower than first 

 gastric segment ; from above a little 

 Ijiroader than long, rounded, in front, wdth nearly straight sides; from the side 

 slightly longer than deep; ventral process small, rounded in profile. Gaster 

 slender. Legs stout. 



Sublucid throughout. Mandibles with short coarse rugae and stiff erect 

 hairs. Scapes, head, thorax, and petiole densely granulose, the head more so 

 than the rest, with short, semierect pilosity. Petiole, gaster, metathoracic 

 pleurae, and legs punctate, similar to, but more shallow than, the rest of the 

 body; the pilosity of the gaster becoming dense toward apex. 

 Color ruf otestaceous ; the head a little darker; pilosity yellowish white.

 Mann. Worker. Front view of head. 



Described from workers taken with larvae and pupae from small 

 colonies nesting in humid forests beneath stones, on Ysabel (Fulakora 

 T^-pe-locality) , and Malaita (Auki) and from Tulagi, Florida, and 

 Wai-ai, San Cristoval. The specimens from Tulagi and Wai-ai are 

 darker than the others. Type. — M. C. Z. 9,152. 



Pupae entirely naked. 



The larva is covered with fine, w'hite, erect hairs and is very similar to
