stylis duabus rectis subulatis. 



Body long, cylindrical, nearly smooth, of moderate size. Head 

 nearly round, slightly attenuated hindward. Front prominent in front. 

 Proboscis cylindrical, rather short and thick, acute at the tip above. 

 Palp 1 ' four-jointed, decumbent, nearly cylindrical ; first, second, and 

 third joints of nearly equal length ; fourth longer, and a little more 

 slender. Antennas pilose ; second joint cyathiform. Prothorax dis- 

 tinct. Thorax elliptical. Scutellum small. Wings lanceolate, divari- 

 cated, rounded at the tips ; subcostal vein approaching the costa at the 

 stigma, then receding from it and joining it at four-fifths of the length, 

 connected with the radial by a short veinlet adjoining the stigma ; ra- 

 dial and cubital springing from a common petiole which is about one- 

 fourth of their length, and proceeds from the subcostal at two-thirds 

 of the length ; cubital forked very near its base, its hind fork forming 

 an angle near the base, and there connected by a transverse veinlet 

 with the third externo-medial ; the middle of this veinlet emits the 

 second externo-medial, and the latter is connected with the cubital by 

 another veinlet which forms an angle in front, and there emits the first 

 externo-medial ; third externo-medial angular at its junction with the 

 veinlet, which is continued across it to the subanal ; anal and axillary 

 complete ; discal areolet pentagonal. Abdomen long, cylindrical, with, 

 eight segments. Legs long, slender, nearly bare, unarmed ; tibire with 

 two very short apical spurs. Male. Antennae nineteen-jointed, a little 

 longer than the head and the thorax ; first joint moderately long, 

 slightly iucrassated at the tip ; second very short ; third elongated, 

 cylindrical ; fourth and following joints notched in the middle beneath ; 

 apical joints entire. Abdomen at the tip obtuse, subclavate, with 

 appendages. Fern. Antennae fifteen-jointed, at least twice the length 

 of the head ; first and third joints nearly cylindrical ; fourth and fol- 

 lowing joints also nearly cylindrical, a little thicker at the base. Ab- 

 domen with two straight subulate anal styles.
