basal joint expanded into a large eye-cap, which is thin and 

 cnp-like anteriorly. Labial palpi hidden on the under surface 

 of the head, short, drooping, with the terminal joint very 

 short. No maxillary palpi. No tongue.

 minute black dot at the extreme apex of the wing. Hind- 

 wings and cilia somewhat yellowish-white. 



This insect is very interesting, as it is the first extra-Euro- 

 pean member of the genus, as well as I can ascertain, that 

 has been described. The imago was found on the table under

 slightly injured, the stalks of the antennas having been burned 

 oft* and the cilia of one pair of wings a little burned. 



None of the larva? belonging to this genus have been dis- 

 covered.*

 which resembles it closely in many respects. These insects 

 must be handled very carefully when they are taken, as the 

 labial palpi are easily detached even whilst they are living.

 the costa, extending from the base to an orange-yellow costal 

 spot at the beginning of the apical cilia, and deeply excised 

 in the middle of the wing. Beneath the excised portion and 

 near the inner margin is a short, steel-blue streak, and the 

 costal streak emits a slender line to the inner margin, opposite
