(in extreme cases actually preventing the full unfolding and 

 flattening of the wings, see fig. 10 and p. 219) both wings are 

 affected in all but one instance. Can this be a mutilation or 

 deformation acquired by the pupal wing in the cell due to some 

 cramping condition, or perhaps to the manipulation of the still 

 damp unexpanded wings by the nurses in the few moments im- 

 mediately after the emergence of the bee from its cell? Of the 

 right fore wings 23 show " var. i complete " (entire absence of 

 a short cross vein) while 32 left fore wings show this condition. 

 Of the individuals showing this condition in either right or left 

 wing, sixteen show it also in the opposite wing, while one shows 

 "var. i complete" in one wing coincidently with "var. i in- 

 complete" in the other, or " var. i incomplete" in both. 



In the hind wings of this lot of drones from cells the follow- 

 ing conditions occur: Of the 12 cases in which a complete cell 

 is interpolated in one or the other wing the opposite wing has a 

 similar cell in 3 cases, shows no variation in one case, and some 

 variation in five cases. A deformation somewhat like that 

 referred to as occurring (in several cases) in the front wing 

 occurs in the right wing of one individual coupled with only 

 " slight " variation in the opposite wing. In 12 right wings 

 there is a spur at i " slight" to " marked," and such a condi- 

 tion occurs in 16 left wings. Of these cases the condition 

 occurs coincidently in both wings in 7 cases. 



Considering now the metameric conditions in the same lot we 

 note that in the two cases of interpolation of a new cell in the fore 

 wing, the same individual shows in neither case the similar in- 

 terpolation of a cell in the hind wing of the same (or other) side, 

 so that it is also the fact that in the 12 cases of such an interpo- 

 lation of a cell in the hind wing, no individual shows a similar 

 variation in the fore wing of the same (or other) side (one case 

 shows an incomplete cell in one fore wing). In one case of the 

 12 cases however both fore wings show the "deformation" 

 condition. Also in the two deformation cases in a hind wing 

 both individuals show " deformation " of both fore wings. 



Taking up the correlation conditions of the variation in num- 

 ber of costal hooks in the hind wings, we find in the lot of 300 

 drones from the laboratory hive, in which the modal numbers
