?he tiny insect for which this genus is established is, as will be 
rom the characters given above, a most anomalous little crea- 
Its appearance and characters leave no doubt that it must be 
1 among the true Aleocharidce, though in the elongate lobes of the 
Ise it clearly approaches the Myllcence, and by the great size of the 
joint of the maxillary palpi, as well as by the two-jointed labial 
the Gyrophcence. On the whole I think it is best placed near 
5, which approaches ActocJiaris in more than one respect, as re- 
the structure of the trophi.
