ART. 13. ANTS FROM HONDURAS AND GUATEMALA MANN. 21 



posterior half. Clypeus nearly flat between frontal lobes, short and 

 very moderately convex in front, indistinctly bicarinate at middle, 

 anterior border broadly rounded. Frontal lobes small, but promi- 

 nently elevated ; frontal carinae acute, slightly divergent, extending 

 beyond opposite posterior borders of ej^es. Antennal scapes barely 

 surpassing occipital corners ; first funicular joint nearly as long as the 

 following three joints together; joints 2-8 strongly transverse; last 

 four joints longer than broad and forming a rather slender club, ter- 

 minal joint shorter than joints 9-10 together. Eyes situated at sides 

 of head, well in front of middle, convex, much shorter than their dis- 

 tance from anterior border of head. Thorax robust, though narrower 

 than head. Pronotum in profile convex, inferior corners subangulate ; 

 from above, a little longer than broad with moderately convex sides 

 and rounded humeri. Mesoepinotal impression strong. Epinotal 

 base straight in profile, about as long as the declivity, with a pair of 

 triangular spines which are longer than their distance apart at base, 

 divergent and directed upward and backward. Petiole elongate, the 

 peduncle much longer than the node, which in profile is higher than 

 long and rounded above, and from above strongly transverse and nar- 

 rowly rounded at sides. Postpetiole rounded, as broad as, but dis- 

 tinctly lower than, the petiole. Gaster very broadly oval. Legs rather 

 stout. 



Shining. Mandibles coarsely and shallowly punctate and striate. 

 Cheeks coarsely and irregularly striate; remainder of head and the 

 gaster smooth. Thorax and epinotal base strongly, reticulately cost- 

 ate. Petiolar peduncle superficially punctate, node smooth. Post- 

 petiole smooth above, at sides with sparse and coarse punctures. 

 Legs shining. 



Fine very long and erect yellow hairs abundant on head and body, 

 shorter on appendages. 



Jet black; appendages brownish red, with the femora and tibiae 

 strongly infuscated except at bases and tips. 

 Type locality. — Honduras: Lombardia. 

 Cotypes.—Q'dX. No. 24447, U.S.N.M. 

 Described from two workers collected beneath a stone. 

 This species strikingly resembles some of the species of Piistoniyr- 

 7nex in its sculpture, it is like a small Roger'm in habitus and in 

 having the inferior prothoracic corners angulate, but because of the 

 4-jointed antennal club and the structures of the head I have placed 

 it in Stenanima., with doubt. 



STENAMMA FELIXI, new species. 



Worker. — Length 3.75 mm. (fig. 10). 



Head a little longer than broad and as broad in front as behind, 

 sides feebly convex, occipital corners rounded, border straight. Man-
