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

 the eyes near their summit, the sinus in front, a spot between the 

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

 and squarely emarginate before, obscure yellowish ; antennas 

 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, tegulaa, a minute spot on each side just behind the 

 tegulee, 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 beneath, 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. 

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

 posterior tibiae, except their tips, yellowish. Wings fusco-hyaline, 

 darker along the costa, darkest in the radial cell. 



Bess. 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. ssecularis, if not the same.
