ANNOTATED LIST OP BRITISH ANTHOMYilDJE. 



BY B. ir. MEADE. 



{Continued from p. 14.) 



All the I'cmainino; species in this Family have the eyes widely 

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

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

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



With the exception o£ those in the peculiar genus Lisjoa, Meigen 

 included almost all the other species in the genus Ccenosia ; 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 anal3^ze 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 Caricea, Desv. 



CO. Arista pubescent or bare. 



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

 dages MAcnoRCHis, End. 



DD. Abdomen of S 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 .. 



Melanochklia, Eond. 



FF. Forehead and epistome uuprojecting... 



C^NOSIA, Meig. 



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

 nal vein Atheeigona, Eond. 



AA. Alulets small, with equal sized scales. 



Gr. Arista plumose, or sub-plumose. 



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

 Mycophaga, Eond. 



HH. Anal vein shortened Chelisia, Eond. 



GG. Arista pubescent or bare Sch^enomyza, Hal. 



23. LISPA, Latr. 

 Oen. ch. — Eyes bare, w^idely 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 marsrin of the winir.
