feebly impressed punctures, the inner of the usual sub-costiform intervals alone 

 distinctly elevated ; pygidium nearly smooth or sparsely punctate; body beneath 

 sparsely punctate, pectus hairy. Length .26 — .28 inch ; 6.5 — 7 mm; 

 The claws of all the tarsi are simple and slender. 



The color is variable. In the typical forms from Florida the general 

 color is testaceous, the head and an irregular thoracic space piceous. A 

 specimen in my cabinet is entirely piceous witli the sides of the thorax 

 alone testaceous. Another with head and thorax rufescent has the sides 

 of the elytra brownish. Others have the suture narrowly, and the sides 

 of the elytra more widely brownish. From this it is evident that the 

 markings have a tendency to a longitudinal and not a fasciate arrange- 

 ment. 



Occurs in Georgia and Florida. 



.4. cavifroilS Lee. — Oblong, oval, uniformly yellowish testaceous; front 

 densely punctured ; clypeus very little wider than long, the angles rounded, mar- 

 gin rather widely reflexed ; surface less punctured than the front, the frontal suture 

 distinctly carinate; thorax narrowed in front; sides arcuate, widest at middle, 

 sparsely punctate, a vague median line near the front, basal marginal line distinct; 

 elytra feebly striate, the striae very obsoletely punctured, the intervals slightly 

 convex; pygidium nearly smooth; body beneath very sparsely punctate, pectus 

 slightly hairy. Length .40 inch: 10 mm. 



Tarsal claws are simple. 



I have seen about ten specimens of this species of uniform color. It 

 is remarkable by the feeble punctuation of the elytra and the carinifurni 

 frontal suture. 



Occurs in Texas and New Mexico. 



Sub-genus Spilota. 



From the material of our fauna this division seems fully entitled to 

 generic value, but in deference to the views of Burmeister and Lacordaire 

 is retained in its present situation. The basal marginal line of the thorax 

 which exists in the preceding sub-divisions is entirely wanting here. 



Pygidium sparsely punctured, rather shining, with very little or no pubescence. 

 Thorax with sparse punctuation, between which the surface is shining. 



luc*ic<>la. 



Thorax rather densely and coarsely punctured, sub-opaque oblivia. 



Pygidium rather densely punctured, not shining, densely pubescent. 



niarginata. 



A. lucicola Fab. — Forin oval, robust: color variable from entirely yellow to 

 entirely black ; head moderately densely punctured ; clypeus transverse ; sides 

 very little divergent, angles rounded, margin in front narrowly reflexed ; thorax 

 convex ; sides regularly arcuate, gradually narrowed to the point, basal marginal 

 line obliterated, surface rather coarsely but not densely punctured; elytia with
