The genus differs trom I'allostoma, to wliicli in many 

 respects it is obviously related, as follows: — the longer male 

 Iial])i, the absence of female mandibles and the shorter pro- 

 boscis, the divided eyes, and in the structure of the last 

 tarsal joint ; in tiie different arrangement of the spines of 

 the larva, the smaller number of gill-filaments in each tuft, 

 and in the different anal papilla?. 'Jo Kellofjgina it is more 

 closely related, tiie only important difference which can at 

 present be pointed out being in the divided eyes. Other 

 differences, however, will probably be found when more 

 information is available as to the structure and life-history 

 of KeUo(i<jina.

As my original description of the head of K. harnardi was 

 incomplete and inaccurate in several respects, it is necessary 

 to give a redescriptiuu. In the first {)lace, it must be stated

that in the figure of the female fly (Ann. & Mag. Nat. Hist, 

 ser. 8, vol. ix. pi. xx. fig. 1, 1912), the head depicted is really 

 that of the male and not the female, the latter sex having a 

 much broader front and larger terminal joint to the antennae.
