Of this Family of the Diptera eight species were obtained in the Seychelles by 

 Mr Hugh Scott, and a ninth on the distant island of Aldabra by Mr J. C. F. Fryer. Six 

 of the nine are new and admit of description ; two were published long ago ; and the one 

 remaining can only be placed in its genus at present. The nine species are : 



Brunettia indica, sp. nov. Philosepedon hutneralis, Hoffmann. 



Panimerus scolti, gen. et sp. nov. Philosepedon triungtdatus, sp. nov. 



Notiocharis insignis, gen. et sp. nov. Telmatoscopus fryeri, sp. nov. 



Psychoda altertiata, Say. Sycorax, sp. ^ 



Psychoda solitaria, sp. nov.? 



So far as they are now known, the genera of the whole Family can be assorted into 

 four principal Groups, by referring to the wings and antennae. These Groups, not 

 necessarily of the status of Sub-Families or Tribes, contain nearly related forms and 

 distant kindred, like a chart depicting archipelagoes with solitary outliers. In the 

 Seychelles two of these Groups only are represented. For reference a figure (PL 26, fig. I) 

 is given of a wing of a ? fly selected out of another Group, and lettered in accordance 

 with Comstock and Needham's terminology of nervures. 



This figure (PL 26, fig. 1) resembles the neuration of wings of all of the genera (except 

 Sycorax) in the collection in one particular : the anterior basal cell is bounded in front 

 by the main stem of the radial sectors, almost exclusively, so close to the wing-roots does 

 R* branch off innw R\ But the first six of the genera all (except Notiocharis) have 

 wings apically pointed at the end of R" ; and none of the eight (except Panimenis) has 

 the Sectorial Fork pedicellate to the anterior basal cell. 



Brunettia is an Indo-Malayan genus, nearly related to the European genus Pericoma 

 Halid., Walk., Ins. Brit. Dipt. vol. iii. p. 256 (1856); as restricted by Eaton, Ent. M. 

 Mag., ser. 2, vol. vii. p. 121 (June 1897). 



Panimerus, represented by several species in Europe and Nortli Africa, contains the 

 Baltic Amber insect named Pericoma forrnosa by Meiniier, Ann. Mus. Nat. Hungarici, 

 iii. p. 243, pi. 7, figs. 1 and 2, antennae $ and ? (1905). 



Notiocha7'is may be endemic to tlie Seychelles.
