Size moderate. Clypeus 9 wide, terminated by a little truncate 

 or bituberculate point ; cribrose with strong punctures. Head 

 and thorax rugosely punctured. Post-scutel very short, truncate, 

 crenulate. Metathorax very rugose above; the striae specially 

 distinct in the inferior moiety, the superior moiety being inure 

 smooth and punctured ; the inferior moiety forming a fossette, 

 separate and slightly margined superiorly. Lateral border of 

 the concavity rounded, not at all trenchant, the latero-superior 

 parts coarsely punctured, rugose; nevertheless one sees on each 

 side a little spiniform angle directed laterally and on the summit 

 a trace of an arcuate ridge, placed a little within, especially among 

 the males; superior angles % forming two salients, rugose and 

 blunted, separated from the post-scutel by a notch. Abdomen 

 conical, like satin, with golden reflections, having the border of 

 all the segments, save the first, quite strongly punctured ; but the 

 punctured band of the second quite wide and slightly impressed. 



Insect black, clothed with tawny hair. Two spots on the 

 summit of the clvpeus, another behind each eye, a dot on the 

 front, and a line under the scape of the antennas, tawny. The 

 summit of the clypeus is often entirely of this color, as well as 

 the inner border of the orbits. Posterior margin of the prothorax, 

 wing scales, a dot before the wing, post-scutel, and a dot on each 

 side, on the summit of the metathorax, ferruginous or tawny. 

 All the segments of the abdomen regularly bordered with yellow- 

 tawny ; the first more narrowly than the second. Legs black; 

 tibiae and tarsi ferruginous. Wings washed with ferruginous, a 

 little grayish at the end. 



%. Clypeus as long as wide; its inferior margin widely trun- 

 cate and armed with two little teeth separated by a wide straight 

 border, in the middle of which is often a third indistinct salient.
