piligerous punctures very sparse, otherwise impunctate. Head 

 moderately elongate, truncate posteriorly. Clypeus obtusely biden- 

 tate. Mandibles quadridentate ; last joint of antenna very large, 

 nearly as long as the four preceding together. Thorax fairly elongate, 

 the meso-epinotal suture deeply impi-essed, the pro-mesonotal suture 

 obsolete, the epinotum very obtusely angulated ; the 1st joint of the 

 petiole with a very short peduncle, the node high but narrow, and 

 longer than wide ; the 2nd node subglobose, much smaller and a little 

 narrower than the 1st.

" Facies of a Solenopsis, very smooth and shining, with a few 

 piligerous punctures. . . . The carinae on the clypeus are moderately 

 prominent. The eyes are fairly small, and separated from the base of 

 the mandibles by one and a half times their own diameter. The scapes 

 do not extend back to the occipital margin. . . . The thorax is 

 elongate, compressed at the meso-epinotal suture, which is deeply 

 impressed and striated. . . . The joints of the petiole are vei-y 

 unequal. The first, seen in profile, appears pedunculated along two- 

 fifths of its length, the node cuneiform ; seen from above, the node 

 appears distinctly longer than wide, rounded in front. The 2nd joint 

 is globose, much smaller and a little narrower than the 1st."

" ^ • 2 - 5 mm. Mandibles strongly striated, tridentate. Clypeus 

 entire, strongly concave between its two carinae ; these are separate in 

 front, but nearly contiguous betw r een the frontal carinae, and are con- 

 tinued round the sides to the anterior margin. Head nearly quadrate, 

 a little longer than wide, and a little wider in front than behind ; the 

 sides feebly convex, widely concave behind. The eyes are fairly large, 

 slightly elongate, placed between the middle and the anterior third. 

 The scape does not extend back quite as far as the hind margin of the 

 head; 3rd-8th joints of the flagellum wider than long, the club not 

 very thick, the penultimate joint only a little larger than the preceding. 

 Pro-mesonotum convex, without a distinct suture, the constriction a 

 little feebler than in gracillimum. Epinotum convex, the dorsum 

 merging by a barely perceptible curve into the declivity ; the dorsum 

 not at all depressed, fairly narrow, a little convex transversely, as long 

 as the declivity. First node cuneiform, rounded, convex below as in 

 minutum, with a short peduncle in front shorter than the node, and 

 bearing below an obtuse tooth. Second node small, lower and not
