Head wider than long, 1 mm. : 2 nmi. with the anterior margin 

 widely rounded. The eyes are small, round, composite, and situated 

 in the antero-lateral angles of the head. The first pair of antenna? 

 have the first two articles about equal in length; the third is twice as 

 long as the second. The flagellum is composed of ten articles. The 

 first antenna^ extend to the end of the peduncle of the second antenna?, 

 or to the antero-lateral angle of the first thoracic segment. The sec- 

 ond pair of antennge have the first two articles short, and subequal; 

 the third is a little longer than the second; the fourth is twice as long 

 as the third; the tifth is a little longer than the fourth. The fiagellum 

 is composed of thirty-three articles. The second antennae extend to the
