ART. 13. ANTS FROM HONDURAS AND GUATEMALA MANN. 15 



fourth their length; funicular joints one-third longer than broad, the 

 rest except the terminal as broad or slightly broader than long. Pro- 

 notum longer than broad, little convex above. Mesonotum trans- 

 verse. Epinotum as long as pro and mesonotum together, base in 

 profile slightly convex, declivity flat, obtusely margined at sides on 

 upper half, the margins terminating as stout, blunt spines. Petiolar 

 node in profile higher than long, as broad above as below, with abrupt 

 anterior and posterior faces and broadly convex dorsum ; from above, 

 distinctly broader than long and only slightly narrower in front 

 than behind. Gaster and legs rather stout. 



Strongly shining. Finely punctate throughout and with mod- 

 erately abundant fine erect hairs. 



Color ferruginous. 



Type locality. — Honduras: Ceiba. 



Cotyfes.—Q^t. No. 24442, U.S.N.M. 



Described from one worker. 



The small size, robust form, stout antennae and dentate sides of 

 the epinotal declivity are similar to those characters in L. fusUhis 

 Emery, which differ from rufa in having the head elongate, the 

 petiole longer than broad and in color. 



LEPTOGENYS (LOBOPELTA) CONSANGUINEA Wheeler. 



Honduras : San Juan Pueblo. 



A single worker taken beneath leaves on the ground agrees closely 

 with cotypes in the Wheeler collection. 



LEPTOGENYS (LOBOPELTA) IMPERATRIX, new species. 



Worker. — Length, 10 mm. (fig. 8). 



Head elongate, constricted behind to about half its width at 

 clypeus, sides little convex. Eyes large and convex, nearly as long 

 as their distance from the anterior border of head. Mandibles rather 

 broad, the basal and apical borders separated by a rounded angle; 

 apical border evenly concave. Clypeus carinate at middle, the an- 

 terior median portion filling the space between the closed mandibles, 

 sides nearly straight, anterior border subtruncate. Antennae very 

 long ; scapes surpassing occipital corners by about half their length ; 

 second funicular joint much longer than the third, third joint nearly 

 five times as long as broad, remaining joints gradually decreasing 

 in length, the penultimate two and a half times as long as broad 

 and the terminal shorter than the two preceding joints together. 

 Thorax at broadest point a little narrower than the head, pronotum 

 longer than broad, mesonotum less than a third as long as pronotum. 

 Epinotum distinctly longer than pro and mesonotum together, in 

 profile the nearly straight base broadly rounds into the short de- 

 clivity. Petiolar node strongly compressed, in profile longer than
