ANNOTATED LIST OF BRITISH ANTH03IYIIDM. 



BT E. H. MEADE. 



{Co)itinued from p. 14.) 



All the remaining species in this Family have the eyes widely 

 separated in both sexes, and are thus related to the smaller acalypte- 

 rate Muscidce ; their calyptra or alulets are always, however, more or 

 less highly developed, so they must be retained among the AntJiomyiidce. 



With the exception of those in the peculiar genus Lispa, Meigen 

 included almost all the other species in the genus Gcenosia ; they 

 differ, however, so much from each other in the size of the alulets, in 

 the degree of pubescence of the arista, and in other characters, that 

 it is necessary to divide them into a number of groups or genera, 

 which I will briefly arrange or analyze in the following table : 



A. Alulets large, with unequal scales. 



B. Palpi with dilated extremities Lispa, Latr. 



BB. Palpi of the ordinary shape. 



C. Arista plumose Caeicea, Desv. 



CC. Arista pubescent or bare. 



D. Abdomen of $ narrow, cylindrical, and with projecting appen- 

 dages Machoechis, Rnd. 



DD. Abdomen of $ clubbed at the end, and without projecting ap- 

 pendages. 

 E. Internal transverse vein of wing opposite the end of the 

 axillary vein. 



F. Forehead and epistome prominent... 



Melanochelia, Rond. 



FF. Forehead and epistome unprojecting... 



C^nosia, Meig. 



EE. Internal transverse vein opposite the end of first longitudi- 

 nal vein Atheeigona, Rond. 



AA. Akdets small, with equal sized scales. 



Gr. Arista plumose, or sub-plumose. 



H. Anal vein prolonged to the margin of wing.., 

 Mtcophaga, Rond. 



HH. Anal vein shortened Chelisia, Rond. 



GG-. Arista pubescent or bare ScH.ffiNOMYZ A, Hal. 



23. LISPA, Latr. 

 Gen. cli. — Eyes bare, widely separated in both sexes ; arista plu- 

 mose ; palpi with dilated extremities ; alulets with the lower scale 

 much longer than the upper one ; anal vein elongated, but not reaching 

 the margin of the winjr.
