278 bulletin: mlselm of comparative zoology. 



in profile convex above. Epinotal declivity flat, margined above and at sides. 

 Petiole subrectangular, a little broader than long, margined in front, sides 

 feebly rounded, anterior surface flat; in profile, about as long as high, rounded 

 above, ventral tooth large and triangular. First gastric segment similar in 

 shape to petiole, about a third broader; remainder of gaster less than twice as 

 long as broad. 



Mandibles sparsely punctate and shining. Head, thorax, and gaster with 

 scattered foveolate punctiu'cs, which are more abundant and largest on the 

 head, thoracic pleurae, and petiole, becoming contiguous on the metapleurae, 

 more sparse on the pronotum and gaster, and lacking on epinotal declivity. 

 The interspaces smooth and shining. Legs and antennae finely punctate and 

 sublucid. 



Head and body with fine, long, erect hairs; legs and antennae with shorter, 

 stiffer, and semierect hairs. Blades of mandibles with brush of short pile. 



Color piceous; mandibles, legs, and antennae ferruginous, tibiae partly 

 fuscous. 



Male. Length 3 mm. 



Head, excluding eyes, longer than broad, narrowly rounded behind; cheeks 

 short. Mandibles very similar to those of worker. Clypeus as in worker. 

 Antennae short, scapes club-shaped, not extending to occipital corners; funic- 

 ular joints longer than broad, gradually increasing in thickness toward apex; 

 apical joint a little longer than the two preceding together and but slightly 

 thicker than the penultimate. Eyes and ocelli large and convex. Promeso- 

 thorax in profile strongly convex, without Mayrian furrows. Mesometanotal 

 suture straight, distinctly impressed, scutellum convex. Epinotum convex, 

 without distinct base and declivity. Petiole and first gastric segment similar 

 to those of worker. Gaster thick. Genitalia prominent. 



Punctation similar to that of worker, but more feebly shining. Pilosity as 

 in worker. 



Wings deeply infuscated and densely covered with short suberect hairs. 

 Stigma dark fuscous. 



Piceous; mandibles and antennae fuscous; tibiae dark testaceous. 



Three Sisters: Malapaina (Type-locality). Ysabel: Fulakora. 



Described from several workers and males taken from a colony 

 situated in wet earth beneath a stone and from two workers found 

 running on the ground. Type. — M. C. Z. 9,151. 



The distinctly, though finely, denticulate mandibular blades and 

 the more slender antennae distinguish tcrricola from inconspicua Emery. 

 In the latter species the second funicular joint is very small; the 

 funiculus robust, with the club barely longer than the four preceding 

 joints. In terricola the club is as long as the six preceding joints.
