?. Opaque black, deeply and closely punctured; a line behind

 insertion of the antennas, and the basal half of the clypeus, deeply 

 and squarely emarginate before, obscure yellowish ; antenme 

 black, the basal joint, except the apical half above, yellow. 

 Thorax; the anterior margin of the prothorax slightly interrupted 

 on the disk, a small quadrate spot on the disk of the mesothorax 

 posteriorly, tegulae, a minute spot on each side just behind the 

 tegulae, a round spot on each side of the pleura, the post-scutellum, 

 and an elongate mark on each side of the metathorax, yellowish. 

 Legs black; tips of the four anterior femora, their tibiae, and the 

 posterior tibiae, except tips, yellowish. Abdomen robust, not 

 much contracted at base ; basal segment roughly punctured, with 

 a faint transverse suture at base, its apical margin bordered in 

 the middle, continued along the lateral margin, and then produced 

 to within about one-fourth the width of the segment, yellowish; 

 second segment large, convex, shining, finely punctured, more 

 strongly at the tip; the apical margin above and beueath, and a 

 rounded spot on each side near the base, as well as the apical 

 margin of" the fifth segment, not quite reaching the sides, yellow.

 posterior tibiae, except their tips, yellowish. Wings fuscodiyaline, 

 darker along the costa, darkest in the radial cell. 



Bets. a. diff. — Closely allied to A. bacuensis, but it is distin- 

 guished by its more robust form, the spot on the disk of the 

 mesothorax, the absence of bands on the fourth and sixth seg- 

 ments of the abdomen, its black scutel, etc. 



It is still more closely allied to A. saecularis, if not the same.
