This striking species is one of the easiest forms of the genus 

 to recognize. The rounded yet clearly indicated lateral car- 

 inae of the pronotal disk in both sexes will serve to distinguish 

 this form, while the strongly arcuate character of the caudal 

 margin of the same disk and the great length of the lateral lobes 

 of the pronotum will also prove of service. The form of the male 

 cercus is uniciuc in the genus. 



Morphological Notes. — In this species the pronotal form ex- 

 hibits the same features of individual variation found in other 

 members of the genus, the greatest (caudal) width of the disk 



2' Previously recorded by the present authors as dorsalis (Proc. Acad. 

 Nat. Sci. Phila., 1910, p. 596, (1911)).
