acute, and recurved; the surface is moderately strongly rugulose, with a longitu- 
dinal smooth ridge across the disc. The elytra rather broader than the thorax, 
14 times the length of their width at the shoulders, broadest about the middle, 
not mnch contracted towards the apex, the apex of each elytron broadly rounded ; 
the shoulders are rounded, recurved, furnished with a minute acute spine; at the 
base the elytra are strongly arched, deeply impressed on each side below the 
humeral angles, towards the apex flattened; the sarface is moderately strongly 
rugose at the base, finely granular towards the apex. The legs are uniformly red- 
brown, moderately thickly and strongly punctured. Abdomen shining, with its sides 
and the whole surface of its apical segments sparingly but distinctly punctured. 
Length, 22 lines.

var. VARUIPES. A typo differt tantum femorum dimidio basalt piceo- 
vel clare rufo. 
The 2 is remarkable for its broadened shape, with the elyt7 
abruptly and broadly rounded at the apex without trace of truncatuj 
The variety appears to offer no other difference from the type than tu: 
red base of the femora; the elytra in the @appear rather more sinuate 
truncate with the sutural angle produced, but obtuse; all gradation. 
however, are found between it and the type. 
Many examples, taken by Mr. Buckley in the Macas district, 
Equador, on rocks, in the middle of streams.
