IfjS CxTAK II. n(»n\. M. 1). 



The front claw of the anterior tarsus is cleft at some distance behind the tip, and 

 so feebly that it might escape observation. The claw joint of the tarsus is toothed 

 at middle beneath. The middle front claw is cleft at tip, the two portions nearly 

 equal. 



I'o this species, also, I refer two specimens from Arizona, which differ 

 in having the front more densely punctured, the thoracic spots larger, 

 and the suture and lateral margins of the elytra narrowly brown. By its 

 ])eculiar anterior claws this species is very readily known. 



Occurs in the Gulf States and Arizona. 



A. flavipennis Burm. — Moderately robust, rufescent; elytra testaceous, 

 rarely with darker spaces. Head moderately densely punctured. Clypeus broader 

 at base, margin rather widely reflexed. Thorax transverse, narrower in front; 

 sides regularly arcuate, base distinctly margined; surface sparsely punctured; 

 sometimes with a vaguely impressed median line. Elytra punctured, very few of 

 the strife are regular, three intervals more distinctly sub-costiform. Pygidium 

 rather coarsely punctured. Body beneath nearly smooth, with very few punctures, 

 pectus and costal plates hairy. Length .40 — .44 inch ; 10—11 mm. 



The anterior claw of the front tarsus is but little shorter than the posterior, the 

 tip is cleft, the two portions not very unequal, the base flexed. The (ilaw joint is 

 rather strongly toothed beneath. The anterior middle claw is cleft at tip, the 

 upper portion much more slender, but equal in length to the inferior. 



The pale testaceous elytra enable the greater number of specimens to 

 be recognized at once. Specimens occur in North Carolina with the 

 elytral punctuation somewhat coarser and deeper, and the costiform inter- 

 vals have in the basal region linear piceous spots. In the darker speci- 

 mens the thorax has a slight aeneous tinge. 

 Occurs in the Southern States. 



A. binota.ta Gyll. — Form moderately robust, piceous; thorax dark bronze, 

 shining: elytra yellowish testaceous, the suture and margin narrowly bordered, 

 and usually on each side two piceous spots. Head rather densely punctured. 

 Clypeus scarcely broader at base, the margin narrowly reflexed. Thorax narrowed 

 in front; sides arcuate, disc convex, sparingly punctured, toward the sides more 

 densely and with a larger foveate puncture. Scutellum bronzed. Elytra, with 

 strise, of coarse punctures, somewhat confused in the sutural region, three of the 

 intervals verj' slightly more elevated. Pygidium rather densely rugulose, and 

 with short hairs. Body beneath coarsely, not densely punctured, pectus, coxal 

 plates and sides of abdomen hairy. Length .40 — .44 inch; 10 — 11 ram. 



The claw joint of the anterior tarsi is distinctly toothed beneath. The anterior 

 claw is flexed at base, the tip cleft, the upper portion quite slender, and a little 

 sliorter than the lower. The anterior claw of the middle tarsus is cleft at tip, the 

 two portions nearly equal. 



The specimens from the eastern and northern parts of our territory have 

 the elytra more decidedly sculptured, and the two elytral spots well 

 marked. Specimens occasionally found have the sutural region near the 

 apex broadly piceous, the color extending often widely around the apical
