 cht'eks; in profile verj' convex in the n'inon of the frontal rarinae, with fwbly 

 convex fz:tilar surface. Kyes larp<' and convex, their anterior orhit>i at tlie 

 nie<lian transverse diameter of the head. I'alpi lon^ and slender. Manclihles 

 ni(xlenitely convex, witli four stout, suheipial t«H'th. ClyjM'UH semicircular, 

 convex, ecarinate; its anterior border very fivhly sinuate on each side of the 

 middle which does not project as a lobe. Clj'pcal fossa very pronounced. 

 Krontal an'u indistijict, trianjrular. Frontal carinae approximat<>d, sinuate, 

 erect, not further apart Ix^hind than in fn)nt. Antennae long, their scapes 

 extending fully half their length beyond the occipital border of the head. 

 Thorax subcylindrical, narrower than the head, a little broader through the 

 j^sterior part of the pronotmn than through tin- meso- and epinotum which 

 are of equal width; pro- and mesoepinotal sutures very distinct and strongly 

 inipresseil. Pronotuni, excluding the neck, a little broader than long, rounded 

 on the sides, with two stout, straight, acute spines which are twice as long as 

 the width of their bases and directed fonvard and outward. Mesunotum ;is 

 long as broad, its anterior outline semicircular, its lateral and posterior borders 

 straight, the sides not marginate. Epinotum compressed above, the base 

 horizontal and slightly concave, oblong, strongly marginate on the sides, the 

 marginations continued into the spines which are stout, straiglit, acute, twice 

 as long as those on the pronotuni and as long as the base of the epinotum, 

 laterally compressed, and directed backward and ver^- slightly upward. The 

 epinotal declivity is abrupt, sliglitiy concave in profile, not marginate on^the 

 sides, with large, prominent stigmata. Petiole subcuboidal with a denticle 

 on each side below near the anterior border and above with two ^tout, com- 

 pressed, curved spines, a little longer than those on the epinotum and directed 

 outward and backward. The distance between their tips is less than half the 

 diameter of the first gastric segment. Caster large, broadly elliptical, less 

 than half of it formed by the first segment, slightly flattened dorsoventrally, 

 convex but not truncated in front. Legs long; tibiae cylindrical, slightly 

 constricted at the base, without bristles on their flexor surfaces. 



Mandibles and clj-peus smooth and shining, the former minutely and sparsely 

 punctate; head shining above, subopaque on the sides; shagreened, the vertex 

 and sides of the front sparsely punctate. Thorax and petiole opaque; sides 

 of the former densely and evenly punctate, the dorsum verj' finely punctate- 

 rugulose, the rugules on the mesonotum obscurely concentric, the base of the 

 epinotum, especially behind, smooth and shining. Petiole indistinctly 

 punctate, sUghtly shining between the insertions of the spines. Gaster shin- 

 ing, ven.- finely and superficially shagreened or aciculate, with small, sparse 

 punctures; legs more opaque and more coarsely shagreened.
