other species which I have seen the fourth joint is more or 

 less deeply excavate interiorly, nearly throughout its length 

 and is, in addition, strongly heniin flavicorne. 



Although the present species bears a remarkably strong 

 resemblance to veterator in its sculpture, it may be distin- 

 guished by its sparser pubescence, slightly more elongate 

 prothorax, much deeper interocular striae, but especially 

 by the form of the ocelli, which in this species are fully 

 twice as wide as in veterator, and more indefinite in outline; 

 no dependence is placed on color as this is known to vary 

 greatly; it is, however, strikingly different in the represen- 

 tatives of the two species. 



A. floyibundam Lee. — One specimen which I have referred 

 to this species was collected by Mr. Fuchs in Lake Co. 

 The antennae are relatively longer and more filiform than in 

 any here described, and are piceous except the first three 

 joints and the bases of some of the succeeding ones. 



The relationship of the species here described with those 

 given by Mr. Fauvel (Not. Ent. vii, p. 72), is best shown 

 by the following table, which is merely a continuation of 

 the one given by that author, with a few slight alterations. 



Elytra shining, wifh more or less distinct punctuation. 

 Pronotum and elytra glabrous. 

 Pronotum polished. 



Elytra with very sparse, nearly obsolete punctuation sparsum. 



Elytra coarsely and generally distinctly punctate. 



Head distinctly and densely punctate; elytra black or maculate with 

 testaceous, with the suture blackish or brownish. 



Antennae piceous, three basal joints paler floribundlini. 



Antennae clear flavate throughout .. .flavicorne. 



Head impunctate. 

 Head shining, with two oblique striae between the eyes, .scutatum. 

 Head dull, granulose, strongly bifoveolate between the eyes. 



laevicolle. 



Head and pronotum alutaceous, size large testaceum. 



Pronotum and elytra visibly pubescent or pilose. 



Size large; pronotum and elylra very strongly and densely punctate, the 

 former distinctly impressed along the middle maculatum.
