to form part of the long neck ; pro-mesonotal suture tolerably dis- 

 tinct ; the mesonotuin behind the suture forms a raised transverse 

 ridge, posterior to which it curves downwards to the very distinct 

 meso-rnetanotal suture ; the basal portion of the metanotum long, 

 horizontal, and with two slender, very acute erect spines at the 

 posterior lateral angles, apical portion steeply sloped, a little 

 convex; legs remarkably long and very slender. Pedicel seen 

 from above with the 1st node only half the width of the 2nd, the 

 latter broadly oval, rounded above, both shortly petiolate in front; 

 abdomen a broad regular oval. 



Length, 4'5 mm.

. Piceous brown, smooth, polished and shining : mandibles, 

 antennae and legs yellowish brown ; thorax posteriorly with a 

 little irregular sculpture ; pilosity rather sparse, the hairs long, 

 thick and obtuse. Head with the mandibles oval, prolonged 

 posteriorly into a neck with the posterior border margined ; man- 

 dibles finely striate at base, the masticatory margin with two teeth 

 at apex, and above denticulate ; clypeus slightly convex ; ant ennui 

 carinae short, very prominent, convergent posteriorly ; antennal 

 hollows large, smooth inside, margined laterally by prominent 

 carinae ; antennae long and filiform, the scape extending beyond 

 the top of the head by about one-third of its length, the basal 

 joint of the flagellum slightly longer than the 2nd joint, the club 

 formed of the apical 4 joints, which are only slightly thickened 

 and densely pubescent ; eyes lateral, subacuminate anteriorly. 

 Thorax narrow, elongate ; the pro- and mesonotum forming one 

 long convexity, the pro-mesonotal suture obsolete above ; the 

 thorax seen in profile emarginate at the meso-metanotal suture ; 

 ba.^al portion of metanotum elongate, slightly flattened above, 

 posteriorly with two erect, acute, short spines or teeth ; legs very 

 slender and long, the pilosity on them oblique. Pedicel slender, 

 the 1st node oval, longer than broad, the 2nd node oval, much 

 higher and slightly broader than the 1st ; abdomen broadly oval.

$ . Brown, the head darker than the rest of the body, man- 

 dibles, antennae and legs brownish yellow ; head and thorax finely 

 reticulate, striate, subopaque, the metanotum more coarsely and 

 transversely sculptured ; abdomen polished, smooth and shining. 

 Head with the mandibles oval, not constricted into a neck posteriorly, 

 as in A. beccarii ; mandibles longer than in that species, finely striate 

 at base, with three largish acute teeth at the apex of the masticatory
