$. Scape more than twice as long as broad; antennae longer than 

 the whole insect, measuring 9 mm. in length. Face shining, indis- 

 tinctly punctured, with a longitudinal sulcus on the upper half; 

 front and vertex smooth and shining; head not narrowed behind 

 the eyes. Thorax and median segment smooth and shining; 

 parapsidal furrows distinct, hut shallow. Raised area of the first 

 tergite broad, almost smooth, distinctly margined. Second tergito 

 with a lanceolate raised median area, which extends very narrowly 

 almost to the apex, a small elongate-ovate subconcave space on 

 each side of the area; the apical margin of the segment broadly 

 and shallowly emarginate, the second suture smooth. Anterior 

 angular areas of the third tergite small; the whole abdomen smooth 

 and shining. First abscissa of the cubitus bent near the base, 

 recurrent nervure received before the first transverse cubital 

 nervure; nervulus interstitial.

The second suture is interrupted in the middle by a 

 narrow ridge, but there is no raised area on the third 

 segment.

Long, (i mm. ; terebrae long. 4 mm. 



$. Antennae about equal in length to the whole insect. Very 

 similar in structure and sculpture to /. pallidicolor; but the raised 

 areaof the second tergite is broader, and bounded by deep smooth 

 grooves, not by a broader subconcave area, the raised spaces at the 

 basal angles are also much larger, almost extending to the basal 

 angles of the raised area ; the lateral grooves reach the apex, which 

 is not the case in pallidicolor; the third tergite has a small, raised, 

 triangular area at the base, and the areas at the anterior angles aro 

 arge.
