stnii({ht, siil>]):ir:illcl sides. Iiildlu'd Ix-liiiid, (i\\in^ to tli<> deep, angular occipital 

 inrisinn, which is contimuHl into a dcc-p occi]>ital and frontal uriMtvc all tin- 

 way to the fnintal luva. Eyes small, niodcratoly convex, elonKat<* elliptical 

 at the anterior third of the head. Mandibles verj' lar^e and convex, with 

 very broad, straight, edentate ai)ical and very concave basal borders. ClyiH-us 

 depressed on the sides and l>eliind, convex and roof-like, but not <'arinate in 

 the middle in front, where it projects tiver the proximal ends of the apical 

 mandibular borders as a short lobe, with straight margin and itidistinctly 

 dentate corners. I'rontal area rather distinct, triangular. Frontal carinae 

 strongly diverj^ing behind, each bortlering a deep narrow scrol>e for the ant«'nnal 

 seajic, running down oblicjuely to the side of the head a little behind and above 

 the eye. At this \nnn\ it turns sharply at an angle to form a short scrobe for 

 the base of the funiculus, running fonvard ja>^t above the eye and merging 

 anteriorly into an int<Trugal space. Anteimae slender, the scajn^s curved and 

 flatteneil but not dilated at the ba.se. Funiculi with a 3-jointe<l dul), shorter 

 than the remainder of the funiculus; joints 2-8 as long as broad. Thorax 

 short, less than half as broad tis the head; pro- and mesonotum rather de- 

 pressed dorsally where they are covered by the posterior portion of the head; 

 pronotum without spines. Mesoepinotal constriction not very pronounced. 

 Epinotum verj- short, its base much shorter than the vertical declivity; the 

 spines ver>' long, slightly curved downward, thick at the base, strongly tajK'ring 

 at the tips;, diverging outward, backward and upward, much longer than their 

 distance ai)art at the base. Metasternal angles small, acute, directed ui)ward. 

 Petiole from above nearly twice as long as broad, a little broader In-hind than 

 in front, with concave sides and narrow node, armed with two upwardly 

 directed acute spines, the space between which is semicircular; anterior 

 surface of the node long and concave, the posterior straight and abrupt. 

 Postpetiole a little broader than the petiole and a little broader than long, 

 verj" convex dorsally and rounded on the sides. Gast^r only about J as large 

 as the head, subcireular. flattened, with straight anterior border. Femora 

 thickened in the middle, tibiae somewhat davate. 



Rather shining; mandibles smooth, with very fine, widely scattered punc- 

 tures. Cl.N-peus smooth and shining. Head covered with umbilicate i)iliger- 

 ous foveolae, elongate on the gular surface, on the space between the frontal 

 carinae interspersed with strong, diverging longitudinal rugae; cheeks coarsely, 

 longitudinally rugose, space enclosed by the two limbs of the scrobes coarsely 

 reticulate-rugose; the scrobes smooth and shining, not transversely rugose. 

 Thorax coarsely and reticulately rugose; epinotal declivity between the spines 

 and the whole petiole smooth and shining; postpetiole coarsely and indis- 

 tinctly rugose above, subopaque. Gaster smooth and shining. 



Hairs pale grayish, short, erect, blunt, but not thick, sparse, covering the 

 scapes and legs including the funiculi and tarsi as well as the body, more 

 abundant on the gaster; on the antennal scapes, most numerous on the anterior 

 surface; on the legs, most numerous on the extensor surfaces. 



Deep ferruginous brown; mandibles, antennae, legs, epinotal spines, and 

 peduncle of petiole deep red; gaster and borders of mandibles blackish.
