In the number of joints in the maxillary and labial palpi, this genus agrees with 

 Monedula ; but it differs from it in the anterior ocellus being linear and transversely 

 curved, not roundish or reniform. The metathorax is compressed at the sides and 

 excavated behind ; the radial nervure forms with the third transverse cubital nervure 

 an acute angle; and the eighth ventral segment in the male has three spines. The 

 genus is only known from North, Central, and South America.

Antennae black, the scape yellow beneath ; the flagellura with a microscopic pile ; 

 the third joint twice the length of the fourth. Head closely punctured ; the front and 

 vertex covered with moderately thick and long cinereous or fuscous hair ; the face and 

 clypeus with a whitish pubescence ; the orbits broadly in front, narrowly behind, the 

 clypeus (except a large irregular transverse mark at the base and a small one in front 

 of this), the labrum, the mandibles (except the tips), and a short narrow line on the 

 vertex touching the orbits, yellow. Thorax shining, closely and rather strongly and 

 evenly punctured. Prothorax black, yellow at the top ; two oval spots in front on the 

 meson otum, a line before and one behind the tegulse, a small mark on either side of 

 the scutellum, the postscutellum, a curved line along the edge of the metanotum, the 

 projecting angles of the latter broadly, and a large mark on the mesopleurse, yellow. 

 There is an interrupted yellow line on the abdominal segments, the lines forming this 

 becoming shorter and more widely separated towards the apex, that on the penultimate 

 segment being twice as broad as long ; on the last segment are two small marks. Last 

 segment bearing large punctures, rugose at the base. The basal ventral segment is 

 almost entirely black ; the others bear black, transverse bands ; the last ventral segment 

 is entirely black. Legs yellow, the anterior coxae yellow beneath, the four hinder coxse 

 yellow at the apex ; the femora broadly lined above and beneath with black.
