Dyar and Knab founded such new genera as Coelodiazeses and 
Mochlostyrax on purely larval characters ; the adults being unknown 
such names have not been adopted. The first named genus was, how¬ 
ever, applied to Anopheles harberi, Coquillett, and we see no reason for 
separating it. In any case, the larval characters given will not hold.
