 nearly linear frons, flush with eyes for a considerable distance. 

 Frons in both sexes after a certain distance projecting abruptly 

 forward into a strong prominence bearing the antennae at the tij). 

 Below the anteiuice, the face is slightly cut away. Lower part of 

 head extremely produced into a nearly i)orrectbare conical rostrum, 

 not produced below eyes at sides, much longer than in lihiw/ia, and 

 up to nearly three times as long as width of eye in profile. 

 Proboscis about twice as long as rostrum, very slender, cylindrical, 

 capable by means of its membranous basal part of being prolonged 

 to a greater length than that of the whole body. Antennae 

 normal, 3rd joint rounded or ovate. Thorax subquadrate ; 

 scutellum normal, semicircular; both densely pubescent. Abdomen 

 approximately ovate, arched, tip narrowed, pubescent. Genital 

 organs curved under tip of abdomen. Legs rather long and 

 strong, simple, moderately pubescent. Winr/s with a distinguishing 

 venation. Subcostal cell with a peculiar row of about seven or

 before its upward turn, apical section wavy, closing 1st posterior

 of angled as in most genera; anal vein continued forward for a

This genus is one of the most conspicuous in the family. Its 

 extremelv produced conical rostrum and still longer proboscis, its 

 abnormal venation (due to the numerous additional veinlets in 

 the subeostal cell), and the very distal position of the anterior 

 cross-vein, with the peculiarly curved 1th vein and jirolongation
