Family 29. nUSCID/C. Typical Flies. This family is very numerous, and embraces about two-thirds 



of the whole order. It needs, therefore, a separate key. 



KEY TO THE MUSCID^E. 



Srn-FAMiLY I. Upper cell of wing ending near point, closed or nearly so. 

 Bristle at end of feeler, smooth and bare 



one side bare, the other comb-like 

 feathery at foot, bare at point 

 featlier-like to the end body bristly 

 body bristly only at last rings 



Tachinidcs, 



(Stonii>\y>.) 



Sacrofkaga. 



Dexia. 



A/iisca. 



SOB-FAMILY II. Upper cell wide open. 



A scale covering the balancers in place of hind-wing and a seam across the breast-part Anthomyia am! Hylemia 

 The scale very small or entirely wanting; the seam across breast-part incomplete or wanting. 



Here belong many families of small flies. The veinings of their wings lie between Anthomyia and Pliora. The 

 scientific divisions are made on small characters, and are often very difficult to recognize in such delicate objects. 

 A is called the auxiliary vein; I is called the first length-vein from which the forked second length-vein branches. 

 Wing similar to Anthomyia. 

 Vein A and I separate 



Vein A and I, but separating near the front edge 

 Vein A close to I, cells large 

 cells small 



Wing less complete than Anthomyia. 

 Vein A close to i, only one cell 

 Vein A and i grown together 



separate near shoulder 

 Vein A only a slump 

 Vein A entirely wanting
