*JBT. 13. ANTS FROM HONDURAS AND GUATEMALA MANN. l7 



Diltering from the worker in having the petiolar node much shorter, 

 in profile a little higher than long and more convex above, and in the 

 enlarged gaster. 



2'ype locality. — Honduras: Lombardia, San Juan Pueblo. 



Cotypes.—Cfit. No. 2dt443, U.S.N.M. 



Described from a series of workers and one female taken in rotten 

 wood and beneath logs. 



In its elongate slender form, constricted head and the large size of 

 the eyes i7iiperatrlx resembles famelica Emery from Costa Rica. The 

 latter species, however, has the petiole shorter and much less con- 

 stricted in front (seen from above), the anterior portion of the 

 clypeus is broader and the mandibles differently shaped, the sculpture 

 is different and the gaster, judging from Emery's description, lacks 

 the rather dense, almost pruinose covering that occurs in imyeratrvx. 



ANOCHETUS (ANOCHETUS) MINANS, new species. 



W orher. — Length, including mandibles, 3.5 mm. 



Head broad, deeply incised behind, posterior corners narrowly 

 rounded, sides concave posterior to eyes, bluntly angulate outward 

 from eyes and bisinuate in front. Mandibles much shorter than head, 

 anterior two-thirds thickened, inner surface of blades swollen at 

 middle, edentate, terminal teeth stout, rather blunt at tips, the basal 

 thicker and shorter than the last, the second half as long as the apical. 

 Frontal carinae extending to opposite posterior borders of eyes, more 

 elevated than in nnayri Emery. Eyes small, with 6-7 large facets. 

 Antennal cavities large, bordered outwardly by a thickened carina 

 stronger than in mayri and roundly angulate at anterior third. An- 

 tennal scapes not attaining occipital corners; first funicular joints as 

 long as the second and third together, joints 2-7 elongate, but a little 

 less than twice as long as broad, joints 8-10 twice as long as broad, 

 terminal joint slender, acute, slightly shorter than the three preced- 

 ing joints together. Pronotum, excluding frontal narrowed portion, 

 as long as broad, widest at posterior half. Meso and epinotum as in 

 mayri but the epinotal spines are coarser and more rounded at tips. 

 Petiolar node in profile a little thicker than in mayri and above more 

 shallowy concave, with the lateral points shorter and less acute. 



Moderately shining. Mandibles finely punctate and sparsely pilose. 

 Head in front densely striated longitudinally, at sides obliquely 

 striate, punctate behind. Pronotum at sides with longitudinal striae 

 and punctures, disk finely punctate. Epinotum rugulose-punctate. 

 Petiolar node superficially striate at base. Gaster finely and regu- 

 larly punctate. 



Head, body, and appendages with rather sparse, recumbent pile. 

 Erect, coarser hairs scattered on head and thorax, more abundant on 

 gaster.
