AST. 13. ANTS FROM HONDURAS AND GUATEMAT^ MANX. 41 



epinotal declivity. Peduncle of petiole n little longer than the 

 node; node in profile slightly higher than long, abrupt in front 

 and behind and nearly iiat above; from above, as long as broad, 

 feebly convex at sides and straight at front and , posterior borders. 

 Postpetiole much broader than petiole and more than twice as broad 

 as long, longitudinally concave at middle. 



Opaque. Head and thorax punctate and rugulose, epinotum trans- 

 versely seriolate; petiole, postpetiole and gaster cribately punctate. 

 Mandibles, legs, and antennal scapes densely punctate. 



Subappressed squamiform hairs moderately abundant on head, 

 body, and appendages, sparse on epinotum; longer, clavate hairs 

 on outer border of antennal scapes and the apical portions of legs; 

 coarser, clavate hairs regularly arranged on head, thorax, and ab- 

 domen. 



Brownish red; legs paler. 



Female. — Length, 2.90 mm. 



Thorax and scutellum rugulose, the former more strongly than 

 in the worker. Epinotal spines a little shorter than in workers. 

 Wings strongly infuscated. 



Male. — Length. 2.80 mm. 



Head, excluding mandibles, longer than broad, shallowly and 

 broadly excised behind, posterior portion of sides truncate. Cly- 

 peus broad, rounded at sides posterior to middle, ver}- feebly concave 

 at anterior border. Mandibles well developed, acute at tips, their 

 blades strongly concave. Eyes elongate oval, convex, slightly shorter 

 than their distance to occipital corners. Ocelli large. Frontal lobes 

 prominent, truncate apically. Antennae 13-jointed. first joint twice 

 as broad at base as at apex, twice as broad and slightly longer than 

 the second joint, which is about half as long as the third, joints 3-12 

 elongate, subcylindrical, terminal joint longer than the penulti- 

 mate, but shorter than the two preceding joints together. Mesotho- 

 rax shallowly, longitudinally impressed at middle, shallowly con- 

 cave behind. Scutellum about as long as broad, little convex, im- 

 pressed at middle of posterior border. Base and declivity of epi- 

 notum equal in length; spines bluntly triangular, a little longer 

 than broad at base, declivity narrowly margined at sides. Petiole 

 elongate, the node rounded above ; from above, a little broader than 

 long, rounded at sides and straight in front; anteroventral spine 

 long and pointed, directed forward. Postpetiole transverse and twice 

 as broad as petiole. Gaster rather strongly narrowed behind. Ex- 

 ternal valves of genitalia long and slender, narrowly rounded api- 

 cally. Legs long and very slender. 



Gaster shining, pleurae, in part, and petiolar node feebly shining, 

 the rest opaque. Head and thorax densely punctate and rugulose.
