new Genus of Blepharoce rid Flies. 



205 



of which is composed, in the fully-grown larva, of five fila- 

 ments, which arise practically co-basally. Two pairs of more 

 or less spherical anal papillae. Mouth-parts and suckers 

 rather closely resembling in structure those described by 

 F. Miiller. 



Type-species. Kellogg ina barnardi, Edw aids (1912). 



The genus differs trorn Paltostoma, to which in many 

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

 palpi, the absence of female mandibles and the shorter pro- 

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

 tarsal joint ; in the different arrangement of the spines of 

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

 and in the different anal papilla?. To Kdlvggina it is more 

 closely related, the 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 Kellogg ina. 



1. Elporia barnardi, Edw. 



As my original description of the head of A', barnardi was 

 incomplete and inaccurate in several respects, it is necessary 

 to give a redescription. In the first place, it must be stated 



Fis. 1. 



Fiar. 2. 



Elporia barnardi. 



Fig. 1. — Head of male ; diagram showing division of the eyes, 

 Fig, 2.— Head of female, to show the same, 



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 antennas.
