Georgia, where Say's types were from. If ray opinions in regard to 

 these two species are false, the name maryi-mitus must at all odds be 

 given up and J-uliiN americce-borealis* of Palis, de Beauvois be used in 

 stead. 



This species must now stand as Hpirobolus spiniyertix Wood.

As 2)u>iill'UN was preoccupied, Brandt, in 1841, proposed the name 



instead. But since this species belongs to the genus 

 of Koch it should now stand as Nemasoma intnulum.

This species on account of its rather imperfect description seems to 

 have caused considerable trouble in regard to its identification, Euro- 

 pean writers considering it the same as glauscescens Koch, and closely 

 allied to complanatus of Europe, in which they have been correct, while 

 American authors liave referred to it another species the moniliorix 

 of Koch. This latter species has the lateral cariiue finely denticulate 

 and the squamiform divisions much elevated, while in serratus, accord- 

 ing to Say's description, the lateral cariiue have only 3 or 4 denticula 

 tions and the squamiform divisions low.

This well-known species, which was afterwards described as new by 

 Koch and made the type of the genus Scytonotus, should now stand as 

 ScytoHotux yrunnlainx (Say). 



9. Polyeenus fasciculatus Say. Journ. Acad. Nat. Sci. Pliila.. 108, 1821. 



This rare species still retains the name given to it by Say. 

 Its liabitat is from Massachusetts to Indian Territory, and it docs 

 not seem to be found in the North Central States.
