broad as head, strongly convex in pi'ofile. sides and humeri rounded. 

 Mesoepinotal impression stroni:;. Base and declivity of epinotum 

 rounding into each other, both surfaces flat: spines erect, elongate- 

 triangular, rather bluntly pointed, shorter than their distance apart 

 at base. Petiolar node cuneiform, much shorter than the peduncle, 

 upper border concave at middle. Postpetiole broader than long 

 and nearly twice as broad as petiole; sides subangulate in front of 

 middle, (raster elongate. 



Shining. Mandibles sparsely punctuate. Head with rather fine, 

 elongate, separated longitudinal striae, that extend two-thirds the 

 distance from anterior border to occiput (in antennal fossae finer 

 and more approximate) ; posterior portion of head and the thorax 

 and abdomen with regular, rather sparse punctures. 



Fine, moderately long, erect, yellowish pilosity abundant on head, 

 body and appendages, sparser and semirecumbent on mandibles. 



Dark reddish brown, anterior portion of head and the clypeus red, 

 legs brownish yellow. 



Worker. — Length 1.5 mm. 



Head a little longer than broad and about as broad in front as 

 behind, sides and posterior border nearly straight, occipital angles 

 broadly rounded. Mandibles with eight unequal, separated trian- 

 gular teeth. Clypeus convex behind, flat in front, broadly rounded 

 at anterior border. Antennal scapes surpassing occipital borders by 

 one-seventh of their length ; funicular ioints 2-8, a little longer than 

 broad; basal joint of club distinctly longer than the second, terminal 

 joint about as long as the other two together. Thorax a little more 

 than half as broad as head, evenly convex in profile, with rounded 

 sides and humeri. Base and declivity of epinotum subequal, flat, 

 rounding into each other ; spines very small. Petiole and postpetiole 

 as in soldier, but the dorsal surface of the petiole is not excised. 



Shining: Antennal fossae with concentric separated striae. Man- 

 dibles, head and body sparseh% distinctly puncuate. 



Pilosity and color as in soldier. 



Type locality. — Honduras: San Juan Pueblo. 



Cotypes.— Cat. No. 24450, U.S.N.M. 



Described from eight soldiers and three workers. 



In the shape of its head. Ph. hondurensls approaches Ph. ahsurda 

 Forel. The latter species has the head proportionately longer, the 

 antennae are distinctly shorter and the eyes much smaller, the struc- 

 ture of the petiole and postpetiole and the sculpture is quite different. 

 Ph. hicor7iis Forel, which also has the frontal lobes projecting angu- 

 lately forward, has a shorter head than honduretisis , the clypeus is 

 distinctly concave in front and the head and thorax are subopaque 

 and reticulatelv rugose.
