Pezomachus ragans, Oliv.

 is undescribed, I here give a description. 



Niger, abdominis medio pedibusque runs, femoribus et 

 tibiis posticis piceis ; alis completis. 



Subopaque, finely and densely punctured ; head seen 

 above somewhat square, seen in front subrotund, rather 

 wider than long ; cheeks slightly rounded, not descend-

 from the face, rounded at the apex, a moderate pro-

 the space between the eyes wider below than above. 

 Antennae slender, slightly swollen from just before the

 joints of flagelluru of equal length, the 1st about four

 of the mesothorax; metathorax, seen from above the 

 upper part is not quite so long as the width between the 

 spiracles, without areae, posterior transverse line strongly 

 developed, the punctures or reticulations running trans- 

 versely backward from the centre, forming wavy delicate 

 rugosities ; back part slightly sloping, with no perpen- 

 dicular lines, but a distinct costa at the bottom ; 1st
