" c?. Mandibles with 4 or 5 teeth. Head much longer than 

 broad. Scape as long as the first four joints of the flagellum. 

 Scutellum very prominent. The basal i'aco of the metanotuiu 

 has a deep transverse impression posterior to its middle, behind 

 that two strong obtuse teeth. Anteriorly it rises with a slope 

 towards the postscutellum. Nodes of the pedicel very low and 

 depressed, the first a little distinct from its pedicel. Pilosity 

 longer and more pointed than in the 2 . The rest resembles the

" ^ . More slender than the preceding. The head is not oval 

 but the anterior margin is broader. Behind the eyes it is 

 constricted, the sides slightly convex, curving gradually to the 

 articulation with the thorax. Dimensions of the antenna^ as in 

 A. rothneijl. Pronotum without tubercles. The mesonotum has 

 in its middle a raided transverse crest-like projection, somewhat 

 more pinched and flattened and a little more prominent than the 

 transverse ridge or carina on the mesonotum of A. smi/thk>si. 

 Behind this crest the mesonotum is sloping and bears a transverse 

 medial impression. Basal face of the metanotum convex as in 

 A.patruelis. Spines rather stout, wide apart, as long as two-thirds 

 of the distance between them. Eirst node a little broader than 

 in A. rothnei/i, with a slight petiole. Second Jiode as in A. .'^chitrri, 

 but a little shorter and broader. Smooth and shining all over. 

 Front of the liead and metanotum in part feebly reticulate. Some 

 few stricB around the eyes. Pilosity scattered, more setiform and 

 obtuse than in the two preceding species. That of the tibiae and the 

 scape as in A. schnrri. Brown; legs, mandibles and antenna^ 

 yellowish. This form may be merely a race of A. rotJuiei/i.'' [Forel.)
