Lately this difficulty has been dispersed by a comparison of the 

 localities for the specimens which lack the lateral sinuation of the 

 elytra, viz. : Ohio, Indiana, Kentucky, Tennessee, all west of the 

 Allegheny Mts., with the type locality for hcros given by Dr. Harris, 

 " Ohio and Indiana," for it became plain that the specimens from the 

 west, that are without the lateral sinuation, were the true licros and 

 differed specifically from those from Washington, D. C, in which the 

 lateral sinuation of the elytra is always well developed. Showing the 

 material to Mr. Wm, T. Davis, he at once detected a further ditTer- 

 ence in the form of the thorax so I propose to add one more name 

 to our list, dedicating it to the collector who has taken and distributed 

 the largest number, by calling it Sccipliiiiotiis shocmakcri new sub- 

 species. 



This sub-species resembles 6". hcros but differs especially in the 



greater a])i)roximation of the hind angles of the thorax which are 

 separated in hcros by 7 mm. making the sides of the thorax nearly 

 parallel, while in shocmakcri the much higher and more reflexed hind 

 angles approach each other within 5 mm., making the sides of the 

 thorax somewhat convergent; as well as in the lateral sinuation of
