sharp, dorsum flatly convex. Mesonotum almost as long as broad,

broad, sides parallel, feebly convex, lateral margins sharp and raised, 
terminating on each side in a long slender spine, twice as long as broad at 
base; in profile pronotum and mesonotum, forming an evenly convex arch, 
suture sharply impressed, dorsum higher than lateral margins, anterior 
spine very slightly directed forward, anterior fourth of epinotum convex, 
straight behind, dorsum one-third longer than declivity, terminal spine long, 
slender and sharp, directed backward very slightly upward, declivity straight, 
at an obtuse angle. Node as long as broad, square, the four borders straight, 
posterior angles produced as long thin spines curved backward and slightly 
outward, fully three times as long as broad at base, between these long 
outer spines are two tubercles, on some examples these rudimentary spines 
are distinct, on others they are indistinct; in profile anterior and posterior 
faces vertical, posterior face twice as high as anterior face, dorsum straight,
