It may be cLddEci that Gasterophiliis has no incubating uterus, 

 but that the large ovaries are packed with eggs which come down 

 a few at a time for deposition. The eggs of the above nasalis 

 female show no incubation, and the chorion is transversely corru- 

 gated so that it holds on insertion in the skin. All the records of 

 lip and muzzle oviposition of this species that I have seen state 

 that the eggs are attached to the hairs. This might easily happen 

 when the fly misses its mark, and no doubt it misses frequently, 

 but the effort is evidently directed at the tender skin of the lips. 

 The eggs are sticky when freshly extruded, and the fly may even, 

 at times, inadvertently leave them on the hairs of the throat when 

 caught by the convulsive movements of the intended host. This 

 would explain throat oviposition records.
