Description. — Peach eye color is practically indistin- 

 guishable from orange eye color, although, as a rule, it 

 is a trifle darker than orange and does not have the range 

 of shades due to age which are observed in orange. In the 

 same culture, it is impossible to distinguish the two with 

 certainty. The double recessive of peach and orange is 

 probably indistinguishable from either eye color alone. 

 Homozygous peach rough flies have darker eye color than 

 orange rough flies, and are hard to separate from rough 

 alone. Peach eye color is similar to ruby and garnet of

Origin. — A single male with peach eye color was found 

 in a double recessive forked stump stock.

 wings, which have the marginal hairs clumped in irregu- 

 lar patches, especially on the posterior half of the outer 

 margin. The wings are pointed at the ends due to a long 

 notch, extending from the tip of the third vein to about
