? . Clypeus opaque, the apical margin sliining and very 

 narrowly and shallowly excised in the middle ; eyes separated 

 on the vertex by a distance equal to about two-thirds of the 

 length of the second joint of the flagellum. Mesonotum 

 opaque, pruinose ; with a delicate impressed line from the 

 middle of the anterior margin, not reaching more than halfway 

 to the middle of the segment ; a similar short impressed line 

 on each side before the tegulse. Scutehum smooth and 

 slightly shining. Median segment longer than broad, mar- 

 gined at the apex ; transversely striated, the stria3 distinct at 

 the base, obsolete on the apical half; a very delicate longi- 

 tudinal carina from the base not reaching the apex ; the 

 surface of the posterior truncation with a deep median sulcus, 

 transversely striated at the sides, the strise obsolete in the 

 middle. Abdomen pruinose ; pygidial area rather broadly 

 truncate at the apex, finely rugose, sparsely clotlied with very 

 short pubescence which changes according to tiie light from 

 fuscous to pale golden, a few strong fuscous setae on the 

 apical margin. Basal sternites pruinose ; tlie second at the 

 base with the usual structure of the genus. Comb of the 

 anterior tarsus ratlier short, tlie basal joint with four spines ; 

 tarsal ungues long, with a small triangular tooth near the 

 middle. First abscissa of the radius as long as the second 

 and third combined, the fourth longer than the first ; radial 

 cell narrowly truncate at the apex ; recurrent nervures very 

 narrowly separated on the cubitus.

 a minute tubercle on each side at the apical angles. Eyes 

 separated on the vertex by a distance equal to tiie length of

 than the third. Thorax subopaque, coriaceous. Median
