densely so toward the sides, sparsely and unevenly, with large im- 

 piinctate patches toward the middle ; ajyex broadly and feebly emar- 

 ginate, more or less obsoletely and finely margined ; sides strongly 

 arcuate at apical third, thence strongly convergent and nearly straight 

 to the apex; distinctly sinuate before the base, finely and distinctly 

 beaded; hase transverse, generally very broadly, feebly sinuate 

 toward the middle, two-ninths to one-fourth wider than the apex, 

 rather coarsely margined laterally, more or less obsoletely so at 

 middle; apical angles obtuse, but not at all rounded; basal angles 

 slightly obtuse, not much rounded and rather prominent. 



Propleurm sparsely, irregularly punctate and more or less rugulose. 



Elytra two and one-half times longer than the prothorax, and, in 

 the middle, from one-fifth to nearly one-half wider than the latter, 

 widest at the middle; base truncate or feebly emarginate; humej'i 

 narrowh^ rounded, slightly prominent, and usually distinctly exposed; 

 sides evenly arcuate, apex narrowly rounded; disc moderately convex 

 on the dorsum, rather evenly rounded laterally, and arcuately decliv- 

 ous behind, rather coarsely, feebly and subasj)erately punctate, some- 

 times with very feebly impressed distant lines, the punctures rather 

 sparse, not much denser laterally, confusedly disposed, but often hav- 

 ing a feeble lineal arrangement. 



Eplpleurce moderate in width, gi'adually narrowing from base to 

 apex, superior margin feebly and broadly sinuate beneath the 

 humeri; surface finely, sparsely, and rather obsoletely punctate. 



Sterna densely punctate and rugulose. 



Parapleura densely punctate. 



Ahdomen more or less shining, sparsely punctate and rugulose; first 

 segment densely and strongly sculptured, and the fifth more coarsely

 joint feebly thickened at tip beneath, with tuft of ordinary spinules 

 more or less feebly developed.

 and somewhat obliquely declivous behind. Abdomen distinctly 

 oblique and moderately convex, more or less broadly impressed on 

 first two segments. Anterior spur of the anterior tibiae about one- 

 half as wide as that of the female, and somewhat gradually narrowed 

 in apical half, and acute.

 behind. Abdomen horizontal and rather strongly convex. Anterior
