MANN: ANTS OF THE KHUISII SOLOMON ISLANDS. 347 



witli five sliort, subequal teeth. Clypcas moderatelj' conve.x, bluntly carina te 

 at iiiiddle; anterior border almost straight at middle. Antennal scrobes well 

 defined, extending beyond eyes, the carinae bordering the inner sides somewhat 

 creniilate and narrow but (^onspieuouslj' stronger than the carinae of front and

vertex. Antennae short and thick; scapes extending less than three fourths 

 the distance to occipital corners; fimicular joints two to eight twice as broad 

 as long; terminal joint about as long as the two preceding joints. Eyes not 

 very convex, located in front of sides of head a little behind the middle. Thorax 

 robust, the sides nearly straight; all sutures obsolete; prothorax margined at 

 sides, with angulate humeri. Epinotum with base and declivity rounding 

 into each other, the latter flat: spines acute, curving downward, moderatel}^ 

 divergent, a little shorter than their distance at base. Petiolar node higher 

 than long, with short pedicel which is angulate at anterior corners. From 

 above globose, as long as broad. Postpetiole broader than petiole and broader 

 than long. 



Subopaque. Mandibles punctate and striate, the striae stronger basally. 

 Cl^-peus with two carinae lateral to the median one. Antennal scrobes opaque 

 and verj^ densely punctate; head finely and reticulately carinate, the inter- 

 spaces punctate and feebly shining. Thorax and epinotum densely punctate. 

 Petiole and postpetiole rugulose and more shining. First gastric segment 

 uniformly, shallowly, and very densely punctate and opaque; terminal seg- 

 ments punctulate and rather more shining. Antennae punctate. Legs shin- 

 ing. 



Pilosity erect, sparse and white in color. 



Color ferruginous. Legs lighter. 



Three Sisters: Malapaina (Type-locality). Santa Anna. 



The workers on w'hich the description is based agree closely with 

 Emery's description of the typical form from Berlinhafen, New- 

 Guinea, except in the lighter color. The epinotal spines in my speci- 

 mens are proportionately longer than shown in the drawing of scrobi- 

 ferum (Term, fuzet., 1897, 20, pi. 15, fig. 31). • Typc.— M. C. Z. 9,177. 



As Emer}^ has pointed out, this curious species approaches Calypto- 

 myrmex in the structure of the antennal scrobes, the shortly peduncu- 

 late petiole, and the short and thick antennae.
