distinct black spots. The hair and even the bristles on the hind 

 border of the last segment are white. The flat ovipositor is glossy- 

 black, as long as the two last segments of the abdomen and mode- 

 rately tapering towards the tip. The legs and anterior coxae are 

 dark yellow, with white hairs ; the thighs with a blackish stripe 

 somewhat covered with whitish dust. Wings not very narrow, hya- 

 line, with the base very slightly yellowish ; their black reticulation 

 is not very dense and not very delicate, extending towards the base 

 of the wing as far as the base of the discal cell, and dissolving 

 towards the axillary angle into some scattered spots ; stigma black, 

 with a whitish dot; the middle and posterior transverse veins rather 

 approximate.

Observation. — The proboscis of this species being short with the 

 suctorial flaps but moderately prolonged, attention is to be paid to 

 its true place, which is among the species with a geniculated pro- 

 boscis.

 Face excavated with the anterior border of the mouth much pro-
