margiu and denticulate above; clypeus proportionately much 

 smaller, its anterior margin rounded ; antennal hollows not so 

 large, antennal carinse prominent, convergent posteriorly ; antenna; 

 very long and filiform, the scape passing beyond the top of the head 

 by about one-fourth of its length, flagellum with the proportions of 

 the joints as in A. beccarii. Thorax elongate, narrow, the pronotum 

 not constricted into a neck anteriorly, posteriorly slightly raised 

 into lateral tubercles ; the pro-mesonotal suture well-marked ; the 

 mesonotum slightly raised, iu some specimens with two transverse 

 impressions ; metanotum elongate, rounded above ; metanotal spines 

 thick at base, acute at apex, and as long as the distance between 

 them at base; legs long and slender. Pedicel: 1st joint with the 

 node conical, rounded above, petiolate in front and posteriorly, the 

 anterior portion more slender and twice as long as the posterior 

 portion ; 2nd joint with a pyriform node strongly constricted 

 anteriorly ; abdomen very broadly oval, subglobose.

$ . Head and posterior half of the thorax black, the pronotum 

 and anterior half of the mesonotum black with a deep red tinge, 

 mandibles, antennae, legs, pedicel and abdomen yellowish brown ; 

 head and thorax very coarsely longitudinally rugose striate, the 

 striae broken and irregular (the sculpture resembles that of 

 3/?/nm'ra marf/aritce) ; legs, pedicel and abdomen highly polished, 

 smooth and shining ; pilosity white, rather long and most abundant 

 on the abdomen above, the hairs as usual obtuse at apex. Head 

 oval but with a distinct posterior margin, not elongated into a neck 

 posteriorly; mandibles finely and closely longitudinally striate, the 

 masticatory margin dentate, the apical three teeth the largest ; 

 clypeus transversely slightly convex, its anterior margin rounded ; 

 antennal hollows rugose, large, not margined laterally by a carina 

 as apart from the rugosity between the eyes and the antennal 

 hollows ; antennal carinae as in A. rothneyi, but much more pro- 

 minent ; antennoa long, filiform, the scape extending beyond the 

 top of the head by about one-fourth of its length ; joints 2-7 

 of the flagellum distinctly shorter than in A. rothneyi, the club 

 formed of the apical four joints ; eyes lateral, round and prominent, 

 equidistant from the anterior and posterior margins of the head. 

 Thorax very nearly as broad as the head, the pronotum depressed 

 a little in the middle ; pro-mesonotal suture very distinct, the 

 mesonotum raised so as to form, when viewed from the front, a 

 transverse ridge; meso-metanotal suture deeply impressed, the 

 thorax above emarginate at the suture ; basal portion of metanotum 

 convex, elongate, the rugosities particularly deep and coarse above ; 

 the metanotal spines close together, very erect and robust, distinctly 

 longer than the interval between their bases ; apical face of the
