of development in the oval, larval, or pupal stages may easily be 

 checked. Also the influence of the parental ( J ) facial detail, 

 becomes evident, and this influence presents itself only in those 

 specimens that were reared in approximately normal conditions of 

 temperature. 



Brood I.— The ova, bluish-green, 7-9 ribbed, were laid on the 20.5. by a V. io 

 ? , which was normal in facies, being in every way intermediate between ab. 

 mesoides and ab. teloides.

 belisaria, Obth., trans, one a cripple. All are dark in ground colour, 

 near brunnea: two specimens are ab. marginalis trans ( + ° pupae), one of 

 these is lighter in the ground colour. 28 specimens were set.
