ABT. 13. ANTS FROM HONDURAS AND GITATEMAI.A MANN. 35 



triangular spines at sides a little in front of middle. Mesoepinotal 

 suture deeply impressed. Base of epinotum about equal in length 

 to the declivity, its surface feebly convex above; spines slender, 

 slightly curved upward, longer than their distance apart at base. 

 Petiole with peduncle slender and much longer than the node ; node 

 in profile a little longer than broad, rounded above. Postpetiole 

 barely broader than the petiole and a little longer than broad. 



Shining throughout, petiole, postpetiole, gaster and appendages 

 more than the head and thorax. Head with large, shallow, foveolate 

 punctures and feebly reticulated between, thorax coarsely reticulated, 

 base of epinotum reticulated more finely than the thorax, with ir- 

 regular, transverse, rugae apically. Petiolnr peduncle densely punc- 

 tate and subopaque. 



Mandibles with several fine long hail's near tips. Head, thorax, 

 petiole, postpetiole and legs with short, semirecumbent stout hail's, 

 which are most abundant on the head. Gaster with sparse, micro- 

 scopic pubescence. 



Color reddish brown, petiole, postpetiole and gaster black, legs 

 lighter, with the tibiae infuscated, especially apically. 



Female.— {deal?ited) Length 4.10 mm. 



Very similar to the worker, with the usual sexual differences. 



Ti/pe locality. — Honduras : Progresso. 



Coty'pe8.—C2it. 24455, U.S.N.M. 



Described from several workers and one dealated female. The 

 colony was nesting in rotten wood. The movements in life are slow, 

 like most of the species of Strumigenys. 



A. lemtus differs from A. ocellatus Mayr, the only other known 

 species in its darker color, the more distinct sculpture of the head 

 and thorax and in having the occiput rather narrowly excised. In 

 ocellatus the latter is more broadly and roundly excavated. 



STRUMIGENYS (STRUMIGENYS) LUDIA, new species. 



Worker. — Length, including mandibles, 2.90 mm. (fig. 17). 



Head about one-fourth longer than broad, deeply and roundly 

 excavated behind, occipital corners narrowl}^ rounded; sides in front 

 of eyes biconvex, behind eyes feebly convex. Mandibles slightly les;^ 

 than three- fourths as long as head (from occipital corners to anterior 

 border) nearly straight, of subequal width except at base and tip, 

 with three slender apical teeth, the middle of which is one-third as 

 long as the basal and terminal. Clypeus triangular, a little broader 

 than long, shallowly concave at anterior border, the median surface. 

 in front of middle, elevated into a low, rounded tubercle. Supraor- 

 bital carinae straight, divergent, two-thirds as long as antennal 

 scapes; scrobes broad and moderately concave. Antennal scapes 

 very slender, extending four-fifths the distance to occipital corners ;
