Last abdominal segment smooth, polished. 



Male front and middle tarsi with the joints thickened, the first and 

 second being feebly produced. 



Male and female types, from Staten Island, N. Y., are in my col- 

 lection. 



Named for my friend and associate of many years, Mr. Charles 

 W. Leng, who was acting as my guide to the haunts of Bidessiis 

 flaz'icollis when the fourteen specimens before me were taken. In 

 addition to the above I have seen a single specimen, taken at Cham- 

 bersburg, Pa., by Mr. J. D. Sherman, Jr. The species is distinct from 

 12-piinctatus by its coarser elytral punctuation, the lack of any sub- 

 humeral spot, or dash of black, the scarcely subangulate apices of the 

 coxal plates, which are distinctly angulate, or produced, in i2-pnncta- 

 tus, and the much broader yellow band on the hind femora. From 

 cdentnlus it is at once separated by the lack of a black collar on 

 vertex of head and the structure of the under side of the body, as well 

 as coloration. 



These two are the only other species known with yellow-banded 

 hind femora. 



Peltodytes pedunculatus Blatchley. 



I have never seen authentic specimens of this species and the 

 author gives little else than maculation, as compared with mnticns, 

 to define it. 



Specimens of a species from Covington, La. (Mr. Coverdale), 

 separated by me as pedunculatus, have the sutural margin broad be- 

 fore the median spot, occupying the whole of the sutural interval, 

 and narrow below it. While the median spot may not perhaps be 

 called coalescent with the sutural border it touches the margin, and 

 there is a subhumeral spot. 



The apices of the elytra are feebly sinuate and slightly oblique. 

 The apices of hind coxal plates are subangulate and the last ab- 

 dominal segment smooth and shining. The posterior femora is very 

 dark brown. The prosternal process is feebly sulcate, not greatly 

 constricted. 



The species is distinct from sJicnnani, which is the pedunculatus 

 of my manuscript referred to by Mr. Blatchley, and also from 

 miiticiis and sexmaculatus. 



From Mr. Blatchley's definition of his species in his table I am
