One specimen, from Republican Fork of Kansas river, kindly given me by Dr. 

 T. B. Wilson. The antenna) are slender and reach two-thirds the length of the 

 elytra ; behind the middle of the elytra and extending nearly to the apex is a very 

 obsolete yellowish stripe, which in other specimens may be found to be well de 

 veloped, in which case there would be on each elytron a subsutural vitta abbrevi 

 ated behind, and an external one abbreviated in front. 



Resembles in appearance some of the varieties of A. marginalia Lee. (? Leptura 

 loiujicornis Kirby), but the thorax is more robust and more rounded on the sides, 

 the legs are entirely black, and the apex of the elytra more rounded.

li. cribl ipeillliM, atra breviter parce pilosa, capite dense, thorace grosse punctate, hoc convexo, 

 lateribus late rotundatis, utrinquc constricto, elytris rubris subglabris, cribratim punctatis, ad

 antennarum 4, 5, G, 9 et lOnio basi pallidis, Cto et 8vo pallidis macula apicali parva nigra notatis. 

 Long. -7. 



One specimen found by me on Platte river. Very nearly allied to L. cinnam- 

 optera Kirby, but the elytra are much more coarsely punctured, and the lower half 

 of the fourth joint of the antenna} is pale, while in the latter species there is merely 

 a small pale spot at base.

New Mexico : one specimen : Dr. Wislizenus. Differs from the other species 

 known to me by the flattened back and suddenly deflexed sides of the elytra. 



STEHTOSTOL.A MULS. 



S. satlirninn, plumbco-nigra, undique cincreo-pubcsccns, thorace latitudinc haud longiore, punc 

 tate, lateribus subrotundato, pilis subtilibus erectis brcvibus parce vestito, versus basin densius 

 pubescente, elytris punctis remotis postice subtilioribns, ad apicem singulatim rotundatis. Long. 5. 



One specimen from Kansas, kindly communicated to me by Mr. Burke. From 

 its color it resembles at first sight Superda moesta and concolor, but the short con 

 vex front and dentate ungues will at once remind the student of the generic differ 

 ences. Of the usual smooth thoracic spots seen in the species of this genus, only 

 two very faint ones remain ; they arc situated about the middle, equidistant from 

 each other and from the side.
