tips of tarsi testaceous; abdomen convex, finely punctured, more coarsely so 

 towards apex, incurved, sides and apical margin of the segments with a fringe 

 of white pubescence; sixth segment with a short acute tooth on each side; 

 apex of seventh segment coarsely rugose, squarely produced at tip (fig. 2) and 

 slightly recurved, ventral segments 2—4 emarginate on apical middle, second 

 segment not at all produced on disk. Length .32 inch. 



ffai.— Georgia, (Morrison). One specimen. Very distinct from 

 proJucta in the shape of the seventh abdominal segment which is 

 broadly truncate at tip as in figure 2 of above cut, while that of 

 producta is pointed, as in figure 1. 



Anthidiuiu cognatum.— ?.— Black; head and thorax densely and 

 finely punctured, clothed with a whitish pubescence, very dense on face and 

 sides of thorax; oblong spot on each side of face, two spots on apical margin of 

 clypeus, large spot on each mandible, transverse spot on each side of occiput, 

 spot on tegulse anteriorly, a dot above, spot on each side of scutellum, inter- 

 rupted line on posterior margin, spot or line at base of tibiae, and a subapical 

 band on abdominal segments 1—5, (broadly interrupted on each side and on 

 middle, so as to form four spots on each segment, those on extreme sides larger, 

 the two middle spots small and narrow on first, gradually becoming larger 

 to fifth segment which is destitute of the lateral spots), yellowish ; legs with 

 whitish pubescence, very dense on basal joint of tarsi; wings smoky towards 

 tip, neuration as in maculifrons ; abdomen broad, shining, finely punctured, 

 sixth segment densely punctured, apical margin subsinuate on each side 

 with prominent lateral angles; ventral scopa dense and whitish. Length 



,40 inch. 



% .—Much larger, with pubescence on vertex and thorax above yellow and 

 more dense; sides of face, clypeus, mandibles excei^t tips, line behind ocelli 

 broadly interrupted on middle, scape in front, spot on tegulse in front, dot 

 above, narrow interrupted line on posterior margin of scutellum, four anterior 



. tibiaj in front, spot at base of posterior tibiae, basal joint of tarsi, 



\\~I?y yellow; abdomen marked much the same as in 9 , except that 

 UwU the lateral spots on segments 3—5 are connected with middle 

 spots by a slender line; sixth segment has two median emarginate spots, and 

 a prominent acute incurved tooth on each side, while the apical segment 

 (see figure) has three long prominent teeth, the lateral ones rather broad 

 and obtuse and the middle one a little shorter, acute and slightly incurved. 

 Length .50 inch. 



J£^llJ^ — Georgia, (Morrison). Two specimens. Allied to maculifrons 

 Smith, but the shape of the apical segment ot abdomen is very differ- 

 ent, that of maculifrons and of mormonus, described below, being 

 almost exactly alike. 



Anthidium axtecum.— 9 .—Black ; head and thorax finely and densely 

 punctured, clothed with pale pubescence, very dense on face and sides of 

 thorax; spot on lower side of face, two spots on clypeus, spot on mandibles, 

 spot behind summit of each eye, spot on tegulse in front, posterior margin of 

 scutellum interrupted laterally, line or spot at base of tibise, a spot on each 

 side and two dots on middle of first abdominal segment, a band on second 

 segment interrupted into four spots, a band on segments 3—5, those on three
