APPENDIX II. 331 



Dr. Scliiner's work, Reise, etc. der Novara, Dipiera, docs not 

 contain any further details, except the description of the species 

 P. nitens and a figure. Peripheroptera is evidently related to 

 Dicranomyia ; like some species of the latter genus, it has a very 

 short pra3furca, and the tip of the first longitudinal vein is in- 

 curved towards the second. 



GYSrOPLISTIA' Westw. 

 (Section LIMNOPHILINA ; compare p. 192.) 



Gynoplistia Westw., Lond. and Edinh. Phil. 3Iag. YI, p, 

 280 (syn. Anoplistes Westw., Zool. Journ. No. 20), is character- 

 ized thus : — 



" Related to Ctenophora. Antenna unipectinate in both, sexes, % 18-, 

 5 17-jointed; venation like that of Ctenoph. Jiaveolata." 



■Three species from New Holland and a fourth from North 

 America are described. The author divides the genus in two 

 sections : one, with the male antennae having the joints 8-1 T 

 unipectinate ; the other, the joints 3-17. 



Macquart {Dipt. Exot. I, 1, p. 43) adds some new characters 

 to the generic description, and in a subsequent volume (1. c. 

 Suppl. I, p. 10) observes that Gynoplistia belongs to the Tipu- 

 lidse with short palpi, and not to those with long palpi, as might 

 be inferred from Mr. Westwood's statement on its relationship 

 to Ctenophora. 



Those Gynoplistiae which I have seen in the European collec- 

 tions undoubtedly belong to the section Limnophilina ; their 

 venation is like that of a Limnophila with five posterior cells ; 

 the structure of the male genitals of an Aastralian species w^hich 

 I have seen shows the opercule mentioned by Macquart (I. c. p. 

 43). I had no opportunity for studying these species in detail ; 

 nor do I know whether a Gynoplistia, from South America, 

 which I have seen in the Berlin Museum, really belongs to the 

 same genus with the Australian species ; the degree of re- 

 lationship of Gynoplistia to Ctedonia Phil, is likewise unknown 

 to me.
