 fig. 156. 



Flavo brunneus vel rufescens, subtus pallidior, capile cum lamina prima 

 dorsali rubro-castaneo, antennis pedibusque flavis ; minus robustus, sub- 

 laevis ; capite manifesto marginato, suborbiculari. Antennae breviusculse, 

 breviter parcius hirsutae, 17 articulate, articulis ultimis longis vel per- 

 longis. 



Metameri quarti prosterni margo anterior medius manifesto callosus, 

 leviter productus, subrectus vel obscure sinuatus. 



Pedes anales glabri, longi, spina inferiore magna, interiore parva. 



Laminae dorsales praeter priores in lateribus manifesto marginatae.

 perforatae, in spinam robustiorem, breviorem productae. 



Lamina ultima ventralis latiuscula, valde angustata, post subrecta. 



Long. 65 mm. 



Having compared typical specimens, both of the Sc. sexspin- 

 osus and of the Sc. spinicauda Wood, I cannot perceive any 

 true or specific difference between them. 



This species is very common and spread over the greater part 

 of North America ; I have seen specimens, preserved in the 

 Museum of Comp. Zool., from Frederick county, Md., P. R. 

 Uhler ; Massachusetts, Miss A. M. Edmands, Cambridge, Mass.; 

 Berkshire, Tioga county, N. Y.; Centre county, Pa., Sualer ; 

 Virginia, Crandall ; Pennington's Gap, Lee county, Va.; Ross- 

 well, Ga., Mr. King; Yellow Springs, Ohio; Rocky creek, Gray- 

 son county, Ky., F. W. Putnam ; Macgregor, Iowa, Davis ; Rit- 

 chie county, W. Va., N. E. Ingersen ; San Mateo, Cal., A. 

 Agassiz (Sc. spinicauda, the type of Mr. Wood).
