inclined to think he had two species before him in making his synop- 

 sis of characteristics, perhaps sexmaculatus and his own. A single 

 specimen each from " Kansas " and Detroit, Mich., in the U. S. Natl. 

 Mus. collections, agree with the above-described specimens from Cov- 

 ington, La. 



Peltodytes littbralis Matheson. 



A very distinct species and easily separated from any other of 

 our species by the uniformly pale posterior femora, its light yellow 

 color and small but distinct spots on the elytra. The basal spots on 

 the pronotum are very small and do not touch the base in any of the 

 specimens I have seen. 



A dozen specimens are before me from Kansas and Texas. 



Peltodytes festivus Wehnke. 



This pretty little species is represented in the U. S. Natl. Museum 

 Collections. A careful examination shows the fourth stria to be very 

 broadly interrupted and the lateral one placed almost upon the mar- 

 gin. They are no more broadly interrupted, or closer to the margin, 

 than in some of our other species and, counting them, the species has 

 eleven striae instead of nine, as described by Mr. Wehnke. 



Peltodytes duodecempunctatus Say. 



In this species, as recognized by Aube, Leconte and Crotch, the 

 fourth elytral stria is very greatly interrupted. The strial punctures 

 of the elytra are coarse, except those of the iirst and second, and 

 very much diminished from about the median line to the apices. The 

 apices are sulcate, though not strongly so. The maculation consists 

 of six spots, placed as usual, and there is a black subhumeral dash 

 almost upon the lateral margin. This dash of black is usually quite 

 distinct, but I have seen specimens where it is represented by two or 

 three very deeply blackened punctures only. The suture is narrowly 

 margined with black and the median spot free. I have seen a few 

 specimens in which the black sutural border broadens out somewhat 

 towards the base, with the median spot barely touching it. The 

 margins of the prosternal process are rather thick, both lateral and 

 apical, and the constriction strong. The mid-metasternum has the 

 margins thick and short, not reaching more than half way to the 

 antecoxal piece, arched between the middle coxae and somewhat con-
